Google AI Mode
In one line
Google AI Mode is a Gemini-powered search mode inside Google Search that runs like a dedicated tab — a full-screen, conversational extension of AI Overviews.
Going deeper
Google AI Mode is the Gemini-powered search mode Google announced in 2025. It goes a step beyond placing an AI Overview on top of regular results — selecting AI Mode reshapes the entire screen around an AI answer with follow-up prompts. Functionally it is closer to a full-screen, conversational version of AI Overviews.
What stands out for marketers is how aggressively query fan-out runs on this surface. A single prompt expands into multiple sub-queries and naturally rolls into follow-ups, so pages that cover the cluster of sub-questions tend to be cited more than pages built around a single keyword.
AI Mode appears to share the Gemini model line with AI Overviews, but reports suggest the answers and cited sources are not always identical. Public detail is thin, so a fair amount is inferred — for GEO monitoring it is safer to track AI Mode as a separate surface alongside AI Overviews.
