What the tool does
Canonical URL Checker helps users compare a page URL and canonical URL for common canonicalization issues.
When to use it
Use it before publishing or auditing pages that may have duplicate URLs, tracking parameters, or canonical tag issues.
How to read the result
Read the result as a review signal for Canonical URL Checker. Warnings or counts indicate items to inspect, not automatic proof that a page is correct or incorrect.
Limitations
Canonical URL Checker cannot see private dashboards, authenticated pages, blocked crawlers, or every search engine decision. Use it alongside browser checks and official platform tools.
Privacy / safety note
Avoid entering private drafts, embargoed URLs, or confidential campaign data unless you are comfortable reviewing it in your browser.
