Clicks arriving at a page that canonicalises elsewhere

What this means

Search Console attributes clicks to this URL while its rel=canonical nominates a different address, so the page is winning traffic under an identity it has disowned. Google usually honours the canonical eventually, at which point the rankings either transfer to the target or are lost in the handover. The check needs at least one click, and it only fires where the canonical resolves to a valid absolute http or https URL that differs from the page's own normalised URL — a canonical that cannot be parsed is ignored here rather than guessed at.

How to fix it

Decide which URL should own the traffic. Where it is this one, point the canonical at itself. Where it is the nominated target, confirm the target covers the same intent and 301-redirect this URL to it, so the consolidation is explicit rather than left to Google's judgement.

Fix effort

This check needs review: the change can be drafted for you, but a person has to approve the wording or choose the target before it ships.
