Canonical URL mismatch
The canonical tag points to a different URL than the page you're on. AI systems may consolidate signals to the wrong URL.
Common causes
- Canonical points to www while page is non-www (or vice versa).
- Trailing slash mismatch.
- HTTP vs HTTPS mismatch.
Fixes
- Ensure canonical matches the preferred URL exactly.
- Use a consistent URL format across the site.
- Validate with a canonical checker.
