Index Coverage.
Learn what Index Coverage means in modern search and SEO.
The Google Search Console report showing which pages on a site are indexed by Google and which are excluded—with reasons for exclusion.
The Index Coverage report in Google Search Console categorises every URL Google has encountered on a site into four statuses: Valid (indexed), Valid with Warning (indexed but with potential issues), Excluded (not indexed, for various reasons), and Error (Google tried to index but encountered a problem preventing indexing).
Common Exclusion Reasons
Key exclusion reasons include: Crawled—currently not indexed (Google discovered but chose not to index), Noindex (the page carries a noindex directive), Canonical—alternate selected (Google chose a different URL as the canonical), Page with redirect (the URL redirects to another), and Not found (404 error). Each reason requires a different investigation and remediation approach.
Using Index Coverage for Auditing
Comparing the total indexed URL count against the expected number of indexable pages reveals over-indexing (tag pages, faceted navigation variants, or parameters consuming crawl budget) or under-indexing (important pages inadvertently excluded by misconfigured robots.txt, noindex tags, or canonicals). Index Coverage is the starting point for any technical SEO audit.
