1.3 CanonicalisationMediumInferred
Canonicalised page still in sitemap
Listing a non-canonical URL in the sitemap tells Google to treat it as a priority page while the canonical tells it not to. The sitemap should only contain canonical, indexable URLs.
What it is
A non-canonical URL is listed in the sitemap.
Why it matters
Mixed signals: sitemap implies ‘index me’ while canonical points elsewhere.
How to fix it
List only canonical URLs in sitemaps.
How to find it on your site
- Cross-reference your sitemap URLs against the canonical of each.
- Flag sitemap entries whose canonical points elsewhere.
- Remove the non-canonical URLs from the sitemap.
- Keep the sitemap limited to canonical, 200, indexable pages.
Cross-reference to ranking and citation factors
Mixed signals between sitemap and canonical waste crawl attention. A clean sitemap reinforces the canonical choice.
Impact
Low-medium. Inferred.
Evidence
Sitemaps should contain canonical URLs. Google Search Central, Build and submit a sitemap; Google Search Central, Consolidate duplicate URLs (canonicalization)
