Check 13 / 19 LOW impact In the full checklist
Fix duplicate /collections/all vs /collections
What this check is
A catalogue reachable at two URLs, with and without a path segment, splits the signals and can produce two similar results in search. One canonical view is the fix, with the other redirected.
How to implement it
Decide which of the catalogue URLs is canonical, add a server-side redirect from the other variant to it, and make sure internal links and the sitemap use only the canonical form. Check for other duplicates at the same time: paginated, sorted and filtered variants.
How to verify it
Request the non-canonical URL and confirm it redirects in a single hop to the canonical one, and that the canonical URL is the one listed in the sitemap.
