Crawling and indexing tool

Canonical Tag Checker

See which canonical URL a live page declares and how it relates to the final URL. The result shows evidence for review without assuming every missing or cross-domain canonical is wrong.

FreeNo loginNo data stored
We follow a bounded redirect path and inspect canonical elements in the final HTML. Public HTTP and HTTPS URLs only; private networks and non-standard ports are blocked.
Result quality guidance

Template QA

Confirm that a page template emits one deliberate canonical after deployment.

Migration review

Compare redirected URLs with the canonical on the final destination.

Syndication check

Inspect a cross-domain canonical before deciding whether it is intentional.

What it checks

Use the result as evidence, not a score.

  • Requested and final URL after bounded redirects
  • Every canonical link found in the final HTML
  • Resolved canonical URL and its relationship to the final page
  • Final HTTP response
What it cannot check
  • Google’s selected canonical for the page
  • Whether consolidation is intentional without business context
  • Canonical consistency across the whole website
How it works

Input, inspect, improve, verify.

The tool processes what you enter, shows a plain-language result, and gives you a safer next step. Make the change on your website, deploy it, then test the live page again.

Popular use cases

Useful before and after publishing.

Pro tips

Small checks that prevent avoidable mistakes.

  1. Use absolute canonical URLs and keep exactly one declaration in the final HTML.
  2. Compare the canonical with the final URL after redirects, not only the address you entered.
  3. Do not remove a cross-domain canonical until the publishing or syndication intent is confirmed.
  4. Use Search Console for Google-selected canonical evidence on a verified property.
Common issues and solutions

What to review when the result looks wrong.

No canonical is found

This can be acceptable when the page has no equivalent URL. Review the wider URL pattern before adding one.

Several canonicals appear

Check templates, plugins, and JavaScript for competing declarations, then keep one intentional value.

Canonical and final URL differ

Confirm whether this is deliberate consolidation, a migration remnant, or an incorrect template value.

Frequently asked questions

Short answers before you make a change.

Does a canonical force Google to use that URL?

No. A canonical is a strong hint. Google can select another URL when other signals conflict.

Is a missing canonical always an SEO problem?

No. It depends on whether equivalent URL versions can exist and how the site manages them.

Can this show Google’s selected canonical?

No. That requires Google Search Console access for a verified property.
