Canonical Loop or Chain Detected
Canonical tags form a loop (A points to B, B points to A) or a chain (A points to B, B points to C). Search engines may not follow multi-hop canonical chains, leaving ranking signals diluted.

- You want a repeatable re-check path after shipping the change.
What this issue is
Canonical tags form a loop (A points to B, B points to A) or a chain (A points to B, B points to C). Search engines may not follow multi-hop canonical chains, leaving ranking signals diluted.
Why it matters
Canonical tags form a loop (A points to B, B points to A) or a chain (A points to B, B points to C). Search engines may not follow multi-hop canonical chains, leaving ranking signals diluted. This affects how clearly search engines understand the page and how persuasive it looks in search results.
How we detect it
- FreeSiteAudit flags this issue when the rule for CRAWL-CANONICAL-LOOP-001 fails and the page evidence points to Nav crawl.
- You can usually confirm this by checking the page source or the relevant page settings inside your CMS.
Evidence examples
How to fix it
- 1Ensure every canonical tag points directly to the final preferred URL
- 2Break loops by choosing a single canonical target for each set of duplicate pages
- 3Avoid chains of more than one hop in canonical references
How to re-check it
- Crawl the site and confirm no canonical chains or loops exist
