About Canonical URL Checker

The Canonical URL Checker helps you confirm whether a page is self-canonical, whether duplicate URLs point to the same preferred destination, and whether noindex directives are getting in the way.

How to use

Enter the main page URL you want to validate.
Optionally add a second URL to compare a duplicate or parameterized version.
Review the canonical target, final resolved URL, and indexability notes.
