Google AI Overviews now cite an average of 2.4 sources, down from 4.1
A July 2026 audit of 1,000 AI Overview queries shows Google is collapsing citations to fewer, higher-authority domains.
Google's AI Overviews have quietly reduced the number of cited sources per answer from 4.1 (Jan 2026) to 2.4 (July 2026). The cut disproportionately hit mid-tier publishers; sites with strong Organization + Person schema and a documented author entity graph retained citation share.
The change reinforces a pattern we flagged in our own AI Citation Benchmark: entity clarity — a real, sameAs-linked author with a persistent URL — now outweighs raw domain authority for AI Overview inclusion.
Prioritise author pages with sameAs links to LinkedIn, X, and Wikipedia over chasing more backlinks. AI Overviews reward disambiguated entities.
