Resolve conflicting canonical signals across self-referencing, cross-domain, and noindex cases

Steps

  1. Inventory all canonical signals for a URL set: rel=canonical tag, HTTP Link header, sitemap inclusion, internal links, and any redirect chain
  2. Flag pages where the rel=canonical target conflicts with a noindex directive on the same page — Google treats this as a conflicting signal and may pick either
  3. Flag cross-domain canonicals pointing to a URL that itself 404s, redirects, or is blocked by robots.txt, since an unreachable canonical target gets ignored
  4. Verify every canonicalized page returns 200 directly (not through a redirect) and is self-consistent if it's meant to be its own canonical
  5. Use URL Inspection's "Google-selected canonical" field to confirm Google's actual choice matches your declared canonical, and investigate mismatches
