Do I need to do anything special to appear in an AI overview?

Google says no. Its documentation states there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary. The one hard requirement is eligibility: a page must be indexed and eligible to be shown in Google Search with a snippet.

How do I stop my content appearing in an AI overview?

Use the snippet controls. Google documents nosnippet, data-nosnippet, max-snippet and noindex as the way to limit what is shown from your pages, and states that the max-snippet limit applies to AI features too. There is no separate AI-only opt-out that keeps ordinary snippets intact.

Is an AI overview the same thing as AI Mode?

No. An AI overview is a summary placed above the ordinary results for a normal search. AI Mode is a separate conversational surface that Google describes as particularly helpful for queries needing further exploration, reasoning or complex comparisons. The eligibility rules are shared; the surfaces are not.

Does appearing in an AI overview send traffic?

Less than a blue link does. In the same Pew study, users who encountered an AI summary clicked a traditional search result in 8% of visits against 15% for visits without one, and clicked a link inside the summary itself in 1% of visits.

Q: How often does a Google search produce an AI overview?

In a Pew Research Center study of 68,879 Google searches made by 900 US adults during March 2025, 18% of searches generated an AI summary. That is a measurement of one panel in one month in one country, not a fixed rate.

An AI overview is the AI-generated summary Google places above the ordinary results for a search. Google describes them as helping people get to the gist of a complicated topic or question more quickly, and providing a jumping off point to explore links to learn more. The summary is composed by a model from material Google has already indexed, and it carries supporting links to the pages it drew on.

How common they are, and what they cost in clicks

The best public measurement comes from a Pew Research Center analysis of 68,879 Google searches made by 900 US adults who shared their browsing data during March 2025. In that dataset, 18% of searches generated an AI summary. Users who encountered one clicked a traditional search result in 8% of visits; those who did not encounter one clicked a result in 15% of visits, nearly twice as often. Clicks on the links inside the summary itself happened in 1% of visits.

Read those figures carefully. They describe one panel, in one country, in one month, on one search engine. They are the right order-of-magnitude anchor for a business case and the wrong thing to quote as a permanent constant.

Eligibility is the whole mechanism

Google's documentation on AI features is unusually direct about how a page qualifies. It states that there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary, and that to be eligible to be shown as a supporting link a page must be indexed and eligible to be shown in Google Search with a snippet, fulfilling the Search technical requirements.

Two consequences follow, and both are usually missed.

First, there is no AI-specific markup, schema type or file that opts a page in. Eligibility is inherited from ordinary indexing.

Second, the opt-out is shared with ordinary snippets. Google names nosnippet, data-nosnippet, max-snippet and noindex as the controls that limit what is shown from your pages, and its robots meta documentation states that the max-snippet limit applies to AI features as well. A publisher who wants out of AI overviews but keeps ordinary snippets has no supported way to have both. noindex vs nosnippet works through what each rule actually removes.

There is a third consequence that catches sites out. A serving rule only works if the crawler can read it: if a page is disallowed in robots.txt, Google's documentation states that any information about indexing or serving rules will not be found and will therefore be ignored. Blocking the crawler is not a way to suppress a snippet.

How it differs from a featured snippet

A featured snippet is an extract. Google's systems select an existing passage from one page and reverse the usual result layout to show the description first, and clicking through scrolls the reader to that passage on your page. An AI overview is a composition: a model writes new prose that synthesises several sources, and the sources appear as supporting links rather than as the body of the answer.

The practical difference is attribution. A featured snippet is unambiguously your text, credited to your URL. An AI overview may reproduce the substance of your page in sentences that are not yours, with your link one of several beneath. That is why source citation is worth tracking as its own thing rather than as a proxy for traffic.

How to act on it

Confirm the page is indexed and snippet-eligible before anything else. Nothing downstream matters if it is not.
Audit your max-snippet values. A conservative limit set years ago for a different reason now also restricts AI features.
Decide the opt-out question deliberately rather than by inheritance, and record the decision, because the two outcomes are coupled.
Track appearances by sampling a fixed set of prompts and queries, not by watching sessions, since zero-click search means the traffic signal understates the exposure.
