No recursive canonical
What the check finds
The canonical chain loops back on itself, so no target can be resolved.
Why it matters for AI answers
When canonicals point at each other in a loop, there is no clear version to index. Search engines then choose on their own, or index neither page well.
How to fix it
- Pick one URL as the preferred version for this content.
- Point rel="canonical" on every duplicate at that URL.
- Give the preferred URL a self-referencing canonical.
