Google Must Reveal How Publisher Content Performs in AI Search Versus Web Results

The UK's Competition and Markets Authority has required Google to disclose disaggregated performance data to publishers—separating metrics for AI Overviews from traditional search results. Publishers currently cannot measure whether their content appears in AI features at all, preventing rational decisions on indexing and licensing. The requirement, imposed as part of broader conduct obligations on 17 June 2026, addresses a structural gap as AI increasingly replaces the answer-layer in search.
