SEO Page Inspector — Meta Tags, Headings & Schema Audit

On-page SEO audit in one click: title, meta, headings, canonical, hreflang, Open Graph and schema. No account, no telemetry.

SEO Inspector — see everything that matters for SEO on any page, in one click. Open the popup on any website and instantly get a clean, organized breakdown of the page's on-page SEO — no sign-up, no accounts, no data leaving your browser. What it does 📋 Summary — A clear Indexability verdict (Indexable / Not indexable, with the exact reasons: robots meta, X-Robots-Tag, canonical). Plus Title (with length check), Description, Canonical, Robots tag, Author, Publisher, Lang, Charset, and live counts of H1–H6, images and links. Missing or problematic tags are flagged with color-coded status dots (green / amber / red) so issues jump out immediately. One-click copy buttons for Title, Description and Canonical. 🚩 Issues — Every problem found across all tabs in one prioritized list: critical first, then warnings. Click any issue to jump straight to the tab that explains it. 🏷️ Headers — Every H1–H6 heading in document order, indented by level and color-coded, so you can audit heading structure at a glance. Flags skipped levels (H2 → H5), empty heading tags and a first heading that isn't an H1. 📝 Content — Full text analysis: total and unique words, unique-word share, water (redundancy), stop words, characters, sentences and average sentence length, plus Flesch Reading Ease, Flesch–Kincaid grade and Gunning Fog scores. Top words and 2- and 3-word phrases show frequency, density and whether each one appears in your Title, Description and H1. ⚡ Speed — The whole load waterfall in numbers: total load time, DNS lookup, TCP connection, TLS handshake, request and response, DOM interactive / content loaded / complete, transfer size and request count — each with an OK / Slow / Bad verdict. Plus live Core Web Vitals (LCP, INP, CLS, FCP, TTFB), layout-shift stability and every resource that took longer than 300 ms. 🖼️ Images — Totals for images without ALT and without TITLE, with thumbnails and per-image flags. Check images on demand to find broken files and oversized downloads. 🔗 Links — Two views: • General — totals, internal vs. external, unique links, nofollow, anchors, empty hrefs, plus an expandable "Issues" list grouping links that are missing a title or have an empty href. • Link checker — probe every link's HTTP status and highlight redirects (3xx) and errors (404 / 4xx / 5xx). Filter by All / Internal / External / Nofollow / Issues, and click any result to jump straight to that link on the page. 📣 Social — Open Graph and Twitter Card tags with image preview, exactly as social networks and messengers will see them. 🌍 Hreflang — A dedicated tab listing all language alternates and telling you whether an x-default is defined. 🌐 Domain — Domain age, creation, update and expiry dates and registrar via RDAP (modern WHOIS), plus live DNS records (A, AAAA, NS, MX, TXT) over DNS-over-HTTPS. 🛠️ Tools — Quick links to robots.txt, sitemap.xml, llms.txt and llms-full.txt (detects if they exist), detected technologies and JSON-LD structured-data types, HTTP response headers, and one-click shortcuts to Google Search Console, PageSpeed Insights, Rich Results Test, Facebook Debugger and the W3C validator. Includes a Sitemap Validator that fetches your sitemap (and sub-sitemaps) and lists any URLs returning redirects or errors. 📄 Export & reports — Download the full audit as JSON or CSV, or open a clean, printable PDF report. 🎯 On-page highlighting — Automatically outlines every heading (with its H1–H6 label) and every image missing ALT/TITLE right on the page, with a master toggle to turn it on or off. 🌗 Light & dark theme — Switch instantly; your choice is remembered. 🗣️ 20 languages — The whole interface speaks English, Українська, Русский, Español, Deutsch, Français, Português, Italiano, Polski, Nederlands, Türkçe, Svenska, Bahasa Indonesia, Tiếng Việt, हिन्दी, বাংলা, ไทย, 한국어, 日本語, العربية and اردو, with full right-to-left support.
