FAQ

Información útil

How do I use Canonical Tag Checker?

1. Paste page HTML: Paste source or rendered HTML. Enter the page URL for comparison. 2. Review the findings: Inspect missing or multiple canonical tags, absolute URLs and mismatches. 3. Check the live destination: Verify redirects, HTTP headers and indexing separately.

Does this fetch the page?

No. Only pasted HTML is checked. HTTP Link headers and the canonical selected by Google are outside this check.

Is a different canonical always wrong?

No. A duplicate page may point to an equivalent preferred page. Verify that the choice is intentional.
