How to track brand visibility in Google AI Overviews
Google AI Overviews is the AI summary Google places above the classic results on informational queries. Nostimates tracks it by rendering the real SERP with your target country and language, then parsing the 3–5 citation chips and the brands named in the summary text, sampled n times per prompt.
What matters on this engine
AI Overviews appear on roughly 47% of general informational searches and up to 84% of health queries, per BrightEdge. They rolled out broadly in the US in May 2024 and now run in 200+ countries and 40+ languages.
At I/O in May 2026 Google put the surface at 2.5 billion monthly users — Google's own figure, not independently verified — which would make it an order of magnitude larger than ChatGPT and the single most important surface any visibility product parses.
Collection is fully anonymous: it is a SERP request with gl and hl set. No account, no login. This is the cheapest surface we cover and the one with the most people behind it.
