How Google AI Overviews and AI Mode Pick Local Businesses

Ask Google about a service in your town and an AI-written answer naming a few businesses often appears first. If yours isn't among them, you want to know how Google AI Overviews pick a local business and how to get in.

The short version: Google Search Help describes AI Overviews as an AI-generated snapshot shown when its systems decide generative AI can be especially helpful, and AI Mode as its most powerful AI search, which splits a question into subtopics, searches each at once and answers with links to the web. Google's Search Central documentation says a page needs nothing extra to appear in either: it must be indexed and eligible to show in Google Search with a snippet, with no additional requirements and no special markup. Google's guide to generative AI features adds that AI responses can include information about local businesses, and that an up-to-date Business Profile can help you be visible in them.

That is most of what Google has put in writing. This post covers Google only; our comparison of how ChatGPT, Perplexity and Google AI pick a local business covers the other engines and our own scan counts.

How Google says AI Overviews and AI Mode choose what to show

Google's Search Central documentation says both features may use what it calls query fan-out: issuing multiple related searches across subtopics and data sources. One question about an emergency plumber becomes several searches behind the scenes, and your page has to be a good result for at least one of them.

Google's guide to generative AI features says these features are rooted in its core Search ranking and quality systems, which retrieve relevant, up-to-date pages from the index, and that the answer shows clickable links to the pages that support it. The AI features page says a supporting link must be an indexed page that is eligible to show in Search with a snippet, and it warns that "Indexing and serving isn't guaranteed."

For the map list, Google's Business Profile help says local results are mainly based on relevance, distance and prominence (which includes how many websites link to a business and how many reviews it has), and that "There's no way to request or pay for a better local ranking on Google." That page never mentions AI Overviews or AI Mode, so whether the same factors pick the businesses inside an AI answer is something Google has not published.

Google Search Help says AI Mode can research service costs, find open appointment slots and check stock nearby, by reading the web, filling in forms or calling businesses directly; a July 2025 post on Google's blog says businesses control those calls through their Business Profile settings. Google's Business Profile help adds that profile information, including what it crawls from your own website, is used to surface local results in Maps and Search; our post on Google Business Profile as an AI input covers which fields to fill in.

What Google says you can and cannot control

Google's AI features page lists a few controls, all of which apply to Search as a whole.

Crawling. Google's Search Central documentation says robots.txt directives for Googlebot are the control for Search, and its crawler documentation says Googlebot settings affect every Google Search feature. Block Googlebot and you leave regular results too; Google lists no switch for AI Overviews alone.
Snippets. The same page says to limit what is shown from your pages with nosnippet, data-nosnippet, max-snippet or noindex; Google's snippet documentation explains that nosnippet blocks any snippet, max-snippet caps its length and data-nosnippet excludes a marked part of the page. Since eligibility needs a snippet, our reading is that nosnippet also keeps a page out of the supporting links.
Timing. Google's AI features page says a preview control must be visible to Googlebot, and that recrawling can take anywhere from several days to several months.
Google-Extended. Google's crawler documentation describes it as a token that controls whether crawled content may be used to train future Gemini models and for grounding, and states that it does not affect inclusion in Google Search and is not a ranking signal. Google Search Help calls AI Overviews a core Google Search feature, so blocking Google-Extended is not a way out of them, and allowing it is not a way in.
Phone calls. Google's Business Profile help names the setting Google automated calls and text messages, under Business Profile settings and then Advanced settings.

Google's pages list no control that lets a business opt out of being named or described in an AI answer.

A checklist for a local business

Items one to six are Google's documented recommendations; the last three are ours.

Crawling allowed in robots.txt and by your CDN or host (Google).
Every important page reachable through internal links (Google).
Important content available as text, not only inside images or video (Google).
A great page experience (Google): fast, stable and readable on a phone.
Structured data that matches the visible text, with no expectation that it is required (Google).
A verified Business Profile with complete, accurate information and hours, reviews answered and photos added (Google's local ranking help).
One page per service that answers the buyer's question in plain text in its first paragraph, with the service and the area in the heading (ours).
The same name, address, phone number and hours on your site, your profile and every directory (ours).
LocalBusiness and FAQ structured data that repeats what the page already says; our schema markup guide shows the minimum (ours).

Google's generative AI guide also says you don't need llms.txt or other special files, which Google Search itself doesn't use, or content rewritten just for AI systems.

How to check whether you appear in Google AI Overviews and AI Mode

Start with the searches your buyers type. Run eight or ten of them in AI Mode and in ordinary Search, and write down which businesses are named and which pages are linked as sources. Repeat on a schedule, because an AI Overview appears only when Google's systems decide it is helpful, and the answer can change between runs.

Then open Search Console. Google's AI features page says sites appearing in AI Overviews and AI Mode are included in overall search traffic, reported in the Performance report under the Web search type. Search Console Help also describes a Generative AI performance report for Search covering both features, where an impression is how many times links to your site were shown in a generative AI feature, and Google's Search Central blog says it breaks those down by page, country, device and date. The help page notes the report usually doesn't appear until a site has enough impressions, so a missing report is itself a result.

What Google has not published

Google does not publish how it chooses the businesses inside an AI answer, how many to name, or how it weighs reviews, distance and your website. Its local ranking page says the algorithm details are kept confidential, and its AI pages describe eligibility, not selection. Anyone selling a ranked list of AI Overview ranking factors is guessing.

Results also vary by person: a May 2025 post on Google's blog says AI Mode can use personal context, such as restaurants with outdoor seating based on past bookings. And our own numbers, from the free check at /aeo, come from Gemini with Google Search grounding through the API, not from AI Overviews themselves, so treat any single screenshot, including ours, as one sample.

Google has written down the entry requirements and none of the selection rules, so the work is making every page and the profile eligible, then measuring.

Frequently asked questions

Do I need special markup or an llms.txt file to appear in Google AI Overviews?

No. Google's Search Central documentation says there are no additional requirements to appear in AI Overviews or AI Mode and no special optimizations; a page must be indexed and eligible to show in Google Search with a snippet. Google's generative AI guide adds that Google Search does not use llms.txt files and that structured data is not required, though structured data still helps a page qualify for rich results in ordinary search.

Does blocking Google-Extended remove my business from AI Overviews?

No. Google's crawler documentation says Google-Extended controls whether crawled content may be used to train Gemini models and for grounding, and that it does not affect a site's inclusion in Google Search or act as a ranking signal. AI Overviews and AI Mode are Google Search features crawled by Googlebot, so the robots.txt rules for Googlebot and the nosnippet, max-snippet and noindex controls are the ones that matter for them.

Can I see AI Overviews traffic in Google Search Console?

Yes, in two places. Google's AI features documentation says traffic from sites shown in AI Overviews and AI Mode is included in the Performance report under the Web search type. Search Console Help also describes a Generative AI performance report for Search that shows impressions, meaning how many times links to your site appeared in AI Overviews or AI Mode, broken down by page, country, device and date. The report only appears once your site has enough of those impressions.
