What this canonical tag checker checks
- Whether a canonical link exists
- How many canonical tags appear
- The resolved absolute canonical URL
- Whether the canonical is self-referencing
How to read the result
Most indexable pages should declare one canonical URL. A canonical pointing elsewhere can be intentional for duplicate content, but an accidental mismatch may cause search engines to index a different page.
How to use it
- Enter the complete public HTTPS URL you want to inspect.
- Select the check button and wait for the live response.
- Review the result and correct any issue at the website or hosting provider.
- Run the checker again to confirm the public response changed.
Common questions
Is a self-referencing canonical required?
It is not strictly required, but it provides a clear preferred URL and helps consolidate URL variations.
Can a page have two canonical tags?
It can, but conflicting canonical declarations may be ignored. Use one clear canonical in the HTML head.
Does a canonical force Google to index that URL?
No. Canonicals are strong hints. Search engines may choose another URL when other signals conflict.
