Enter a URL to find its rel="canonical" tag and the address it points to.

What is a canonical URL?

A canonical tag (<link rel="canonical">) tells search engines which URL is the main version of a page when the same content is reachable at several addresses - with or without www, with tracking parameters, or with trailing slashes. It consolidates ranking signals on one URL.

How to check a canonical tag

Enter the page URL or domain in the box above.
Click Check Canonical.
Confirm a canonical tag exists and points to the preferred, indexable URL.
Make sure it uses https and the same host version (www or not) that the site redirects to.

Related checks

To check whether the page can be indexed, use the Indexability Checker.
For language variants, use the Hreflang Checker.

Every indexable page should point its canonical tag at itself, with the same https and www version you use everywhere else. JustChecker alerts you if canonicals start pointing somewhere unexpected after a site change.
