Instantly inspect a page's SEO: meta title, description, canonical, Open Graph, Twitter cards, headings, robots and more.

SEO Meta Inspector shows you everything that matters for a page's search-engine optimisation in one click — no sign-up, no tracking, no data leaves your browser. Click the toolbar icon on any web page to instantly see: • Title tag and meta description with live length checks • Canonical URL and robots directives (index/noindex, follow/nofollow) • Open Graph tags with a live preview image • Twitter / X card tags • Heading structure — H1, H2, H3 counts, with warnings • Word count, image count and images missing alt text • Internal vs external link counts • Structured data (JSON-LD), hreflang, language, charset and viewport One-click "Copy" exports the full report as plain text. Privacy-first: it only reads the page you're actively viewing when you click, sends nothing to any server, and stores no data.
