Check whether a page points search engines to the right canonical URL before you build backlinks or submit it to directories.
Canonical URL report
Your canonical URL report will appear here.
Enter a public page URL to check if search engines are pointed to the right canonical version.
A canonical tag tells search engines which URL should be treated as the main version of a page. This helps reduce duplicate URL confusion from tracking parameters, trailing slashes, http and https variants, and copied landing pages.
The checker fetches the live page, reads the canonical link tag, compares it with the final URL, and flags missing, cross-domain, http, and mismatched canonical signals.
Directory listings and backlinks should point authority to the correct page. A clean canonical setup helps those external signals support the right URL.
Use this workflow to get more useful output from the tool and make the page stronger before you share, launch, or submit your startup to directories.
