Canonical Tag Auditor

Check which URL a page names as canonical, whether that URL holds up, and whether every spelling of the address redirects to it.

What it does

Checks your canonical tag against everything else your site says about which URL is the real one: redirects, robots.txt and every spelling of the address. Google weighs all of them together, so a correct tag can still lose.

How to use it

  1. Paste the page you care about.
  2. Fix the redirects first, then the tag, and run it again.

Good to know

  • Google ranks a redirect above rel="canonical", so when the two disagree, the redirect wins.
  • We read the HTML before any script runs, so a canonical added by JavaScript won’t show here.
  • If a firewall turns us away, that says nothing about Googlebot. URL Inspection in Search Console shows what Google gets.

Your sitemap and internal links have to agree too, and checking them takes a crawl. Technical SEO Foundations explains how.
