Google AI Overviews

Also called: AI Overviews, Google Search AI, SGE (legacy name)

Common prompts: "what is Google AI Overviews," "what is the AI summary in Google search," "AI Overviews vs Gemini"

Definition

Google AI Overviews is the generative answer feature inside Google Search results, rolled out broadly in 2024. It produces a composed answer at the top of the results page for many consumer and informational queries — sitting above the traditional ten blue links and drawing from a finite set of retrieved sources.

Why it matters

Google AI Overviews is the largest-traffic answer engine in the world because it inherits Google Search's user base. For categories where consumers still start at Google, the Overviews box is the new front door. Brands that ranked on page one of Google but do not appear in the Overviews answer have lost the click — the buyer reads the summary and moves on. Citation Share on Overviews is the critical bridge metric between SEO and AI Communications.

Example

A pet food brand at #1 on Google for "best dog food for sensitive stomachs" discovers Google AI Overviews names three other brands first in the composed summary. Click-through to the brand's #1-ranked page drops 38% in the months after Overviews rollout. The SEO position is intact. The answer-layer position is not.
