How the Google AI Overviews Algorithm Works in 2026
Last reviewed .
Every claim links to its official source. By Muhammed Abdul Kalam
Google AI Overviews appear automatically when Google's systems determine that generative AI can be especially helpful for a query — typically when synthesising information from multiple sources. They cannot be turned off by users, though the Web filter provides a way to get text-only results. Google officially acknowledges that AI responses may include mistakes.
Google AI Overviews (previously called Search Generative Experience) are AI-generated summaries that appear at the top of some Search results pages. They are produced by generative AI and include links to supporting sources. The claims below come directly from Google's official Search Help Centre documentation.

Google AI Overviews appear when Google's systems determine that generative AI can be especially helpful — particularly when synthesising information from multiple sources.
Google describes AI Overviews as powered by generative AI — a type of artificial intelligence that learns patterns and structures from the data it is trained on.
Google officially acknowledges that AI Overviews may include mistakes, can produce inaccurate or offensive information, and that users should verify important information elsewhere.
Google uses interactions with AI Overviews — including search queries and user feedback — to develop and improve its generative AI, with identifying information removed by automated tools.
When does Google show an AI Overview for a search query?
Google states AI Overviews appear "when our systems determine that generative AI can be especially helpful" — particularly when the user wants to understand information from multiple sources quickly.
Are Google AI Overviews always accurate?
No. Google's own documentation states: "AI responses may include mistakes" and that the system "can and will make mistakes" and "may provide inaccurate or offensive information." Google recommends users verify important information elsewhere.
Can you turn off Google AI Overviews?
No. Google's Help Centre explicitly states: "Features cannot be turned off." However, users can select the Web filter after searching to see only text-based links without AI Overviews.
Does Google use your AI Overview interactions to train its models?
Yes. Google states it uses "interactions with Search and these AI experiences" including search queries and user feedback "to develop and improve generative AI." Personal identifiers are removed by automated tools before use.
Do AI Overviews link to sources?
Yes. Google describes AI Overviews as providing "an AI-generated snapshot with key information and links to dig deeper" — source links are included alongside the generated summary.
