AI search for local businesses, Google AI Mode, AI Overviews and ChatGPT

What is AI search for a local business?

AI search is an AI tool answering a question in its own words, with links to sources. A local business meets three kinds of it, which are Google AI Mode, AI Overviews and ChatGPT with Perplexity. For a local business, it means a customer asks an AI tool who to call, and the answer can name a business, so the facts held about yours matter.

The table below shows what each AI search surface is and where it shows, so you know which ones your customers can meet.

What is Google AI Mode?

Google AI Mode is Google's most powerful AI search experience, according to Google Search Help. Google says AI Mode is particularly helpful for queries where further exploration, reasoning or complex comparisons are needed. It splits a question into subtopics, searches each one at the same time and links to sources, and it may show web links instead when it is not confident in an AI response.

For local searches, Google's Search Help page on checking local availability and pricing says AI Mode gathers information from across the web, and that when businesses have limited information available online, Google can make calls for the person searching. That is one more reason to keep your details complete and current.

How does query fan-out work in AI Mode?

Query fan-out is Google issuing multiple related searches across subtopics and data sources, and both AI Overviews and AI Mode may use it, according to Google Search Central. One customer question becomes several searches behind the scenes. For example, a question like "who fixes a water heater near me tonight" can fan out into three searches.

1. Plumbers who repair water heaters
2. Plumbers open after hours
3. Reviews of Springfield plumbers

That example is an illustration, not a record of what Google ran. It shows why more than one page on your site can answer one customer question, so a clear page for each service you sell gives AI Mode more to work with.

What are Google AI Overviews?

Google AI Overviews give a fast summary of a complicated topic with links to read more, and Google shows them only when its systems determine they are additive to classic Search. In a 2025 Whitespark study of 540 searches in three US cities, an AI Overview appeared on 15% of local-intent searches and on 92% of informational searches. A local pack appeared on 93% of the local-intent searches and on 6% of the informational ones.

The table shows how often each result appeared by kind of search, in Whitespark's 2025 study of 540 searches in Houston, Phoenix and Denver.

One reading of these numbers is that a plain trade search like plumber near me still ends mostly in the map pack, while a how-to question mostly gets an AI Overview.

How are AI Overviews different from AI Mode?

AI Overviews give a quick summary, while AI Mode handles questions that need deeper reasoning. The table sets the two side by side.

The table shows what each Google surface is, what it is built for and how it searches, so you can tell which one a customer is looking at.

Traffic from both is included in your overall search traffic in Search Console.

How do ChatGPT and Perplexity find local businesses?

ChatGPT and Perplexity find local businesses by searching the web and pulling from sources, which makes them part of AI search for your customers, and in a 2024 BrightLocal study of ChatGPT Search, 58% of local sources were business websites. Perplexity says it interprets your question, searches the internet in real time, gathers material from sources and condenses it into a conversational answer with numbered citations. BrightLocal's study, "Uncovering ChatGPT Search Sources", split the local sources three ways.

• Business websites, at 58%
• Business mentions on other sites, at 27%
• Directories, at 15%

SOCi's 2026 Local Visibility Index found that recommended businesses averaged 4.3 stars on ChatGPT, 4.1 on Perplexity and 3.9 on Gemini.

How do you rank in ChatGPT as a local business?

Nobody controls how you rank in ChatGPT, and the three source types in BrightLocal's study point to three jobs.

• Keep your website clear about what you do and where you do it.
• Earn mentions of your business on other local sites.
• Match your details across your directory listings.

OpenAI's bots documentation says OAI-SearchBot is used to surface websites in ChatGPT's search features, and OpenAI recommends allowing it in robots.txt. Sites that opt out are excluded from ChatGPT search answers, though they can still appear as navigational links, and changes can take about 24 hours to take effect.

Where do AI answers get facts about your business?

ChatGPT Search drew its local sources from these three places in BrightLocal's 2024 study, so those are the three places to keep your business facts right.

• Your website
• Mentions of your business on other sites
• Directory listings with your business details

For Google's AI features, a page is cited only when it is indexed and eligible to show in Search with a snippet. Your Google Business Profile is the business record Google asks owners to keep complete and accurate, and Google says businesses with complete and accurate info are more likely to show up in local search results. Google's AI features page lists keeping Business Profile info up to date among general SEO fundamentals and does not say it feeds AI Overviews or AI Mode.

Why do matching business details matter for AI search?

Matching business details matter because only 68% of business contact information on ChatGPT and Perplexity matched Google Business Profile details, according to SOCi's 2026 Local Visibility Index. A mismatch means your name, phone, address or hours differ from one place to the next.

Fix your Business Profile first, because it is the record Google asks you to keep right. Google says your name should reflect your business's real-world name, your address should be precise and accurate, and you should provide regular customer-facing hours. Then make every other listing say the same name, phone, address and hours.

How can a local business show up in AI answers?

A local business shows up in Google's AI answers by following the same basics that get a page into Google Search, because Google says there are no additional requirements and no other special optimizations necessary. Five steps cover those basics.

1. Keep your pages indexed and able to show in Google Search with a snippet.
2. Keep your Google Business Profile complete and accurate.
3. Write pages that answer your customers' questions in plain words.
4. Keep your name, phone, address and hours the same everywhere.
5. Skip the special files and extra markup, because Google says they are not needed.

Google adds that there is no special schema.org structured data you need to add, and structured data should still match the visible text. We cannot promise a citation, and nobody can. If you want help checking and fixing these five things, we offer AI search visibility for local businesses, so AI answers can find and name you.

Does llms.txt help a business appear in AI search?

No, llms.txt is not needed to appear in Google's AI Overviews or AI Mode. Google says "You don't need to create new machine readable files, AI text files, or markup to appear in these features." This answer covers Google's AI features only, and it means you can skip any offer that sells you an llms.txt file as a way into Google's AI answers.

How do you check what AI search says about your business?

You check what AI search says about your business by asking the AI tools your customers' questions and reading the answers against your own facts. Three steps make the check.

1. Ask ChatGPT, Perplexity and Google AI Mode the questions a customer would ask about your trade and town.
2. Open the Performance report in Search Console and filter to the Web search type, where traffic from Google's AI features is counted.
3. Compare the name, phone, address and hours the tools give with your Google Business Profile.

Search Console is a free Google service that shows how often a site appears in Search, which queries surface it and how often people click through. As one example, a Springfield client went from 39 to 65 Google AI Overview appearances in Semrush, Sep 16 to Oct 16, 2026 against the previous 28 days. That is one business over one period, and it is not a promise for yours.

How is AI search different from SEO, AEO and GEO?

AI search is a kind of search experience, while SEO, answer engine optimization (AEO) and generative engine optimization (GEO) are labels for the work that helps a business show up in it. Four labels cover most of what you will hear, and they are market labels, not Google terms.

• AI search, the Google and third-party tools that answer in their own words.
• SEO, the work that helps your pages show in Google Search.
• Answer engine optimization (AEO), the work of making content easy for answer engines to find, understand and quote.
• Generative engine optimization (GEO), the work of helping a business be found, understood and cited in AI answers.

Google says no special optimization is needed to appear in its AI features.
