GEO, AEO and AIO Explained: How Local Businesses Get Recommended by ChatGPT and Google's AI Overviews

A few years ago, being found online meant one thing: ranking on the first page of Google. Today, a growing number of customers never scroll through a list of links. They read Google's AI Overview at the top of the page, or they ask ChatGPT, "Who's a good dentist in Buckhead?" and call whichever businesses it names.

That shift has produced a new set of terms: GEO, AEO, and AIO. They can sound like jargon, but the ideas behind them are practical. This guide explains each term in plain English, what the major platforms actually say about how they choose sources, and what a local business can do to be included.

The three terms, in plain English

GEO: Generative Engine Optimization. Making your business and content easy for generative AI tools, like ChatGPT, Google's AI Mode, Perplexity, and Microsoft Copilot, to find, understand, and cite when they write an answer.

AEO: Answer Engine Optimization. Structuring your content so it directly answers the questions people ask, whether the answer appears in a featured snippet, a voice assistant response, or an AI-generated summary.

AIO: AI Optimization, also used to mean optimizing for Google's AI Overviews. In practice it covers the same ground: being a source that AI features trust and link to.

The three overlap heavily. The common thread is this: AI tools summarize information from sources they can access and trust. Your goal is to be one of those sources.

What the platforms actually say

It helps to start with what Google and OpenAI have published, rather than rumors.

Google AI Overviews and AI Mode. Google's guidance for site owners says the same SEO best practices apply to AI features as to Search overall. To be eligible as a supporting link, a page must be indexed and eligible to be shown in Google Search with a snippet, and there are no additional technical requirements. Google also recommends allowing crawling, using internal links, making important content available as text, keeping structured data consistent with the visible page, and keeping your Business Profile up to date.

ChatGPT search. OpenAI uses a crawler called OAI-SearchBot to surface websites in ChatGPT's search features. Sites that block OAI-SearchBot in robots.txt won't be shown in ChatGPT search answers. OpenAI has also said ChatGPT search draws on third-party search providers, which is why being well indexed by search engines like Bing matters too, not just Google.

The takeaway is reassuring: there's no secret trick. AI visibility rests on the same foundations as good search visibility, with a few extra areas of emphasis.

Seven things local businesses can do

1. Make sure AI crawlers can reach your site

Check your robots.txt file and any security or CDN settings. Googlebot, Bingbot, and OAI-SearchBot should be allowed. A surprising number of sites block AI crawlers by accident through a firewall setting or a template default.

2. Get indexed in both Google and Bing

Verify your site in Google Search Console and Bing Webmaster Tools, submit your sitemap to both, and fix indexing errors. Bing also supports IndexNow, which lets your site notify participating search engines as soon as a page changes.

3. Put your important information in text

AI tools need to read your content. Your services, service areas, hours, pricing approach, and contact details should be written out on the page, not only in images, PDFs, or features that load only after a click. Make sure the full content appears in the page's HTML for crawlers that don't run JavaScript.

4. Answer real questions directly

Think about the questions customers ask before they call you: "How much does a crown cost?", "Do you work in Marietta?", "How fast can you come out after a storm?" Answer them on your site in clear, direct language. Lead with the answer, then explain. FAQ pages and short guides like this one are natural sources for AI summaries.

5. Be consistent about who you are

AI tools cross-check facts. If your business name, phone number, or service area differs between your website, Google Business Profile, Bing Places, social profiles, and directories, it's harder for them to describe you confidently. Pick one version of your details and use it everywhere.

6. Use structured data that matches the page

Structured data, such as LocalBusiness, Service, FAQPage, and Article markup, helps search engines understand your content. Google is clear that it should match what visitors can see on the page. Don't mark up reviews, prices, or claims that aren't actually shown.

7. Show real expertise and real reviews

AI answers about local businesses tend to reflect what the web says about them. Detailed service pages, author bios that show real experience, genuine customer reviews, and mentions on reputable local sites all strengthen the picture. Avoid inflated claims; they undermine trust with both people and machines.

What about llms.txt?

llms.txt is a proposed format: a plain-text file at the root of your site that gives AI tools a short, organized guide to your most important pages. It's cheap to add and can't hurt, but it isn't a requirement, and Google says its AI features need nothing beyond normal Search requirements. Treat it as a helpful extra on top of a well-built, crawlable site, not a shortcut.

How to measure AI visibility

AI visibility is harder to measure than rankings, but you're not working blind:

  • Google Search Console includes clicks and impressions from AI Overviews and AI Mode in the Performance report, under the Web search type.
  • Analytics referrals from chatgpt.com, perplexity.ai, copilot.microsoft.com, and similar sources show visits from AI tools.
  • Regular spot checks. Each month, ask ChatGPT, Google, and Copilot the questions your customers would ask, like "best HVAC company in Alpharetta," and note whether and how your business appears.
  • Calls and form submissions. Ask new customers how they found you, and include "an AI tool like ChatGPT" as an option.

Where to start

If you do only three things this month:

  1. Confirm that your site is indexed in Google and Bing and that AI crawlers aren't blocked.
  2. Rewrite your main service pages so they answer customers' top questions in clear text.
  3. Make your business name, phone number, and service area identical everywhere they appear.

Those steps help with traditional search, AI Overviews, and ChatGPT at the same time.

Frequently asked questions

Is GEO different from SEO?

GEO builds on SEO rather than replacing it. Google says pages need to be indexed and eligible to show a snippet to appear in AI Overviews, so SEO fundamentals come first. GEO adds a focus on clear, quotable answers and consistent business information that AI tools can confidently summarize.

How do I get my business mentioned by ChatGPT?

Make sure your site allows OpenAI's search crawler, OAI-SearchBot, in robots.txt, and that it's indexed by major search engines, since ChatGPT search also uses third-party search providers. Then publish clear, accurate information about your services, location, and expertise, and keep your details consistent across the web.

Do I need an llms.txt file?

It's optional. llms.txt is a proposed format that gives AI tools a short guide to your site. Google has said AI Overviews need nothing beyond normal Search requirements, so treat llms.txt as a low-cost extra, not a substitute for a well-built, crawlable website.

How can I tell if AI search is sending me traffic?

Google Search Console includes clicks from AI Overviews and AI Mode in its Performance report under the Web search type. You can also check referral traffic from chatgpt.com and other AI tools in your analytics, and regularly ask AI tools the questions your customers would ask.
