Canonical Tag Checker

Check whether a webpage has a canonical tag, if it matches the final URL, and whether multiple canonical tags exist.

Check Canonical URL

What is a Canonical Tag?

A canonical tag tells search engines which URL is the preferred version of a page. It helps reduce duplicate content issues and consolidates ranking signals to the correct URL.

  • Use one canonical tag per page.
  • Use absolute URLs.
  • Avoid canonicalizing to redirected or blocked pages.
  • Make sure the canonical URL is indexable.
