Short answer: GEO stands for generative engine optimization. It means making the public information about your business easy for AI search tools to find and repeat correctly – tools like ChatGPT search, Perplexity, Google's AI Overviews and Microsoft Copilot. Nobody can buy or guarantee a recommendation, and a single mention in an AI answer does not prove you will get more work.
The term is newer than the work behind it. Most of what helps in AI answers is the same groundwork that helps in ordinary search: a website that can be crawled and indexed, clear facts in plain text, and consistent business details. This guide explains what GEO covers, what you can do yourself and how to check results without fooling yourself. The short definition is also in our glossary entry on GEO.
SEO and GEO: related, but not the same question
SEO asks whether your pages appear in search results. GEO adds a second question: when someone asks an AI assistant, is your business mentioned, recommended, or linked as a source – and are the details correct? Those are separate events and worth recording separately.
Google says there are no additional technical requirements for appearing in AI Overviews or AI Mode. A page must be indexed and eligible to show with a snippet in Google Search, and even then nothing is guaranteed. Google also says you do not need special AI text files, new machine-readable files or special schema.org markup for its AI features. [1]
How AI search tools get their information
AI assistants with web search look up current pages for a question and cite some of them. The providers document the basics themselves:
- ChatGPT: OpenAI uses the crawler OAI-SearchBot for ChatGPT's search features. According to OpenAI, sites that block OAI-SearchBot will not be shown in ChatGPT search answers. A separate crawler, GPTBot, relates to model training. [2]
- Perplexity: PerplexityBot surfaces and links websites in Perplexity's search results, and Perplexity recommends allowing it. [3]
- Google: AI Overviews and AI Mode draw on pages that are indexed and eligible for a snippet in Google Search. [1]
- Microsoft Copilot and Bing: Since February 2026, Bing Webmaster Tools has a public-preview report called AI Performance that shows how often your pages are cited as sources in Copilot and Bing's AI-generated answers. [4]
What you can actually improve
Start with the information your customers rely on. This work is worthwhile even if no AI tool ever cites your site.
- Describe your services, service area, who you work for and how to reach you – clearly and currently, in text on the page, not only in images or PDFs.
- Fix contradictory details on your own pages and on profiles you legitimately control. Don't buy directory listings just to create more mentions.
- Check with whoever runs your site that robots.txt, firewall or CDN settings don't block search crawlers by accident, and that important pages aren't set to noindex.
- Answer real customer questions and back up technical claims with suitable sources. Microsoft recommends clear headings, tables, FAQ sections, claims supported by sources, and keeping content up to date. [4]
- Don't replace genuine reviews and editorial mentions with bought reviews or link swaps.
Keep the systems apart
ChatGPT search, Perplexity, Gemini, Copilot and Google's AI Overviews are different products. The search setting, account, region and model can all change the answer. Don't quietly compare an API response without web search to an answer a customer sees in an app with search switched on.
A measurement you can repeat later
- Decide on your questions, language, location and system before you start.
- Test questions without your business name (“Who installs water heaters in [town]?”) separately from questions about your business (“What does [business name] offer?”).
- Record the question, date, system and model where shown, app or API, search mode and location context.
- Save the original answer and the linked sources. Score mention, recommendation, source citation and correct business details separately.
- Repeat with the same settings. Describe changes, but don't automatically credit them to something you did.
Not being mentioned means: not mentioned in this sample. It does not prove that you are invisible everywhere or that you lost work.
A simple figure, calculated correctly: if your business is named in one of eight answered questions, the observed mention rate is 12.5% (1 ÷ 8). That is not a general visibility score. Write down the denominator, check that the questions are relevant, and record errors separately. Whether you gain revenue is something only your actual calls, inquiries and jobs can show.
Frequently asked questions
Does GEO guarantee that AI tools will recommend my business?
No. You can improve your information and watch the results, but nobody can promise inclusion in answers that another company's system generates.
Do I need a special file or markup for AI search?
Not for Google's AI features: Google says the usual Search requirements apply and no special files or markup are needed. An llms.txt file is a proposed convention; how AI providers use it is not documented in a binding way, so treat it as optional.
How long does GEO take to work?
There is no reliable standard timeframe. OpenAI and Perplexity say robots.txt changes can take up to about 24 hours to take effect, but whether and when your content shows up in answers is decided by each system.

Want to know whether the groundwork is in place? Request the free website audit – a written review of your website and Google Business Profile with practical suggestions, by email, no obligation. If you want the full picture, the Visibility Analysis checks up to 25 pages, structured data, crawler rules, business details and competitors and gives you a 30/60/90-day plan. To work through it yourself, the AI Search Starter Kit in our shop explains what each AI system needs to know about your business. None of these measure or guarantee AI mentions.
General information, not legal advice. Google, Microsoft, OpenAI and Perplexity change their products and help pages; the linked sources in their current version take precedence.
