How AI Overviews choose sources
AI Overviews are generated from Google's search index, so pages need to be indexed and eligible for search to appear. Google says no special markup is required; helpful, clear content and normal SEO best practices apply. The cited pages are not always the top ranking results.
What it means for brands
- Track AI Overviews separately from organic rankings; you can rank and still be left out, or be cited without ranking first.
