What are Google AI Overviews?
What do AI Overviews do?
A person types a question. On the results page, Google may show a written summary with links to pages it drew on. The searcher may get what they need without opening any of them.
"AI Overviews" is the name of a Google product. "AI Mode" is a related feature and a separate name. Google describes AI Mode as particularly helpful for queries that need further exploration, reasoning or complex comparisons1. Do not use the two as synonyms.
Do AI Overviews cost clicks?
Probably, for some searches. Pew Research Center looked at a panel of US adults in March 2025. Those who saw an AI summary were less likely to click on links to other websites than those who did not2. That is one US panel, one month of Google searches. It does not describe Europe, and it does not describe your category.
So treat "fewer clicks" as a reason to measure, not as a fact about your shop.
What do you need to do to appear?
Less than the pitch decks suggest. Google's own guidance says a page needs to be indexed and eligible for a snippet, with no special schema or extra technical requirements1. Its guide on generative AI search adds that files such as llms.txt are ignored by Google Search, and that no third-party tool has access to its internal ranking or AI systems3. So a promise of placement is a promise nobody can keep.
To see where you stand, Google says traffic from AI features is included in the Search Console Performance report1.
For ZFD: We would measure it before we sell it. What Search Console can show is covered in Search Console AI Overviews report. How the labels fit together is in AEO vs GEO vs SEO.

FAQ

Do I need special markup to appear in AI Overviews?
No. Google says no special schema or extra technical requirements apply beyond being indexed and snippet-eligible1.
Will AI Overviews cut my traffic?
It may, for some searches. A US panel study found fewer link clicks when a summary appeared2. Check your own Search Console data before you act on it.
Is it the same as AI Mode?
