Check Open Graph tags, Twitter Cards, meta description, favicon, and hreflang for any URL. Preview how your page looks when shared on Facebook, X/Twitter, LinkedIn, and Slack.
Enter a URL to inspect its Open Graph and social metadata
Open Graph (OG) tags are HTML meta elements that control how your pages appear when shared on Facebook, LinkedIn, Slack, and iMessage. Without them, platforms guess at your title, image, and description - often with poor results. This tool fetches any public URL and audits its OG tags, Twitter Card metadata, favicon declarations, and hreflang alternate links in one pass.
The three required OG tags are og:title (under 60 chars), og:description (150-200 chars), and og:image (at least 1200x630px). Twitter Card tags override OG equivalents on X/Twitter - if absent, X falls back to the OG values, so separate Twitter tags are only needed when you want a different appearance there. The favicon section shows all link rel=icon declarations found in the HTML head plus the /favicon.ico fallback path every browser tries automatically.
The hreflang section reports link rel=alternate hreflang tags, which tell search engines which language or region a page targets. Correct hreflang setup prevents duplicate content penalties when the same content exists at multiple URLs for different locales. The meta description is audited separately - it controls the Google search snippet and should be 120-160 characters.
