How a local business gets mentioned by ChatGPT and Google's AI answers

The short answer on AI visibility

A local business gets mentioned in AI answers mostly the same way it gets found in search: its website can be crawled, says clearly what it does and where, and is backed up by other sites that mention it. Google says there is no special file, markup or trick needed for its AI features, and the AI companies publish which crawlers they use, so the first job is simply not to block them.

There is a lot of confident advice about "AI optimization" online. Much of it is guesswork. This guide sticks to what Google, OpenAI, Anthropic and Perplexity have published themselves, adds one public study on local results, and is clear about what nobody has proven yet. Every claim links to its source, with the date we read it.

How Google's AI Overviews and AI Mode pick sources

Google's documentation on AI features says: "There are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." To be eligible, a page has to be indexed and eligible to appear in Google Search with a snippet, which are the normal Search requirements (Google Search Central, AI features and your website, last updated 10 December 2025, read 27 October 2026).

The same page explains that these features may run several related searches across subtopics to build an answer, which lets them show a wider set of links than a normal results page. In practice, that means a page that answers the follow-up questions a customer would ask (cost, timing, area served, license) has more chances to be one of the sources.

Google's separate guide to its generative AI features goes further. It says "You don't need to create new machine readable files, AI text files, markup, or Markdown to appear in Google Search", that "Google Search itself doesn't use them", that "There's no requirement to break your content into tiny pieces", and that "Structured data isn't required for generative AI search" (Google's guide to optimizing for generative AI features, last updated 10 July 2026). Its main advice is to keep doing sound SEO and to publish original, expert material.

Google also reports AI-feature traffic inside Search Console's Performance report, under the "Web" search type, so you can see some of the effect without paying for a tool (same AI features page as above).

How ChatGPT, Claude and Perplexity find websites

The other assistants each run their own crawlers and publish their names. If your site blocks them, through your robots.txt file or a firewall setting at your host, they can't read you.

OpenAI's page says that to appear in ChatGPT search results you should allow OAI-SearchBot in robots.txt, and that changes can take about 24 hours to be picked up. Blocking the training crawler (GPTBot) is a separate choice from blocking the search crawler; you can allow one and not the other.

A common accident: some hosting and security settings block "AI bots" with one switch. That can remove you from AI search answers without you knowing. Check your host's bot settings and your robots.txt file (it lives at yourdomain.com/robots.txt).

What one study found about local AI answers

BrightLocal, a local SEO software company, ran 800 local business searches in ChatGPT in November 2024 across 20 business types and 20 U.S. cities, and recorded the sources it cited. Business websites were 58% of the sources, mentions of the business on other sites were 27%, and directories were 15% (BrightLocal, Uncovering ChatGPT search sources, published 12 December 2024, updated 14 November 2025).

Two cautions. The data is from late 2024, and ChatGPT's search has changed since. And it is one study by a vendor in this market. Still, it points the same way as Google's guidance: your own website is the source an assistant leans on most, so it should state your services, area and contact details plainly, in text.

Write pages that answer the follow-up questions

Because Google's AI features break one question into several related searches, the pages that get used tend to be the ones that answer the obvious next questions in plain text. A customer who asks "who can replace my roof in [my town]?" also wants to know cost, timing, licensing and what happens if it rains mid-job. If your page answers those, an assistant has something specific to quote. If it only says "quality roofing, call today", it doesn't.

Here is an example of the questions a single service page could answer, using a roofing company. Swap in your own trade.

Start each section with a direct one- or two-sentence answer, then the detail. That helps a busy reader as much as it helps a machine.

What is still unproven

Here is where we draw the line between what is documented and what is a reasonable bet.

• llms.txt. This is a proposal, first published by Jeremy Howard in September 2024, for a plain-text file that helps AI agents use a website (llmstxt.org). Google says Google Search doesn't use such files. Some AI tools and agents may read it. It is cheap to add; nobody can show it gets a business mentioned more.
• Schema markup for AI. Google says no special markup is needed for its AI features. Structured data still helps search engines understand your business details, and costs little, but it is not an AI switch.
• "Ranking" in ChatGPT. Answers change between sessions, between users and over time. Anyone selling a guaranteed position in an AI answer is selling something no one controls.
• Third-party "AI visibility scores". Tools that track AI mentions sample a set of questions. They are useful for spotting trends, not as exact measurements.
• Brand mentions on other sites. It is widely believed that being mentioned on trusted sites helps, and the BrightLocal data is consistent with that, but no AI company has published how much weight mentions carry.

An AI visibility checklist for a local business

None of these items needs special software. Most take under an hour.

1. Check your robots.txt and host bot settings. Make sure Googlebot, OAI-SearchBot, Claude-SearchBot and PerplexityBot are not blocked, unless you have chosen to block them.
2. Make sure Google has indexed your key pages. Search site:yourdomain.com, or use Google Search Console.
3. Put the basics in text on your site: business name, what you do, the towns you serve, phone, hours, license number. Not only in images or a PDF.
4. Answer the real questions on the page. Cost ranges, how long a job takes, what's included, warranty. These are the follow-up questions AI features search for.
5. Keep one version of the facts. The same name, phone and area on your site, Google Business Profile, Bing Places, Apple Business Connect and directories.
6. Complete your Google Business Profile. It is the core of local search on Google. See our Business Profile guide.
7. Earn real mentions. Supplier and manufacturer directories, local associations, local news, sponsorships. Real, not bought.
8. Collect honest reviews on the platforms customers use, and answer them.
9. Add structured data for your business and test it with the Rich Results Test. Helpful for search; not required for AI features.
10. Optionally add llms.txt with your plain facts. Low cost, unproven benefit.
11. Make the site fast. A page that loads quickly is easier for people and crawlers alike. Check it with PageSpeed Insights.

How to test what AI says about you

Once a month, ask the same short list of questions in ChatGPT, Google (with AI Overviews or AI Mode), Claude, Perplexity and Copilot, ideally signed out or in a private window. Use the questions a customer would ask, for example:

• "Who are the best [your trade] companies in [your town]?"
• "What does [your business name] do and where do they work?"
• "How much does a [your service] cost in [your county]?"

Write down whether you were named, whether the facts were right, and which other sites were cited. When an answer is wrong, find the page it should have used and make the right fact clearer there. When a competitor is cited, look at what their page has that yours doesn't. Keep the log; the trend over months matters more than any single answer.

What we did on this site, as of 27 October 2026: robots.txt allows every crawler, including the AI search crawlers, and states a Content-Signal line allowing search, AI input and AI training; /llms.txt and /llms-full.txt are generated from the pages on every build; and our AI facts page dates each fact. Our AI-answer scorecard method is public, so you can see exactly how we score what assistants say.
