How AI Overviews works: queries fan out to live web index, then synthesize sourced answers
lilyraynyc · x · 2026-09-16
SEO practitioner Lily Ray explains the mechanics of Google AI Overviews / AI Mode: a single query is turned into multiple fan-out queries run against the live web index, and relevant passages are synthesized into an answer with sources attached.
Her argument for why this goes beyond 10 blue links: users are asking longer, more detailed questions that need nuance and context, and AIO helps them find what they are actually looking for.
