More about the Canonical Tag Checker
A canonical tag that's simply missing is a problem, but a canonical tag that's present and pointing at the wrong URL entirely is a worse one, quietly telling Google not to index the actual page at all because a templating bug pointed its canonical at an old URL, a competitor's page, or something completely unrelated, an error that stays invisible until search traffic for that page mysteriously disappears. This tool checks whether a webpage has a canonical tag and confirms exactly which URL it's actually pointing at, catching both a missing tag and one that's pointing somewhere it shouldn't. Useful for confirming a page's canonical tag actually points at itself rather than an unrelated URL, catching a templating bug that's silently sending a canonical tag to the wrong page, or auditing a site's canonical tags after a URL structure change to confirm nothing broke.
Check if a webpage has a canonical tag and see which URL is set as the preferred version. The Canonical Tag Checker is one of 900+ free developer tools on Toolblip - all open to use without a signup.
