Free Meta Tag Viewer & SEO Auditor
Audit any website's metadata and SEO tags in seconds. View Open Graph, Twitter cards, and standard meta tags to ensure your site is social-ready.
Built With Care
“Metadata is fetched through a Netlify serverless function that acts as a CORS-safe proxy, with a 20-second abort timeout and retry logic for slow sites. The audit then scores the page against SEO best practices: titles of 30 to 60 characters, descriptions of 120 to 160 characters, and the presence of Open Graph, Twitter Card, viewport, and canonical tags.”
