Free SEO diagnostic

Meta Tag Checker

Inspect a page's title, description, indexing directives, canonical URL, viewport, language, Open Graph, Twitter Card, favicon and web app metadata.

Check page metadata

Fetching works only when the remote site permits cross-origin browser access. Pasting the page source is the reliable fallback.


Search engines may rewrite titles and descriptions, ignore unsupported metadata, or interpret directives differently. This checker reports what appears in the supplied HTML; it does not confirm what a crawler ultimately indexed.
