What Is Generative Engine Optimization (GEO)? How to Get Your Business Recommended by ChatGPT and AI Search

Generative engine optimization (GEO) is the work of making your business easy for AI assistants such as ChatGPT, Perplexity, Microsoft Copilot and Google's AI Overviews to find, understand and cite when someone asks for a recommendation. It builds on SEO: the assistant still has to reach your pages, trust them and quote them. Nobody can guarantee a mention, but you can make your business the clearest, best-sourced answer available.

This brief is for business owners, marketers and agencies who want their business named when a customer asks an AI assistant “who is the best ... near me?” or “which tool should I use for ...?”. It is the pillar of a GEO series on this blog: five moves, each with what to do and how to check it.

Move 01 · Define

What is GEO, and how is it different from SEO?

The term comes from a 2024 research paper by Pranjal Aggarwal and colleagues at IIT Delhi and Princeton University, presented at the ACM KDD conference. They define a generative engine as a system that retrieves sources and writes one synthesized answer with citations. SEO competes for a position on a results page. GEO competes for a place inside the answer itself.

The two overlap heavily. Google's own guidance, updated July 10, 2026, says optimizing for its AI features “is optimizing for the search experience, and thus still SEO.” Its AI Overviews and AI Mode draw on the same Search index and ranking systems, and they run several related searches at once (Google calls this query fan-out) to build an answer. So GEO is not a replacement for SEO. It is SEO with a sharper focus on being quotable, specific and trustworthy.

Move 02 · Access

Can ChatGPT, Perplexity and Google actually reach your website?

The important distinction is between search crawlers, which decide whether you can appear and be linked in answers, and training crawlers, which collect content for future models. You can allow one and block the other.

OpenAI and Perplexity both say a robots.txt change can take about 24 hours to take effect. Google adds one more control: since its June 3, 2026 announcement, rolled out worldwide by August 31, 2026, Search Console has a single toggle to opt a site out of AI Overviews and AI Mode. Leave it on if you want to be recommended. For reference, check the OpenAI crawler documentation here and the Perplexity crawler documentation here.

Move 03 · Write

What kind of content do AI answers quote?

The GEO paper tested nine ways of rewriting a web page on its GEO-bench set of 10,000 queries and measured how much of each source made it into the generated answer, weighted by position. The results are a useful guide to what helps and what does not.

In practice, that translates into four habits for every important page:

1. Answer first. Open with two or three sentences that answer the page's question and still make sense when quoted alone.
2. Add facts with sources. Prices, service areas, hours, years in business, policies: state them plainly, with a date, and link the source when a claim comes from someone else.
3. Quote real authorities. A short, attributed quote from a regulator, a standard or a recognised expert gives the assistant something it can cite.
4. Use questions as headings. Phrase sections the way customers ask, and keep each section understandable on its own.

Google adds two warnings worth taking seriously. It says you do not need special AI text files, extra markup or Markdown versions to appear in its AI features, and that its Search ignores llms.txt files. It also says that spinning up a page for every variation of a question to manipulate AI answers breaks its scaled content abuse policy. For reference, check Google's optimization guide here. How your own AI agent uses the same kind of clear knowledge is covered in RAG for business knowledge.

Move 04 · Presence

Where else do AI assistants look for your business?

Google's guide names Google Business Profile and Merchant Center as ways to improve visibility in its AI responses. For a local service business, the profile is often the first thing an AI answer draws on: categories, hours, service area, photos and reviews. Bing Places plays the same role for Microsoft's results. Beyond listings, assistants read directories, industry associations, news coverage and review sites.

Consistency matters because an assistant that finds three different descriptions of your business has less reason to trust any of them. This is also why customer experience shows up in AI answers: reviews are public text, and assistants read them. Fast, useful replies in chat help here too, which is covered in AI chatbots for small businesses.

Move 05 · Measure

How do you know whether AI assistants recommend your business?

Two search companies now report AI visibility to site owners. Bing Webmaster Tools added an AI Performance report in public preview on February 10, 2026: it shows total citations, the average number of your pages cited and the grounding queries the AI used, across Microsoft Copilot, AI summaries in Bing and select partners. Google Search Console is rolling out data on impressions and which pages appear in its AI responses, by country. Both are free once your site is verified.

Success metric: mention rate across a fixed set of ten customer questions in ChatGPT, Perplexity, Google AI Mode and Copilot, checked monthly, alongside cited pages in Bing's AI Performance report. Watch the trend over three months, not a single result.

An honest limitation: no one controls what an AI assistant says. Answers change with the wording of the question, the user's location and history, and each company's model updates. The GEO paper's figures come from controlled tests on its own benchmark, not from guaranteed results on live assistants, and Google says no third-party tool has access to its ranking or AI systems. Treat anyone who promises a guaranteed ChatGPT recommendation with caution.

Frequently asked questions

What does GEO stand for?

Generative engine optimization: improving how often and how prominently AI assistants such as ChatGPT, Perplexity, Copilot and Google's AI Overviews mention and cite your business or content in their answers.

Is GEO different from SEO?

It overlaps heavily. AI search features rely on search indexes and ranking systems, so SEO basics still apply. GEO adds a focus on being quotable: clear answers, sourced facts and consistent information across the web.

Do I need an llms.txt file to appear in AI answers?

Not for Google. Its guidance, updated July 10, 2026, says Google Search ignores llms.txt and that no special AI files or markup are needed to appear in its AI features.

Can I pay to be recommended by ChatGPT?

No one can buy or guarantee an organic recommendation inside an AI answer. Ads are a separate, labelled product. The reliable route is being reachable, clear, well-sourced and consistently listed.

How long does GEO take to work?

Crawler access changes can apply within about 24 hours, according to OpenAI and Perplexity. Content and listing improvements usually need several weeks of recrawling, so measure the trend over three months.
