SEO Page Inspector

Instant on-page SEO analysis: meta tags, headings, images, links, Open Graph, hreflang, HTTP status & sitemap checks.

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 — Title (with length check), Description, Keywords, Canonical, Robots tag, Author, Publisher, Lang, Charset, plus 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. 🏷️ Headers — Every H1–H6 heading in document order, indented by level and color-coded, so you can audit heading structure at a glance. 🖼️ Images — Totals for images without ALT and without TITLE, with thumbnails and per-image flags. 🔗 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). 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 / multilingual — Lists all language alternates and tells you whether an x-default is defined. 🛠️ Tools — Quick links to robots.txt and sitemap.xml, detected JSON-LD structured-data types, and one-click shortcuts to 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. 🎯 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. Why you'll like it One click, instant — full page audit the moment the popup opens. Private by design — everything runs locally in your browser. No tracking, no analytics, no account. See problems, not just data — color-coded warnings, on-page highlighting, and grouped issue lists. Goes further than most — built-in HTTP link checking and sitemap validation, not just meta-tag readouts. Clean, modern interface — organized tabs, light/dark themes, easy to read. Free. Perfect for SEO specialists, developers, content editors and site owners doing quick on-page audits. Notes for when you paste this in: The store summary field is separate from the description field — use the short line for summary, the rest for description. One honest caveat in the copy: redirects are shown as 3xx (not the exact 301 vs 302) — the wording above already reflects that, so it stays accurate. Want a matching privacy justification blurb for the <all_urls> permission (the review team asks for one) and a single-purpose statement? I can draft those too.
