What the check does

The preflight reads the canonical link detected on the public page. A self-canonical supports the submitted URL; a canonical pointing elsewhere suggests that another version is preferred.

How to interpret the result

Canonical tags are signals rather than absolute commands. Redirects, sitemaps, internal links, duplicate content, and search-engine selection should support the same preferred URL.

Next step

Use the duplicate and canonical guide to align all signals before submitting again.
