Definition: what is AI Mode?
AI Mode is a standalone mode of Google Search (introduced in the US in 2025, expanded step by step since), in which Gemini-based models answer queries conversationally. Instead of a SERP with an optional AI summary, a dialogue emerges: users ask follow-ups, refine and compare — search becomes a session. Sources appear as citations inside and next to the generated answer.
AI Mode vs. AI Overviews: the engine difference
- Surface: AI Overviews appear above classic results; AI Mode is its own, fully generative surface.
- Interaction: Overviews answer a single query; AI Mode runs multi-turn dialogues with session context.
- Fan-out depth: AI Mode decomposes queries more aggressively into sub-queries (query fan-out) and synthesises from more retrieval runs.
- Citation logic: citation selection and display differ — the same domain can be cited in Overviews and absent in AI Mode, and vice versa.
Optimisation consequences
Three shifts shape the work for AI Mode:
- Passage engineering for reasoning chains: answers are built from argument skeletons across several sources; passages must work as individual argument building blocks — precise, dated, standalone.
- Multi-turn coverage: sessions move from overview to detail and comparison questions. Content clusters must cover the follow-up spaces, not just the entry question (topical map).
- Entity consolidation: over long sessions, brand attribution drifts when entity signals are inconsistent — consistent attributes across all sources are the safeguard.
Measurement
Since June 2026 (launched June 3, available to all sites since August 31, 2026), the GSC generative AI report officially reports impressions from AI Mode — without clicks and without queries. For citation and competitive views, prompt-based tracking remains necessary: citation rate and share of model collected separately per surface.

AI Mode is its own engine, not an Overviews offshoot
Own tab, multi-turn, deeper fan-out, own citation logic: AI Mode needs its own optimisation and measurement strategy — Overview tactics do not transfer automatically.
FAQ on Google AI Mode
What is the difference between AI Mode and AI Overviews? ▾
AI Overviews are generative summaries above the classic results of a single query. AI Mode is a standalone conversational surface with multi-turn dialogue, deeper query fan-out and its own citation logic. Visibility in one surface guarantees nothing in the other.
How do you optimise for AI Mode? ▾
Through three levers: passages that work as standalone argument building blocks in reasoning chains; content clusters that also cover the session's follow-up and comparison questions; and consistent entity signals against brand drift across long dialogues.
Can AI Mode visibility be measured? ▾
Partly officially: since June 2026 the GSC generative AI report shows impressions from AI Overviews, AI Mode and generative Discover features — without clicks and queries. Citation and competitive data only come from prompt-based tracking per surface.
Is AI Mode available in Europe? ▾
Yes, in many markets. After the US launch in 2025, Google expanded AI Mode on October 7, 2025 to more than 35 additional languages and over 40 additional countries and territories, many of them in Europe; it is now available in over 200 countries and territories. Individual features still vary by market and language.
