Meta Tag Analyzer

Analyze SEO, Open Graph, Twitter and technical meta tags on any page.

Meta Tag Analyzer audits the meta tags and SEO signals of any page — locally, in your browser. Click the icon on any tab to get: • A 0–100 score and A–F grade • 37 checks across SEO, Technical, Open Graph, Twitter Cards, Structured Data (JSON-LD / schema.org) and On-Page Content (H1, headings, image alt, hreflang) • "Top fixes" ranked by ranking impact • A plain-language explanation of why each issue matters • Copy-ready HTML snippets for every fix • A one-click Markdown report to paste into any tool or AI assistant • A "Share preview" tab — see how the page looks when shared on Google, X, Facebook and WhatsApp • Consistency checks that flag og:image, twitter:image and favicon tags that are set but fail to load (broken link or 404) The score summary stays pinned in the header as you scroll — grade, score and passed / warning / missing counts are always visible. Hover any metric for a quick explanation of what it means. Everything runs on your device. No data is collected, and the address of the page you analyze never leaves your browser. To render share previews and verify that social images load, your browser fetches only that page's own og:image, twitter:image and favicon — the same assets the site already serves. No other network requests are made.
