Canonical URL Checker
To check a canonical URL, enter a page address. ClickZM fetches it, reads the rel=canonical link and HTTP Link header, and reports whether the canonical is present, absolute, self-referencing, reachable with a 200 status, and consistent with redirects.

Canonical URL Checker: questions people ask
Should every page have a canonical tag?
Yes. A self-referencing canonical on each page prevents duplicates from URL parameters, tracking codes and http/https or www variations.
Is a canonical a directive?
No. Google treats it as a strong hint and may pick a different canonical if signals disagree, for example if the canonical URL redirects.
How does the Canonical URL Checker work?
Browsers cannot open raw network connections or read other websites directly, so ClickZM's server performs the check and returns the result. It blocks private and local addresses and does not store what you look up.
Is the Canonical URL Checker free?
Yes. The Canonical URL Checker is free with no signup, no watermark and no daily limit.
