Create a canonical link element from a preferred absolute page URL, optionally normalize it to HTTPS, and compare it with a current URL you provide.

Frequently asked questions
How should I use this result?
A canonical tag is a hint about a preferred URL among duplicate or similar pages. Keep it consistent with redirects, internal links and sitemap URLs; this tool does not fetch either page.
Does this tool send a message or API request?
No message or API request is sent automatically. Any external action requires an explicit user click.
