Page Audit — On-Page SEO

Page Audit gives you an instant, on-page SEO breakdown of any web page — in one click, entirely inside your browser. No account, no sign-up, no data ever leaves your machine. Click the toolbar icon and Page Audit reads the page you're on and scores it out of 100, then breaks the result into three tabs: OVERVIEW • Live 0–100 on-page SEO score with pass / warn / fail counts • On-page elements — title tag and meta description (with length checks) and meta robots • Heading summary — H1 / H2 / H3 / H4+ counts with a structure check • Content depth — word count, image count, link count, and page language • Published / updated dates when the page exposes them HEADINGS • The full H1–H6 outline, indented by level • Automatic "skipped heading level" detection • Optionally include visually-hidden and ARIA (role="heading") headings SEO • Four category scores — Meta & tags, Indexability, Social, Accessibility • A detailed pass/warn/fail checklist: title, meta description, meta robots, canonical URL, viewport, language, Open Graph, Twitter card, structured data (JSON-LD), images missing alt text, and HTTPS DOCK IT AS A SIDE PANEL Prefer to keep the audit open while you work? Turn on "Open results in side panel" in Settings and Page Audit opens in Chrome's docked side panel instead of the popup — and re-scans automatically as you browse from page to page. HEADING OVERLAY Flip on the heading outline overlay to highlight every H1–H6 directly on the page, color-coded by level — great for spotting structure problems at a glance. MAKE IT YOURS • Auto-run the audit on load, or run it manually • Show or hide any section (on-page elements, headings, content depth, content stats, category scores) • Everything is remembered via Chrome sync settings PRIVATE BY DESIGN Page Audit runs 100% locally. It does not collect, store, or transmit your browsing data, and it makes no network calls. No login, no tracking, no usage limits — free and unlimited. Built by Ibrahim Jaber.
