The Page indexing report shows URLs under "Duplicate, Google chose different canonical than user" or "Duplicate without user-selected canonical", meaning Google's deduplication picked a URL other than the one the site intends. Google documents that canonicalisation, often called deduplication, shows only one version of duplicate content. When Google overrides the declared canonical, the site's preferred URL is not the one shown and signals may consolidate elsewhere.
Why does search console reports google choosing a different canonical than declared matter for AI search?
Google documents that canonicalisation, often called deduplication, shows only one version of duplicate content. When Google overrides the declared canonical, the site's preferred URL is not the one shown and signals may consolidate elsewhere.
How do you fix it?
Make canonical signals agree: redirects, rel=canonical, internal links and sitemap entries should all point to the same URL. Where pages are not true duplicates, make their content substantially different.
How do you find it on your site?
- Open Search Console, Indexing, Pages, and list the "Duplicate" statuses with their example URLs.
- Run URL Inspection on a sample to compare the user declared canonical with the Google selected canonical.
- Crawl the site to check that redirects, rel=canonical, internal links and sitemap entries point to the same URL for each cluster.
- Record clusters where Google's choice differs from the intended URL and prioritise by traffic.
