Google treats good backlinks as votes of trust, so the number and quality of sites linking to you is one of the strongest ranking signals. Enter any domain — yours or a competitor's — and Nuqti counts its backlinks and referring domains, shows the strongest sites linking to it, the anchor texts they use and how many links pass authority (dofollow). Each number comes with what it means and what to do next. What it measures: - Backlinks: Total links pointing to the site - Referring domains: Unique websites linking — the number that matters most - Anchor texts: The words other sites use to link to you - Authority: How strong the site's link profile is, 0–100 FAQ: - Q: How do I check backlinks for free? A: Type the domain above and press Check backlinks. You get the total backlinks, referring domains, top linking sites and anchor texts. Signing in with Google is free and gives you every Nuqti tool on the free plan. - Q: What is the difference between backlinks and referring domains? A: Backlinks count every single link; referring domains count unique websites. 100 links from one site = 100 backlinks but 1 referring domain. Referring domains matter more for rankings. - Q: What is a good number of backlinks? A: There is no magic number — compare with the sites ranking for your keywords. Ten links from relevant, trusted sites beat a thousand from spammy directories. - Q: Are dofollow links better than nofollow? A: Dofollow links pass authority and help rankings directly. Nofollow links still send visitors and look natural, so a healthy profile has both. - Q: How often is the backlink data updated? A: Each check pulls fresh link data and keeps it for a few days so repeat checks are instant. ### Website Authority Checker URL: https://nuqti.com/seo-tools/website-authority-checker (Arabic: https://nuqti.com/ar/seo-tools/website-authority-checker) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/website-authority-checker?q=… Website authority (also called Domain Rating, DR, or domain authority, DA) estimates how much ranking power a site's backlinks give it. Sites with higher authority usually rank faster for competitive keywords. Nuqti ranks every domain against a link graph of over 130 million websites and turns its position into a 0–100 score, with the percentile and a plain-language verdict, so you know whether a site is new, growing, strong or very strong. What it measures: - Authority 0–100: Backlink strength on a logarithmic scale - Global rank: Position among 130M+ domains - Percentile: Stronger than X% of all sites - Next step: What to do to grow it FAQ: - Q: What is a good domain authority score? A: Under 15 = new or weak, 15–40 = growing, 40–70 = strong, 70+ = very strong. Compare with competitors in your niche rather than chasing a number. - Q: Is Domain Rating the same as Domain Authority? A: They are different brands of the same idea: a 0–100 score of backlink strength. Numbers differ between tools, but the ranking of sites is usually similar. - Q: How can I increase my website authority? A: Earn links from relevant, trusted sites: publish data and guides people cite, get listed where your customers look, and fix broken links pointing at you. - Q: Does authority directly affect Google rankings? A: Google doesn't use any third-party score, but the score summarises backlinks — and backlinks are a real ranking factor. ### Free Keyword Generator URL: https://nuqti.com/seo-tools/keyword-generator (Arabic: https://nuqti.com/ar/seo-tools/keyword-generator) Input: a keyword API: sign in (uses live data) Keyword research is finding the exact words people type into Google. The best opportunities are usually long-tail keywords: longer, specific phrases with less competition and clearer intent. Nuqti expands your seed into matching terms, questions and related topics from real searches, then adds monthly volume and a 0–100 difficulty to each one, so you can pick the ones you can actually win. What it measures: - Keyword ideas: Matching terms, questions and related topics - Search volume: Average monthly searches - Difficulty: How hard it is to reach page 1, 0–100 - Questions: What people ask — perfect for FAQs & blogs FAQ: - Q: How do I find long-tail keywords? A: Start with a short seed ("coffee"), then look at the questions and 3–5 word phrases the generator returns ("how to make cold brew coffee at home"). These have lower difficulty and convert better. - Q: Is this keyword generator really free? A: Yes. Run it, sign in with Google (free) and see the results. The free plan includes every Nuqti tool; Lifetime unlocks the full lists. - Q: Which keywords should I target first? A: Look for keywords with decent volume and low difficulty (under 30) that match what your page offers. - Q: Does it work in Arabic and other languages? A: Yes — type the seed in any language and choose the country, e.g. Arabic seeds for Egypt or Saudi Arabia. ### Keyword Difficulty Checker URL: https://nuqti.com/seo-tools/keyword-difficulty-checker (Arabic: https://nuqti.com/ar/seo-tools/keyword-difficulty-checker) Input: a keyword API: sign in (uses live data) Keyword difficulty (KD) estimates how hard it is to rank in Google's top 10 for a keyword. It mostly depends on how strong the pages already ranking are — especially how many quality sites link to them. Nuqti looks at the current top results, measures the authority and backlinks behind them and returns a 0–100 score with a plain-language reason and an estimate of how many referring domains you need. What it measures: - Difficulty 0–100: Easy → super hard, with the reason - Links needed: Referring domains to compete - Search volume: Monthly searches for the keyword - Who ranks: Authority of today's top results FAQ: - Q: What is a good keyword difficulty? A: 0–10 easy, 10–30 medium, 30–50 hard, 50–70 very hard, 70+ super hard. New sites should start under 20. - Q: How is keyword difficulty calculated? A: From the strength of the pages already in the top 10: their sites' authority and how many unique domains link to each ranking page. - Q: Can I rank for a high difficulty keyword? A: Yes, with a great page and enough quality backlinks — but it takes time. Target easier long-tail versions first to build authority. - Q: Why does difficulty differ between SEO tools? A: Each tool uses its own link data and formula. Treat KD as a relative guide, and look at the actual results too. ### Keyword Search Volume Checker URL: https://nuqti.com/seo-tools/search-volume-checker (Arabic: https://nuqti.com/ar/seo-tools/search-volume-checker) Input: a keyword API: sign in (uses live data) Search volume is the average number of times a keyword is searched on Google per month. It tells you the size of the demand before you invest in content or ads. Nuqti shows the monthly volume for your country, the 12-month trend (so you spot seasonality), what advertisers pay per click and how hard it is to rank — each with a short explanation. What it measures: - Monthly volume: Average searches per month - 12-month trend: Seasonality at a glance - Cost per click: Commercial value of the traffic - Difficulty: How hard it is to rank FAQ: - Q: How accurate is keyword search volume? A: Volumes are 12-month averages and rounded, so treat them as ranges. Trends and comparisons between keywords are very reliable. - Q: Why does the volume change by month? A: Many topics are seasonal — "air conditioner" peaks in summer. The trend chart shows that pattern. - Q: What is CPC? A: Cost per click — what advertisers pay on average for one click on this keyword. A high CPC means the traffic is commercially valuable. - Q: Can I check Arabic keywords? A: Yes, choose Egypt, Saudi Arabia, UAE or any other country and type the keyword in Arabic. ### Free SERP Checker URL: https://nuqti.com/seo-tools/serp-checker (Arabic: https://nuqti.com/ar/seo-tools/serp-checker) Input: a keyword API: sign in (uses live data) A SERP (search engine results page) is what Google shows for a query. Studying it tells you what kind of page Google wants — guides, product pages, videos — and how strong the competition is. Nuqti fetches the live results for your country and adds the authority, referring domains and estimated traffic of every page, plus features like AI Overviews, People Also Ask, videos and local packs. What it measures: - Top 10 results: Pages ranking right now - Authority: Strength of each ranking site - Est. traffic: Visits each page gets from this keyword - SERP features: AI Overview, People Also Ask, videos… FAQ: - Q: What does a SERP checker do? A: It shows the pages ranking for a keyword with SEO metrics, so you can judge competition and the type of content that ranks. - Q: Are the results personalised? A: No — they are a clean, non-logged-in view for the country you choose, close to what a new visitor sees. - Q: What are SERP features? A: Extra blocks like AI Overviews, featured snippets, People Also Ask, videos, images and maps. They take clicks away from normal results. - Q: How do I beat the top results? A: Match the intent, cover the topic better, and earn links — use the authority and links column to see the gap. ### Website Traffic Checker URL: https://nuqti.com/seo-tools/website-traffic-checker (Arabic: https://nuqti.com/ar/seo-tools/website-traffic-checker) Input: a domain, e.g. example.com API: sign in (uses live data) Organic traffic is the visitors a site gets from unpaid Google results. Checking a competitor's organic traffic shows how big they are in search and which topics work for them. Nuqti looks at the keywords a site ranks for in the US, Egypt and Saudi Arabia, multiplies each keyword's search volume by the click-through rate of its position and adds it up — so you see monthly visits, ranking keywords, position spread and the value of that traffic. What it measures: - Monthly visits: Estimated organic visits from Google - Ranking keywords: Keywords in the top 100 - Positions: How many in top 3, top 10… - Traffic value: What these visits would cost as ads FAQ: - Q: How accurate are website traffic estimates? A: They are modelled from rankings × search volume × click-through rate. Exact numbers vary, but they reliably show size and trends — great for comparing competitors. - Q: Does it include direct and social traffic? A: No — this tool estimates organic search traffic from Google. For your own site, connect Google Search Console in Nuqti for exact clicks. - Q: What is traffic value? A: What the same visits would cost if you bought them as ads. It shows how commercially valuable a site's rankings are. - Q: Can I see which keywords bring the traffic? A: Yes, after signing in you get the ranking keywords and positions; the full list is in Nuqti's Site Explorer. ### Keyword Rank Checker URL: https://nuqti.com/seo-tools/keyword-rank-checker (Arabic: https://nuqti.com/ar/seo-tools/keyword-rank-checker) Input: a domain (q) and a keyword (q2) API: sign in (uses live data) Your Google position for a keyword decides how many clicks you get: position 1 gets around 28% of clicks, position 10 about 2%. Checking your rank tells you how close you are to real traffic. Nuqti searches Google for your keyword in the country you choose, finds your domain in the top 100 and shows the exact position, the URL that ranks and the sites ranking above you. What it measures: - Your position: Where you rank in the top 100 - Ranking page: The URL Google shows - Who's ahead: The sites above you - Expected CTR: Share of clicks at your position FAQ: - Q: Why is my rank different when I search myself? A: Your own searches are personalised by history and location. Nuqti checks a clean, non-personalised result for the country. - Q: How often should I check rankings? A: Weekly is enough for most sites. Nuqti's Rank Tracker checks automatically and alerts you to changes. - Q: My site isn't found — what now? A: It means you're not in the top 100 for that keyword yet. Try a longer, more specific keyword or improve the page and its links. - Q: Can I check rankings in Arabic? A: Yes — type the Arabic keyword and pick the country. ### Website Speed Test URL: https://nuqti.com/seo-tools/website-speed-test (Arabic: https://nuqti.com/ar/seo-tools/website-speed-test) Input: a public URL, e.g. https://example.com/page API: sign in (uses live data) Page speed affects rankings, bounce rate and sales. Google measures it with Core Web Vitals: how fast the main content appears (LCP), how quickly the page reacts (INP) and how stable the layout is (CLS). Nuqti runs a full lab test on mobile and desktop and, when available, adds real-user data from Chrome visitors — then explains each metric and whether it passes Google's thresholds. What it measures: - Performance score: 0–100 for mobile and desktop - LCP: Time until the main content shows - CLS: How much the layout jumps - Total blocking time: How long the page is frozen FAQ: - Q: What is a good page speed score? A: 90–100 is good, 50–89 needs improvement, under 50 is poor. Mobile scores are usually lower than desktop. - Q: What are Core Web Vitals? A: LCP (main content load, good ≤ 2.5 s), INP (responsiveness, good ≤ 200 ms) and CLS (layout stability, good ≤ 0.1). - Q: Does page speed affect SEO? A: Yes — Core Web Vitals are part of Google's page experience signals, and slow pages lose visitors before they convert. - Q: How do I make my website faster? A: Compress and resize images, use modern formats (WebP/AVIF), remove unused JavaScript, use a CDN and cache, and lazy-load below-the-fold content. ### Free SEO Checker URL: https://nuqti.com/seo-tools/seo-checker (Arabic: https://nuqti.com/ar/seo-tools/seo-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/seo-checker?q=… On-page SEO is everything on the page itself that helps Google understand and rank it: the title, meta description, headings, content depth, images, internal links, structured data and indexability. Nuqti loads the page like Google does and runs over 20 checks. You get an overall score, what passed, what needs attention and the exact fix for each issue — written for humans, not just developers. What it measures: - SEO score: 0–100 from 20+ checks - Title & meta: Length and keyword placement - Content: Headings, word count, images - Links & schema: Internal links, canonical, structured data FAQ: - Q: What does an SEO checker check?

A: Yes — any public URL. ### Meta Tag Checker URL: https://nuqti.com/seo-tools/meta-tag-checker (Arabic: https://nuqti.com/ar/seo-tools/meta-tag-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/meta-tag-checker?q=… Meta tags tell search engines and social networks what a page is about. The title and description become your Google snippet; Open Graph tags control how your link looks when shared. Nuqti reads every meta tag on the page, measures title and description against what Google displays, previews the search snippet and social card, and flags missing canonical, robots or hreflang tags. What it measures: - Title tag: Length + Google preview - Meta description: Length + snippet preview - Open Graph: How your link looks when shared - Canonical & hreflang: Duplicate and language signals FAQ: - Q: How long should a title tag be?

A: og:title, og:description and og:image control the preview card on Facebook, LinkedIn, WhatsApp and X. - Q: Do meta keywords matter? A: No — Google ignores the meta keywords tag. ### Broken Link Checker URL: https://nuqti.com/seo-tools/broken-link-checker (Arabic: https://nuqti.com/ar/seo-tools/broken-link-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/broken-link-checker?q=… Broken links (dead links) point to pages that no longer exist. They frustrate visitors, waste Google's crawl budget and leak the authority your page could pass on. Nuqti opens the page, collects every link and tests each one — live. You see which links are broken (404/410), failing (5xx), slow or redirected, their anchor text and whether they are internal or external. What it measures: - Broken links: 404 / 410 / server errors - Redirects: Links that bounce to another URL - Links tested: Internal and external - Response time: Slow links that may time out FAQ: - Q: Why do broken links matter for SEO? A: They waste crawl budget, stop authority flowing through your site and create a bad experience — all signals Google cares about. - Q: How do I fix a broken link? A: Update it to the correct URL, link to a relevant alternative, or remove it. For your own deleted pages, add a 301 redirect. - Q: Does it check the whole site? A: This free tool checks the links on one page. Nuqti's Site Audit crawls your entire site. - Q: What is a redirect chain? A: A link that redirects more than once before reaching the final page. It slows users and crawlers — link straight to the final URL. ### AI Visibility Checker URL: https://nuqti.com/seo-tools/ai-visibility-checker (Arabic: https://nuqti.com/ar/seo-tools/ai-visibility-checker) Input: a domain (q) and a keyword (q2) API: sign in (uses live data) More and more people ask AI assistants instead of searching. If ChatGPT, Gemini or AI search answers never mention you, you're invisible to that traffic — even if you rank on Google. Nuqti asks leading AI answer engines your question, then checks whether your domain or brand is mentioned or cited as a source, which competitors appear instead, and how prominently. What it measures: - Mentioned?: Does the answer name your brand - Cited?: Is your site linked as a source - Who's recommended: Brands that appear instead - Prominence: How early you're mentioned FAQ: - Q: What is AI visibility? A: How often AI assistants and AI search features mention or cite your brand when users ask about your topic. - Q: How do I get recommended by ChatGPT? A: Be cited by the sources AI trusts: strong reviews and comparisons, clear product pages, mentions on authoritative sites and communities, and structured data. - Q: Which AI engines are checked? A: Leading AI chat assistants and AI search answers. Nuqti's Brand Radar tracks more engines and many prompts over time. - Q: Why do answers change? A: AI answers vary between runs. Tracking many prompts over time gives a reliable share of voice. ### DNS Propagation Checker URL: https://nuqti.com/seo-tools/dns-checker (Arabic: https://nuqti.com/ar/seo-tools/dns-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/dns-checker?q=… When you change a DNS record — move hosting, point a domain, add email — the change doesn't reach everyone at once. Each DNS server keeps a cached copy until its time-to-live (TTL) runs out, so for a while some countries see the new value and others still see the old one. That is DNS propagation. Nuqti asks 36 public DNS servers across 30 countries for your record at the same moment, groups the answers, and shows on a world map which locations already see the new value. The headline number is the share of servers that agree with the majority answer. What it measures: - Propagation %: Share of servers worldwide that agree with the main answer - Answer per server: The exact value each city/country gets - Response time: How fast each server answered, in milliseconds - Mismatches: Locations still showing an old or different value FAQ: - Q: How long does DNS propagation take? A: Usually minutes to a few hours; up to 48 hours in the worst case. It depends on the old record's TTL — a TTL of 3600 means servers may keep the old answer for up to one hour. - Q: Why do some locations show a different IP? A: They still have the old record cached, or your domain uses geo-routing/CDN that gives each region its nearest server (that's normal for big sites). - Q: Can I speed up propagation? A: Lower the TTL (e.g. to 300 seconds) a day before a planned change. After the change, you can't force other servers to refresh — you can only wait for their cache to expire. - Q: Which record types can I check? A: A, AAAA, CNAME, MX, NS, TXT, SOA and CAA — pick the type next to the domain box. ### DNS Records Lookup URL: https://nuqti.com/seo-tools/dns-lookup (Arabic: https://nuqti.com/ar/seo-tools/dns-lookup) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/dns-lookup?q=… DNS records are the domain's address book: A and AAAA say which server hosts the website, MX says where email goes, NS says who manages the zone, TXT holds verifications and email-security rules, and CAA says which certificate authorities may issue SSL for the domain. Nuqti queries all eight record types at once and explains each value in plain words — so you can confirm a hosting move, debug email or see how a competitor is set up, without typing nslookup or dig commands. What it measures: - A / AAAA: The server IPs that host the website - MX: The mail servers that receive email - TXT: Verifications, SPF and other rules — each labelled - CAA & SOA: Who may issue SSL, and the zone's master data FAQ: - Q: What is a DNS lookup? A: Asking the Domain Name System for the records stored for a name — for example the IP address (A record) of example.com. It's what your browser does before opening any site. - Q: Is this the same as nslookup or dig? A: Yes — it returns the same answers as nslookup/dig, for all common record types at once, and explains them. - Q: Why is a record missing? A: Either it doesn't exist (many domains have no AAAA or CAA), or it was just added and hasn't propagated yet — check it worldwide with the DNS checker. - Q: What does TTL mean? A: Time to live: how many seconds DNS servers may cache the answer before asking again. Lower TTL = faster changes, slightly more DNS traffic. ### TXT Record Lookup URL: https://nuqti.com/seo-tools/txt-record-lookup (Arabic: https://nuqti.com/ar/seo-tools/txt-record-lookup) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/txt-record-lookup?q=… TXT records hold text that other services read: Google Search Console and Microsoft 365 use them to verify you own the domain, SPF and DMARC use them to fight email spoofing, and many tools add their own verification strings. Nuqti reads all TXT records for the exact name you type (sub-domains like _dmarc.example.com or selector._domainkey.example.com work too) and labels each one: SPF, DMARC, DKIM, verification or other. What it measures: - All TXT values: Every text record published for the name - SPF / DMARC / DKIM: Email-security records spotted and labelled - Verifications: Site-ownership tokens (search consoles, office suites…) - TTL: How long the answer is cached FAQ: - Q: How do I check a TXT record? A: Type the domain (or full sub-domain) above and press Look up TXT. You'll see every TXT value published for that name. - Q: My new TXT record isn't showing A: DNS changes take time. Check the TTL of the old record and try the DNS checker to see which locations already have it. - Q: Can a domain have many TXT records? A: Yes — but only ONE SPF record (v=spf1). Two SPF records break email authentication. - Q: Are TXT records case-sensitive? A: The value is stored exactly as you typed it; most services compare verification tokens exactly, so copy-paste them. ### CNAME Record Lookup URL: https://nuqti.com/seo-tools/cname-lookup (Arabic: https://nuqti.com/ar/seo-tools/cname-lookup) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/cname-lookup?q=… A CNAME record makes one name an alias of another — for example www.example.com → example.netlify.app. It's how you connect sub-domains to hosting platforms, stores, CDNs and email tools. Nuqti reads the CNAME for the exact host you type, follows it to the final IP address, and names the platform behind it when it's recognisable — handy when you're connecting a domain or checking a competitor's setup. What it measures: - Alias chain: Every hop from your name to the final target - Final IP: The server address it lands on - Platform: The service or CDN behind the target - TTL: How long the alias is cached FAQ: - Q: What is a CNAME record? A: An alias: it tells DNS 'this name is the same as that name'. The browser then looks up the target's IP. - Q: Can the root domain have a CNAME? A: Not by the DNS standard — the apex (example.com) can't have a CNAME next to its other records. Many DNS hosts offer 'CNAME flattening' or ALIAS records instead. - Q: Why does my sub-domain show no CNAME? A: It may use an A record directly, or the CNAME hasn't propagated yet. Check worldwide with the DNS checker. - Q: CNAME vs A record? A: An A record points to an IP; a CNAME points to another name. Use CNAME when the platform may change its IPs. ### Nameserver Checker URL: https://nuqti.com/seo-tools/nameserver-checker (Arabic: https://nuqti.com/ar/seo-tools/nameserver-checker) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/nameserver-checker?q=… Nameservers (NS records) are the servers that hold your domain's DNS zone. If one of them is down, out of date or misconfigured, parts of the internet can't find your website or email. Nuqti finds the domain's nameservers, then queries every one of them directly: does it answer, does it serve the same zone version (SOA serial), how fast is it, which network is it on, and does it support IPv6. Six best-practice checks give a simple score. What it measures: - Nameservers: Every NS with its IP, network and country - Health score: Six best-practice checks out of 100 - SOA serial sync: Do all servers serve the same version - Speed: Response time of each nameserver FAQ: - Q: How do I find a domain's nameservers? A: Enter the domain above. Nuqti lists every NS record, the DNS provider behind them and the IP address of each server. - Q: How many nameservers should a domain have? A: At least two, ideally on different networks, so your domain keeps working if one goes down. - Q: I changed nameservers at my registrar — when will it work? A: The registry updates in minutes, but resolvers may cache the old NS for up to 48 hours. The DNS checker (NS type) shows progress worldwide. - Q: What is the SOA serial? A: The zone's version number. All nameservers should show the same serial; different serials mean one server hasn't received your latest changes. ### MX Record Lookup URL: https://nuqti.com/seo-tools/mx-lookup (Arabic: https://nuqti.com/ar/seo-tools/mx-lookup) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/mx-lookup?q=… MX (mail exchanger) records tell the world which servers accept email for a domain, and in what order. A wrong or missing MX record means lost email — usually without anyone noticing. Nuqti lists every MX record by priority, resolves each mail server's IP, network and reverse DNS, recognises the email provider (Google Workspace, Microsoft 365, Zoho…) and shows whether SPF and DMARC are published. What it measures: - Mail servers: Every MX in priority order - Provider & network: Who runs your email, and where - Reverse DNS: The name each mail IP reports — needed for good delivery - SPF & DMARC: Are the anti-spoofing records published FAQ: - Q: What does MX priority mean? A: Lower numbers are tried first. Servers with the same number share the load; higher numbers are backups. - Q: Why does my domain have no MX record? A: Then senders fall back to the A record, which rarely runs a mail server — so email bounces. Add the MX records your email provider gives you. - Q: What is a null MX ('0 .')? A: A domain that publishes '0 .' declares it never receives email. That's correct for domains used only for websites. - Q: MX changes aren't working yet A: Wait for the old TTL to expire and check worldwide with the DNS checker (MX type). ### DNSSEC Checker URL: https://nuqti.com/seo-tools/dnssec-checker (Arabic: https://nuqti.com/ar/seo-tools/dnssec-checker) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/dnssec-checker?q=… DNSSEC adds digital signatures to DNS answers so attackers can't send visitors to a fake server by poisoning DNS caches. It works through a chain of trust: the registry publishes a DS record that matches your zone's signing key (DNSKEY). Nuqti checks the DS record, reads the DNSKEY keys and their algorithm, and asks a validating resolver whether the answers verify. A broken chain is worse than no DNSSEC — validating resolvers will refuse to answer. What it measures: - Status: Secure, off, partial or broken - DS record: The fingerprint published at the registry - Signing keys: DNSKEY keys and their algorithm - Validation: Does a validating resolver trust the answers FAQ: - Q: Do I need DNSSEC? A: It's recommended for banks, governments and any domain where DNS spoofing is a risk. Most registrars and DNS hosts enable it with one click. - Q: What does 'broken' mean? A: A DS record exists at the registry but the zone isn't signed with a matching key — usually after changing DNS host without removing the old DS. Validating resolvers then fail to resolve your domain. - Q: What is 'partial'? A: The zone is signed (DNSKEY exists) but no DS at the registry, so nobody validates it yet. Add the DS record at your registrar. - Q: Which algorithm is best? A: ECDSA P-256 (13) or Ed25519 (15) are modern and compact. RSA/SHA-1 algorithms (5, 7) are outdated. ### WHOIS Domain Lookup URL: https://nuqti.com/seo-tools/whois-lookup (Arabic: https://nuqti.com/ar/seo-tools/whois-lookup) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/whois-lookup?q=… Every registered domain has a public registration record: the registrar it was bought through, when it was created and last updated, when it expires, its status locks and its nameservers. Owner contact details are usually hidden by privacy protection today. Nuqti finds the official registry for the domain's extension and reads the record directly (modern RDAP first, classic WHOIS as fallback), then turns the dates into a clear age and an expiry countdown. What it measures: - Registrar: The company the domain is registered with - Created & expires: Key dates with an expiry countdown - Domain age: Years since first registration - Status & locks: Transfer locks, holds and DNSSEC FAQ: - Q: Can I see who owns a domain? A: Only if the owner chose to publish it. Most registrars hide personal data (GDPR privacy). You'll still see the registrar, which you can contact about the domain. - Q: How do I know when a domain expires? A: The expiry date and a days-left countdown are at the top of the report. Expired domains usually enter a grace period of 30–45 days before they can be bought by others. - Q: What do the status codes mean? A: clientTransferProhibited = transfer lock (good). serverHold or redemptionPeriod = the domain is suspended or expiring. pendingDelete = it will be released soon. - Q: Is the domain available? A: If no registration record exists, Nuqti tells you the domain looks available to register. ### Domain Age Checker URL: https://nuqti.com/seo-tools/domain-age-checker (Arabic: https://nuqti.com/ar/seo-tools/domain-age-checker) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/domain-age-checker?q=… Domain age is the time since a domain was first registered. Older domains often have more history, links and trust — though Google says age alone isn't a ranking factor, it usually goes hand in hand with authority. Nuqti reads the creation date from the official registry, shows the age in years and days, and adds the expiry date and registrar so you can judge a domain before buying it or linking to it. What it measures: - Age: Years and days since registration - Registered on: The exact creation date - Expires in: Days until the registration ends - Registrar: Where the domain is registered FAQ: - Q: Does domain age affect SEO? A: Not directly. But older domains tend to have earned more backlinks and trust over time — that's what helps rankings. - Q: Is the age the same as the website's age? A: Not always. A domain may have been registered years before a site launched, or re-registered after expiring (the age then restarts). - Q: Why is the date missing? A: A few country extensions don't publish creation dates. Nuqti then shows what the registry does publish. - Q: How can I check a domain before buying it? A: Look at its age, its authority and backlinks (Nuqti website authority checker) and whether it's on spam blacklists. ### Website IP Lookup URL: https://nuqti.com/seo-tools/domain-ip-lookup (Arabic: https://nuqti.com/ar/seo-tools/domain-ip-lookup) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/domain-ip-lookup?q=… Every website lives on one or more servers with an IP address. Knowing the IP tells you who hosts the site, which country it's served from and whether it sits behind a CDN that shares IPs with many other sites. Nuqti resolves all IPv4 and IPv6 addresses for the host, then looks up each IP's network (ASN), organisation, country and reverse DNS name. What it measures: - IPv4 & IPv6: Every address the site resolves to - Network & owner: ASN and the organisation that owns the IP - Country: Where the network is registered - Reverse DNS: The name each IP reports FAQ: - Q: How do I find the IP address of a website? A: Type the domain above. You'll get every IPv4 (A) and IPv6 (AAAA) address it currently resolves to. - Q: Why are there several IPs? A: Big sites use load balancing or CDNs, giving several IPs (sometimes different ones per region). - Q: Is the country the server's real location? A: It's the country the network is registered in. With a CDN, visitors connect to the nearest edge server, not the origin. - Q: What is reverse DNS? A: The name an IP address reports about itself (PTR record) — often reveals the hosting company or server name. ### SPF Record Checker URL: https://nuqti.com/seo-tools/spf-checker (Arabic: https://nuqti.com/ar/seo-tools/spf-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/spf-checker?q=… SPF (Sender Policy Framework) is a TXT record listing the servers allowed to send email for your domain. Inbox providers like Gmail and Outlook check it; a missing or broken SPF sends your mail to spam — or lets scammers send as you. Nuqti reads your SPF record, follows every include: into a tree, counts the DNS lookups against the hard limit of 10, checks the final all policy, and names the email services you've authorised. What it measures: - SPF record: The exact record, parsed term by term - DNS lookups: How many of the 10 allowed you use - Include tree: Every service you authorised, expanded - Policy: What happens to mail from other servers FAQ: - Q: What is the SPF 10-lookup limit? A: Receivers stop after 10 DNS lookups (include, a, mx, ptr, exists, redirect). Above 10, SPF returns 'permerror' and your mail may fail authentication. Remove unused includes or flatten them. - Q: Should I use -all or ~all? A: ~all (soft fail) is the safe default while you set up DMARC. -all (hard fail) is stricter. Never use +all — it allows anyone. - Q: Can I have two SPF records? A: No. Two v=spf1 records = permerror. Merge them into one record. - Q: Is SPF enough to stop spoofing? A: No — combine SPF with DKIM and a DMARC policy. Check them with Nuqti's DKIM and DMARC checkers. ### DMARC Record Checker URL: https://nuqti.com/seo-tools/dmarc-checker (Arabic: https://nuqti.com/ar/seo-tools/dmarc-checker) Input: a domain, e.g. example.com API: GET https://nuqti.com/api/public/v1/tools/dmarc-checker?q=… DMARC tells inbox providers what to do with email that claims to be from your domain but fails SPF and DKIM: deliver it (p=none), send it to spam (quarantine) or reject it. Since 2024 Gmail and Yahoo require DMARC for bulk senders. Nuqti reads the _dmarc record, explains every tag (p, sp, pct, rua, ruf, adkim, aspf), shows your protection level on a 3-step scale and tells you exactly what to change next. What it measures: - Protection level: None, monitor, quarantine or reject - Reports: Where aggregate & failure reports go - Coverage: Share of mail the policy applies to - Score: How complete your setup is FAQ: - Q: What DMARC policy should I use? A: Start with p=none and a rua address to collect reports, fix your senders, then move to quarantine and finally reject. - Q: What is rua? A: The address that receives daily aggregate reports from inbox providers — showing every server sending as your domain. - Q: Does DMARC need SPF and DKIM? A: Yes. DMARC passes only when SPF or DKIM passes AND matches (aligns with) your From domain. - Q: Do I need DMARC if I don't send email? A: Yes — publish p=reject so nobody can spoof your domain. ### DKIM Record Checker URL: https://nuqti.com/seo-tools/dkim-checker (Arabic: https://nuqti.com/ar/seo-tools/dkim-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/dkim-checker?q=… DKIM signs every email you send with a private key; receivers check the signature against a public key published in DNS at selector._domainkey.yourdomain. A valid DKIM signature proves the message wasn't changed and really came from you. Enter your domain and, if you know it, the selector (found in an email's DKIM-Signature header as s=). Without a selector, Nuqti tries 50 selectors used by popular email services. For each key found you see its type, length and status. What it measures: - Keys found: Every selector with a published key - Key strength: 1024 / 2048-bit RSA or Ed25519 - Service: The email platform behind each selector - Record: The raw DKIM record, parsed FAQ: - Q: What is a DKIM selector? A: A name that lets one domain have several DKIM keys (one per service). Find it in a sent email's headers: DKIM-Signature: … s=selector. - Q: Is 1024-bit DKIM enough? A: 2048-bit is recommended today. 1024-bit still works but is weaker; below 1024 is unsafe. - Q: Why wasn't my DKIM found? A: Your selector may be custom. Open a sent email, view the original headers, copy the s= value and enter it in the selector box. - Q: What does 'revoked' mean? A: The record exists but its key (p=) is empty — the key was deliberately disabled. ### IP & Domain Blacklist Checker URL: https://nuqti.com/seo-tools/blacklist-checker (Arabic: https://nuqti.com/ar/seo-tools/blacklist-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/blacklist-checker?q=… Spam blacklists (DNSBLs) are databases of IPs and domains that sent spam or hosted malware. Inbox providers consult them: one listing on a major list can send all your email to spam or get it rejected outright. Enter a domain and Nuqti finds its website IP and mail server IPs, then checks them on 20 IP blacklists — plus the domain itself on 5 domain blacklists — showing a clear listed/clean grid. What it measures: - Listings: How many lists flag you right now - IPs checked: Website & mail server IPs found - Domain lists: Spam-link databases for your domain - Clean: Lists where you're clear FAQ: - Q: Why is my IP blacklisted? A: Usually a hacked account or form sending spam, a shared server where another customer spammed, or a 'dynamic' home IP that lists block by default. - Q: How do I get delisted? A: Fix the cause first (change passwords, secure forms), then use the list's removal page. Many lists remove you automatically after a quiet period. - Q: Is every blacklist important? A: No. Spamhaus, SpamCop and Barracuda matter most for email delivery. Small lists have limited impact. - Q: Can I check a shared hosting IP? A: Yes — enter the IP directly. If you're listed because of a neighbour, ask your host for a clean IP. ### SSL Certificate Checker URL: https://nuqti.com/seo-tools/ssl-checker (Arabic: https://nuqti.com/ar/seo-tools/ssl-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/ssl-checker?q=… An SSL/TLS certificate encrypts traffic between visitors and your site and proves the site is really yours. If it expires, doesn't cover the exact host name, or is missing an intermediate certificate, browsers show a full-page 'Not secure' warning and visitors leave. Nuqti opens a real TLS connection, reads the certificate and its chain, checks trust, host name coverage, days left, protocol version, whether old TLS 1.0/1.1 is still accepted, the HTTP→HTTPS redirect and HSTS — then scores the setup. What it measures: - Days left: Time until the certificate expires - Issuer & coverage: Who issued it and which names it covers - Chain: Every certificate up to the trusted root - Health score: Trust, protocol, redirect and HSTS checks FAQ: - Q: How do I check when my SSL certificate expires? A: Enter your domain — the days left and expiry date are the first numbers in the report. Free certificates last 90 days and should auto-renew. - Q: Why does my site say 'Not secure' with a valid certificate? A: Often the certificate doesn't cover that host (e.g. www vs bare domain), the chain is incomplete, or the page loads mixed http:// content. - Q: What is a certificate chain? A: Your certificate is signed by an intermediate, signed by a trusted root. Servers must send the intermediate; if not, some devices can't verify it. - Q: Is TLS 1.3 required? A: Not required, but faster and safer. TLS 1.2 is the minimum; 1.0/1.1 should be disabled. ### HTTP Header Checker URL: https://nuqti.com/seo-tools/http-header-checker (Arabic: https://nuqti.com/ar/seo-tools/http-header-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/http-header-checker?q=… Before any page content arrives, the server sends HTTP headers: the status code, content type, caching rules, compression, cookies, security policies and indexing instructions like X-Robots-Tag. Most SEO and speed problems leave a trace here. Nuqti requests the URL like a crawler, follows redirects, and lists every response header with a short explanation — plus quick verdicts on compression, caching, CDN and HTTP/3. What it measures: - All headers: Every header with a one-line explanation - Compression & cache: gzip/brotli and how long copies are kept - Server & CDN: The software and network serving the page - Response time: Time to first byte FAQ: - Q: How do I check the HTTP headers of a website? A: Enter the URL above. You'll see the status code and every response header the server returned. - Q: What is X-Robots-Tag? A: A header version of meta robots — it can noindex PDFs, images or whole sites. A stray 'noindex' here can drop pages from Google. - Q: How do I know if compression is on? A: Look for content-encoding: gzip or br (Brotli). No compression means larger, slower pages. - Q: Which caching header should I use? A: For static files: cache-control: public, max-age=31536000, immutable. For HTML: a short max-age or no-cache with an ETag. ### Security Headers Checker URL: https://nuqti.com/seo-tools/security-headers-checker (Arabic: https://nuqti.com/ar/seo-tools/security-headers-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/security-headers-checker?q=… Security headers are one-line instructions that tell browsers how to protect your visitors: force HTTPS (HSTS), block injected scripts (CSP), stop clickjacking (X-Frame-Options), stop file-type guessing and limit what leaks to other sites. Nuqti checks six key headers, weights them by impact, deducts for version leaks like 'X-Powered-By: PHP/7.4', and gives an A+ to F grade with an example value for each missing header. What it measures: - Grade: A+ to F from six weighted headers - Present: Headers you already send - Missing: What to add, with an example value - Leaks: Headers revealing software versions FAQ: - Q: Which security headers are most important? A: Strict-Transport-Security and Content-Security-Policy carry the most weight, then X-Frame-Options and X-Content-Type-Options. - Q: Do security headers affect SEO? A: Not directly — but HTTPS, safety and user trust do, and a hacked site loses rankings fast. - Q: Will a strict CSP break my site? A: It can. Start with Content-Security-Policy-Report-Only to see what would be blocked, then tighten. - Q: How do I add these headers? A: In your web server (Nginx add_header, Apache Header set), your CDN's rules, or your framework's config (e.g. Next.js headers()). ### Redirect Checker URL: https://nuqti.com/seo-tools/redirect-checker (Arabic: https://nuqti.com/ar/seo-tools/redirect-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/redirect-checker?q=… Redirects send visitors and search engines from one URL to another. Done right (one 301 hop), they pass ranking signals. Done wrong — long chains, temporary 302s for permanent moves, loops, or www and non-www both returning 200 — they waste crawl budget, slow users down and split your rankings. Nuqti follows the URL hop by hop like a crawler, timing each step, and also tests the four http/https × www/non-www versions to confirm they all land on one final address. What it measures: - Hops: Each step with its status code - Total time: Delay added by the redirects - Versions: http/https and www/non-www all agree? - Problems: Loops, chains and temporary redirects FAQ: - Q: 301 vs 302 — which should I use? A: 301 (or 308) for permanent moves — it passes ranking signals to the new URL. 302/307 only for genuinely temporary moves. - Q: How many redirects are too many? A: Aim for one hop. Google follows up to 10, but every hop adds delay and risk. - Q: What is a redirect loop? A: A → B → A forever. Browsers show 'too many redirects' and the page never loads. - Q: Should www redirect to non-www? A: Pick one version and 301 the other to it — it doesn't matter which, as long as it's consistent. ### Bulk HTTP Status Code Checker URL: https://nuqti.com/seo-tools/http-status-checker (Arabic: https://nuqti.com/ar/seo-tools/http-status-checker) Input: up to 20 URLs, one per line API: GET https://nuqti.com/api/public/v1/tools/http-status-checker?q=… Every URL answers with a status code: 200 means OK, 3xx means it redirects, 404/410 means the page is gone and 5xx means the server failed. Checking them in bulk is the fastest way to verify a migration, a list of backlinks or a sitemap sample. Paste up to 20 URLs (one per line). Nuqti checks them in parallel, follows redirects to the final page and summarises how many are OK, redirected, broken or failing. What it measures: - 2xx OK: Pages that load fine - 3xx: URLs that redirect, and where - 4xx / 5xx: Broken or failing pages - Speed: Response time per URL FAQ: - Q: What does a 404 status mean? A: Not found — the page doesn't exist. Redirect it (301) to the closest live page if it has links or traffic. - Q: What's the difference between 404 and 410? A: 410 Gone says the removal is deliberate and permanent; Google drops it slightly faster. - Q: Why does a URL return 403? A: The server refused access — often a firewall or bot protection. Check the page in a browser too. - Q: Can I check more than 20 URLs? A: Inside Nuqti, Site Audit crawls and checks every URL on your site automatically. ### Is It Down Right Now? URL: https://nuqti.com/seo-tools/website-down-checker (Arabic: https://nuqti.com/ar/seo-tools/website-down-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/website-down-checker?q=… When a site won't open, the problem can be on your side (Wi-Fi, DNS cache, a blocked network) or on the site's side (DNS failure, server down, application errors, expired certificate). Nuqti tests from outside your network in three layers — DNS answers from three providers, a TCP connection to the server, and loading the home page (retrying up to 3 times) — then tells you whether it's up, slow, blocked, erroring or down, and which layer failed. What it measures: - Status: Up, slow, blocked, error or down - DNS: Do 3 networks find the domain - Server: Does it accept a connection - Response time: How long the home page took FAQ: - Q: The site is up here but not for me — why? A: Try clearing your DNS cache, another browser, mobile data instead of Wi-Fi, or a different DNS (1.1.1.1). Your network or ISP may block it. - Q: What does 'blocked' mean? A: The server answered 403/429 — it's online but refuses automated checks (bot protection). It may still work in a normal browser. - Q: What does 'DNS failure' mean? A: No DNS server returns an address for the domain: expired domain, wrong nameservers or deleted records. - Q: Can Nuqti alert me when my site goes down? A: Yes — Nuqti monitoring checks your site on a schedule and alerts you. It's included in your free days. ### Website Hosting Checker URL: https://nuqti.com/seo-tools/website-hosting-checker (Arabic: https://nuqti.com/ar/seo-tools/website-hosting-checker) Input: a domain or hostname, e.g. mail.example.com API: GET https://nuqti.com/api/public/v1/tools/website-hosting-checker?q=… Want to know where a competitor hosts, where to send an abuse report, or which provider runs a site you're about to take over? The answer is spread across the site's IPs, nameservers, mail records and response headers. Nuqti combines them: it resolves the site's IPs and their network owner and country, detects a CDN in front (which hides the real host), and names the DNS and email providers. What it measures: - Hosting company: Who owns the network the site runs on - CDN: A proxy/CDN in front of the site - DNS provider: Who manages the domain's DNS - Email provider: Who handles the domain's email FAQ: - Q: Why does it say Cloudflare instead of the real host? A: The site uses a CDN/proxy in front of the origin server; the real host is hidden by design. - Q: Is the country where the server is? A: It's where the IP's network is registered; usually the data-centre country, except for CDNs and anycast networks. - Q: Can I find the hosting of any site? A: Yes, unless it's behind a CDN. You'll still see the DNS and email providers. - Q: How do I report abuse to a host? A: Use the network owner shown here — most have an abuse@ address listed for the IP range. ### Robots.txt Tester & Validator URL: https://nuqti.com/seo-tools/robots-txt-tester (Arabic: https://nuqti.com/ar/seo-tools/robots-txt-tester) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/robots-txt-tester?q=… robots.txt is the first file every crawler reads. One wrong line — a stray 'Disallow: /' after a redesign — can stop Google from crawling an entire site. AI crawlers like GPTBot and ClaudeBot follow it too, which decides whether AI assistants can read and cite your pages. Nuqti downloads the site's robots.txt, validates every line, and tests your URL for 10 major crawlers using Google's matching rules (longest match wins, Allow beats Disallow on a tie, * and $ wildcards). What it measures: - Verdict per bot: Allowed or blocked for 10 crawlers - Matching rule: The exact line that decides - Syntax issues: Lines crawlers will ignore - Sitemaps: Sitemap URLs declared in the file FAQ: - Q: Does robots.txt stop a page from appearing in Google? A: No — it stops crawling, not indexing. A blocked URL can still appear (without a snippet) if other sites link to it. Use a noindex tag to keep a page out. - Q: Should I block AI crawlers? A: It's your choice. Blocking GPTBot/ClaudeBot keeps content out of their training and answers, but also makes AI assistants less likely to cite you. - Q: Where must robots.txt be? A: At the root of each host: https://example.com/robots.txt. Sub-domains need their own file. - Q: What happens if robots.txt returns 5xx? A: Google treats a server error as 'don't crawl anything' for a while. A 404 means 'crawl everything'. ### XML Sitemap Validator URL: https://nuqti.com/seo-tools/sitemap-validator (Arabic: https://nuqti.com/ar/seo-tools/sitemap-validator) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/sitemap-validator?q=… An XML sitemap lists the pages you want search engines to find. A good sitemap holds only live, canonical, indexable URLs with honest lastmod dates; a bad one is full of redirects, 404s and URLs from the wrong host — and Google starts trusting it less. Enter a domain (Nuqti finds the sitemap from robots.txt) or a sitemap URL. Nuqti parses it — including sitemap indexes and gzip — validates the format and limits, charts lastmod freshness and checks the status of a sample of URLs. What it measures: - URLs: How many URLs, across how many files - Sample health: Status codes of a sample of URLs - Freshness: How recently pages were updated - Errors: Format, limits, wrong host FAQ: - Q: Where is my sitemap? A: Usually /sitemap.xml or /sitemap_index.xml, and it should be listed in robots.txt with a 'Sitemap:' line. - Q: What are the sitemap limits? A: 50,000 URLs and 50 MB (uncompressed) per file. Bigger sites use a sitemap index that lists several sitemaps. - Q: Should redirected or 404 URLs be in my sitemap? A: No. Only include the final, 200-status, canonical version of each page. - Q: Does lastmod matter? A: Google uses lastmod when it's consistently accurate. Don't set every page to today's date. ### Open Graph Checker & Link Preview URL: https://nuqti.com/seo-tools/open-graph-checker (Arabic: https://nuqti.com/ar/seo-tools/open-graph-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/open-graph-checker?q=… When someone shares your URL, social apps build a preview card from Open Graph meta tags: og:title, og:description and og:image. Missing or broken tags mean a bare link with no picture — and far fewer clicks. Nuqti loads the page like a social crawler, reads every OG tag, checks the image really loads and has the recommended 1200×630 size, and renders realistic previews for Facebook, LinkedIn, WhatsApp and Slack. What it measures: - Previews: Facebook, LinkedIn, WhatsApp & Slack cards - Image check: Loads? Size and aspect ratio - All tags: Every og: tag found - Score: Required & recommended tags present FAQ: - Q: What size should og:image be? A: 1200×630 px (1.91:1) works everywhere. Keep it under 5 MB, use an absolute https:// URL. - Q: I updated my tags but Facebook shows the old preview A: Social networks cache previews. Use Facebook's Sharing Debugger 'Scrape again' or LinkedIn's Post Inspector to refresh. - Q: Which OG tags are required? A: og:title, og:type, og:image and og:url. Add og:description and og:site_name for a richer card. - Q: Does Open Graph help SEO? A: Not as a ranking signal, but better previews earn more clicks and shares, which bring links and traffic. ### Twitter (X) Card Validator URL: https://nuqti.com/seo-tools/twitter-card-validator (Arabic: https://nuqti.com/ar/seo-tools/twitter-card-validator) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/twitter-card-validator?q=… X (Twitter) builds link cards from twitter: meta tags, falling back to Open Graph tags when they're missing. Since X retired its own card validator, the easiest way to check a card is to preview it before you post. Nuqti reads the twitter:card type, title, description and image (with OG fallbacks), checks the image loads and fits the card, and renders the card the way X shows it. What it measures: - Card preview: Your link as X shows it - Image: Loads, size and ratio - Tags: twitter: tags and OG fallbacks - Score: Required tags present FAQ: - Q: summary vs summary_large_image? A: summary shows a small square thumbnail; summary_large_image shows a wide image above the title — usually more clicks. - Q: Do I need twitter: tags if I have Open Graph? A: Only twitter:card is really needed; X falls back to og:title, og:description and og:image for the rest. - Q: What image size works best? A: 1200×628 for large cards (2:1 ratio shown), at least 144×144 for summary cards. Under 5 MB. - Q: Why doesn't my card show? A: The image may be blocked by robots.txt for Twitterbot, too big, or the page returns an error to the X crawler. ### Schema Markup Validator URL: https://nuqti.com/seo-tools/schema-markup-validator (Arabic: https://nuqti.com/ar/seo-tools/schema-markup-validator) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/schema-markup-validator?q=… Structured data (schema markup) tells search engines exactly what a page is about — a product with a price, a recipe, an article, an FAQ, a local business. It's what makes stars, prices and other rich results appear in Google, and it helps AI engines understand your content. Nuqti extracts every JSON-LD, Microdata and RDFa item, shows them as a tree, flags JSON syntax errors and missing required or recommended properties for common types, and tells you which Google rich results each item may qualify for. What it measures: - Items found: Every schema type, as a tree - Errors: Broken JSON and invalid items - Missing properties: Required & recommended fields absent - Rich results: Which enhancements each item can earn FAQ: - Q: JSON-LD, Microdata or RDFa? A: Google recommends JSON-LD: a script block separate from your HTML, easiest to add and maintain. - Q: Does schema improve rankings? A: Not directly — but rich results stand out and usually get a higher click-through rate. - Q: Why don't my stars show in Google? A: Valid markup makes a page eligible, not guaranteed. Google also needs to trust the site and the content must match the markup. - Q: Which schema types matter most? A: Organization, WebSite, BreadcrumbList on every site; Article, Product, FAQPage, HowTo, LocalBusiness, Event or Recipe depending on the page. ### Hreflang Tags Checker URL: https://nuqti.com/seo-tools/hreflang-checker (Arabic: https://nuqti.com/ar/seo-tools/hreflang-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/hreflang-checker?q=… hreflang tags tell Google which language or country version of a page to show each searcher — Arabic visitors get /ar/, UK visitors get /en-gb/. If they're broken, the wrong version ranks, or Google ignores them entirely. Nuqti reads hreflang from the HTML and HTTP headers, validates every language-region code, checks for x-default and a self-reference, then opens each alternate page to confirm it links back (Google ignores one-way hreflang). What it measures: - Languages: Every language/region version listed - Return links: Which alternates link back - Code errors: Invalid language or region codes - Score: Self-reference, x-default and consistency FAQ: - Q: What are return links? A: If page A lists B as an alternate, B must list A too. Without the return link Google ignores the pair. - Q: Do I need x-default? A: Recommended: it tells Google which page to show users whose language you don't target — usually a language selector or the main version. - Q: Is 'en-UK' valid? A: No — the region code for the United Kingdom is GB, so use en-GB. Language codes are ISO 639-1, regions ISO 3166-1. - Q: Should hreflang URLs be canonical? A: Yes. Each alternate must be the canonical, indexable 200 version of that page. ### Canonical Tag Checker URL: https://nuqti.com/seo-tools/canonical-checker (Arabic: https://nuqti.com/ar/seo-tools/canonical-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/canonical-checker?q=… rel=canonical tells search engines which URL is the main version of a page when the same content is reachable at several addresses (with parameters, http/https, www, sorting). It consolidates ranking signals onto one URL. Nuqti reads the canonical tag and HTTP Link header, checks they agree, then requests the canonical URL itself — it must return 200, not redirect, not be noindex and not point somewhere else again. What it measures: - Canonical URL: The version this page declares - Target status: Does the canonical URL return 200 - Conflicts: Tag vs header, noindex, multiple tags - Self or other: Points to itself or to another page FAQ: - Q: Should every page have a canonical tag? A: Yes — a self-referencing canonical on every indexable page is best practice and protects against parameter duplicates. - Q: Is canonical a directive? A: It's a strong hint. Google may choose another canonical if signals conflict (sitemaps, internal links, redirects). - Q: Can I canonical to another domain? A: Yes, for syndicated content. The other page must have the same content. - Q: Canonical + noindex together? A: Avoid it: it sends mixed signals. Use one or the other. ### Google SERP Preview Tool URL: https://nuqti.com/seo-tools/serp-preview (Arabic: https://nuqti.com/ar/seo-tools/serp-preview) Input: a keyword API: GET https://nuqti.com/api/public/v1/tools/serp-preview?q=… Your title tag and meta description are your ad in Google. Google truncates titles at about 600 pixels on desktop (not a fixed number of characters — 'W' is far wider than 'i'), and descriptions at about 920 pixels on desktop and fewer on mobile. Nuqti measures your text in pixels using the same font Google uses, shows where the '…' will appear on desktop and mobile, and renders the full result card so you can polish it before publishing. What it measures: - Desktop & mobile: Your result as Google shows it - Pixel width: Title and description length in px - Cut-off: Exactly where the text gets truncated - Character count: Characters and words FAQ: - Q: How long should a title tag be? A: Up to about 600 px — roughly 50–60 characters. Put the main keyword near the start. - Q: How long should a meta description be? A: About 150–160 characters (920 px) on desktop; the first ~120 characters matter most for mobile. - Q: Why does Google show a different title? A: Google rewrites titles that are too long, stuffed with keywords, or don't match the page. Keep them descriptive and unique. - Q: Does the meta description affect rankings? A: No, but a compelling one raises click-through rate. ### Keyword Density Checker URL: https://nuqti.com/seo-tools/keyword-density-checker (Arabic: https://nuqti.com/ar/seo-tools/keyword-density-checker) Input: plain text (up to 20,000 characters) API: GET https://nuqti.com/api/public/v1/tools/keyword-density-checker?q=… Keyword density is how often a word or phrase appears compared to the total word count. There is no magic percentage — but density reveals what a page is really about, shows keyword stuffing, and spots topics you forgot to mention. Nuqti strips menus and code, counts single words and 2- and 3-word phrases (ignoring stop words in English and Arabic), and — if you give a focus keyword — shows its density and whether it appears in the title and first paragraph. What it measures: - Top words: Most frequent meaningful words - Phrases: Top 2- and 3-word phrases - Focus keyword: Density and placement - Word count: Total words analysed FAQ: - Q: What is a good keyword density? A: There's no ideal number. Write naturally; if your main keyword is above ~3% the text probably reads as stuffed. - Q: Does Google use keyword density? A: Not as a target. Google understands topics and synonyms — covering the subject well matters more than repetition. - Q: What are stop words? A: Very common words like 'the', 'and', 'في', 'من' — they're excluded so the meaningful terms stand out. - Q: Does it work for Arabic? A: Yes — Arabic text is tokenised and Arabic stop words are filtered too. ### H1 & Heading Structure Checker URL: https://nuqti.com/seo-tools/heading-checker (Arabic: https://nuqti.com/ar/seo-tools/heading-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/heading-checker?q=… Headings are the outline of a page. A clear H1 that states the topic, followed by H2 sections and H3 sub-points, helps readers scan, helps screen readers navigate and helps search engines and AI understand the structure. Nuqti maps every H1–H6 as an indented tree, counts each level and flags common problems: no H1, several H1s, jumps like H2 → H4, empty headings and headings that are too long. What it measures: - Outline: Every heading as an indented tree - Counts: How many H1, H2, H3… - Issues: Missing H1, skipped levels, empty headings - Score: How clean the structure is FAQ: - Q: Can a page have more than one H1? A: HTML allows it and Google copes, but one clear H1 is still the cleanest structure. - Q: Should the H1 match the title tag? A: They should share the main topic and keyword, but they don't have to be identical. - Q: Is skipping heading levels bad? A: Jumping from H2 to H4 confuses screen readers and the outline. Use levels in order. - Q: Do headings affect SEO? A: They help Google understand the page sections and can be shown as jump links and featured snippets. ### Website Technology Checker URL: https://nuqti.com/seo-tools/website-technology-checker (Arabic: https://nuqti.com/ar/seo-tools/website-technology-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/website-technology-checker?q=… Every website leaves fingerprints: script names, HTML patterns, cookies, headers and meta tags reveal the CMS (WordPress, Shopify, Wix…), the framework (Next.js, Nuxt, Laravel…), analytics and ad tags, CDN and server. Nuqti loads the page and matches 120+ signatures across HTML, scripts, headers and cookies, grouping the results by category with the evidence for each detection and the version when visible. What it measures: - Technologies: Everything detected, grouped by category - CMS & framework: What the site is built on - Analytics & marketing: Tracking, ads and chat tools - Evidence: Why each technology was detected FAQ: - Q: How do I know what CMS a website uses? A: Enter its URL — the CMS appears at the top of the results with the evidence (e.g. /wp-content/ paths for WordPress). - Q: Why wasn't a technology detected? A: Some sites hide fingerprints, render everything server-side or load tools only after consent. Detection is based on what the page exposes publicly. - Q: Is this like BuiltWith or Wappalyzer? A: Yes — the same kind of fingerprinting, free and without installing an extension. - Q: Can I see a site's hosting too? A: Use Nuqti's hosting checker for the hosting company, IP and DNS provider. ### Web Page Size Checker URL: https://nuqti.com/seo-tools/page-size-checker (Arabic: https://nuqti.com/ar/seo-tools/page-size-checker) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/page-size-checker?q=… Page weight drives load time — especially on mobile data. The median web page is now over 2 MB, and a few oversized images or scripts are usually responsible. Nuqti downloads the HTML and every script, stylesheet, image and font it references, measures each one (compressed and uncompressed), and breaks the total down by type with the heaviest files listed first. What it measures: - Total size: Everything the page loads, in KB/MB - By type: HTML, CSS, JS, images, fonts - Heaviest files: Where the weight comes from - Requests: How many files the browser must fetch FAQ: - Q: What is a good page size? A: Under 1 MB is fast; 1–3 MB is typical; above 3 MB will feel slow on mobile. - Q: How do I reduce page size? A: Compress and resize images (WebP/AVIF), remove unused JavaScript, enable gzip/brotli and lazy-load below-the-fold media. - Q: Why is the transferred size smaller? A: Text files are compressed in transit (gzip/brotli). The browser still has to parse the full uncompressed size. - Q: Does it include lazy-loaded resources? A: Resources referenced in the HTML are included; ones injected later by JavaScript may not be. ### llms.txt Generator URL: https://nuqti.com/seo-tools/llms-txt-generator (Arabic: https://nuqti.com/ar/seo-tools/llms-txt-generator) Input: a public URL, e.g. https://example.com/page API: GET https://nuqti.com/api/public/v1/tools/llms-txt-generator?q=… llms.txt is a proposed standard: a short Markdown file at the root of your site that gives large language models a clean summary and a curated list of your most important pages — easier for them to read than full HTML. Nuqti checks whether you already have one, reads your home page, navigation and sitemap, picks the key pages, and writes an llms.txt in the right format that you can copy and upload to /llms.txt. What it measures: - Your llms.txt: A ready file to copy or download - Pages picked: The key pages included - Existing file: Whether you already publish one - AI access: Do AI crawlers have access in robots.txt FAQ: - Q: Do AI engines use llms.txt? A: It's an emerging standard; several AI tools and documentation platforms read it. It's cheap to add and doesn't affect Google rankings. - Q: Where do I put the file? A: Upload it to the root: https://yourdomain.com/llms.txt, served as plain text. - Q: What's the format? A: An H1 with the site name, a > blockquote summary, then H2 sections with Markdown link lists: - [Title](url): description. - Q: Does it replace robots.txt? A: No — robots.txt controls access; llms.txt only guides AI to your best content. ### Word Counter URL: https://nuqti.com/seo-tools/word-counter (Arabic: https://nuqti.com/ar/seo-tools/word-counter) Input: plain text (up to 20,000 characters) API: GET https://nuqti.com/api/public/v1/tools/word-counter?q=… Whether you're hitting an essay limit, sizing a blog post for SEO or trimming a speech, you need an exact word count — and a sense of how long the text takes to read. Nuqti counts words, characters (with and without spaces), sentences and paragraphs, estimates reading and speaking time, scores readability for English text and lists the words you use most. Arabic is fully supported. What it measures: - Words: Total words in your text - Characters: With and without spaces - Reading time: Silent reading and speaking - Readability: How easy the text is to read FAQ: - Q: How long should a blog post be? A: Long enough to fully answer the search query. For competitive topics that's often 1,200–2,500 words — check what ranks with Nuqti's SERP checker. - Q: How is reading time calculated? A: At about 238 words per minute (average silent reading) and 150 for speaking. - Q: Does it count Arabic words correctly? A: Yes — words are split on spaces and punctuation, including Arabic punctuation. - Q: Is my text saved? A: No. The text is processed for the count and not stored. ### Character Counter URL: https://nuqti.com/seo-tools/character-counter (Arabic: https://nuqti.com/ar/seo-tools/character-counter) Input: plain text (up to 20,000 characters) API: GET https://nuqti.com/api/public/v1/tools/character-counter?q=… Almost every platform has a character limit: about 60 for a Google title, 155 for a meta description, 280 for a post on X, 2,200 for an Instagram caption, 160 for an SMS. Nuqti counts every character (emoji and Arabic letters correctly counted as one), with and without spaces, plus letters, digits, words and lines — and shows a bar for each common limit so you know at a glance what fits. What it measures: - Characters: With and without spaces - Words & lines: Words, sentences and lines - Limits: Fits Google, X, Instagram, SMS? - Breakdown: Letters, digits, spaces and symbols FAQ: - Q: Do spaces count as characters? A: On most platforms yes. You'll see both counts — with and without spaces. - Q: How are emoji counted? A: As one visible character each here. Some platforms (like X) count certain emoji as two. - Q: What is the SMS limit for Arabic? A: 70 characters per message (Unicode), versus 160 for plain Latin text. - Q: Is my text saved? A: No. It's processed for the count and not stored. ## Metrics glossary - Nuqti Authority (0-100): a website's position among ~133 million sites ranked by how close they are to the rest of the web through links; log-scaled so 50 is far stronger than 25. - Keyword Difficulty (0-100): how hard it is to reach Google's top 10, from the authority and links of the pages ranking now. <10 very easy, <30 easy, <50 medium, <70 hard. - Organic traffic: estimated monthly clicks from Google = sum over ranking keywords of search volume × click-through rate at that position. - Traffic value: what that traffic would cost as Google Ads (clicks × CPC).
