Why it matters

Decide what changes next

Read this finding as evidence about the affected page, not as a verdict on the whole site. A Review finding needs a decision; a Blocked finding should be addressed before the page moves forward. Coverage findings mean the check is incomplete, not that the page passed.

How to resolve it

Use a valid canonical URL or remove the field until the intended canonical is known.
