Frequently asked questions

What is a canonical tag?

It is a link element in a page’s head that identifies the preferred URL for that content. It helps search engines understand similar or duplicate pages.

Why are canonical tags important for SEO?

They communicate your preferred version when similar URLs exist, helping search engines consolidate duplicate pages and their signals.

Should every page have a canonical tag?

An explicit canonical is often useful, but not required for every page. Point it to the preferred version of the same or substantially similar content.

What is a self-referencing canonical?

It points to the page’s own URL. This is a common, normal way to identify that URL as the preferred version.

Can a canonical tag point to another domain?

Yes. Cross-domain canonicals can be intentional for equivalent content on another domain. Review the destination; a different domain is not automatically an error.

Is a relative canonical URL valid?

Relative URLs can be resolved, but absolute URLs are recommended to reduce ambiguity. This checker shows the absolute URL resolved by the Fetch Core.

What happens if a canonical URL redirects?

Prefer linking directly to the intended final canonical URL. This checker follows redirects for the page you submit, but does not separately fetch the canonical destination.

Does a canonical tag guarantee Google will index that URL?

No. A canonical is a signal, not an absolute directive or an indexing guarantee. Google may choose another URL based on other signals.
