Generative engine optimization (GEO) is the work of making your content easy for AI search tools to find, understand and cite when they answer a question. Those tools include Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Gemini and Microsoft Copilot. GEO sits on top of SEO. It does not replace it.
This guide explains how AI answers choose sources, what actually helps, how to check whether you are being mentioned, and a 30-day plan you can follow. It also says plainly what is unproven, because a lot of advice about AI search is guesswork presented as fact.
- AI answers are built from pages that are already crawlable, indexed and considered credible. Technical SEO comes first.
- Put a direct, specific answer at the top of each section. Vague copy is rarely quoted.
- Keep your business facts identical everywhere: website, Google Business Profile, directories, social profiles.
- Mentions on other reputable sites matter. GEO is partly an off-site job.
- Test by asking the questions your customers ask, and record what the AI tools say.
GEO, AEO and SEO: how they relate
Definitions vary between agencies, and no standard exists. This is a practical way to separate them:
| SEO | AEO | GEO | |
|---|---|---|---|
| Goal | Rank in the list of results | Be the direct answer (snippets, People Also Ask, voice) | Be cited or named inside a generated AI answer |
| Main lever | Crawlability, relevance, links, page experience | Clear question-and-answer structure | Clarity, specificity and third-party corroboration |
| Where you see it | Search results page | Featured snippet, PAA, assistants | AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini, Copilot |
| Typical metric | Rankings, clicks | Snippet ownership | Mentions and citations across a set of test questions |
Because the same pages feed all three, we run them as one program. Our overview of AEO and GEO for AI search covers the service side, and how to rank in Google AI Overviews goes deeper on Google specifically.
How AI answers choose which sources to cite
Most AI search products work in two steps. First a retrieval step finds relevant pages, often by running several related searches at once. Then a language model writes an answer using the retrieved material and shows some of the sources. Three consequences follow:
- You cannot be cited if you are not retrieved. The page must be crawlable, indexed and relevant to the question, which is ordinary SEO.
- The model prefers passages it can lift cleanly. A section that opens with a self-contained answer is easier to use than a story that reaches its point in paragraph five.
- Corroboration matters. When several independent sources agree on who you are and what you do, an answer is more likely to include you.
Google is explicit that appearing in AI Overviews and AI Mode does not need special optimization or extra files: its guidance is that the same SEO best practices apply (see Google’s documentation on AI features and your website). Other vendors publish less, so treat any claim of a secret ranking factor with suspicion.
What actually helps
1. Make sure AI crawlers can reach your pages
Check robots.txt, your CDN and your firewall. Overzealous bot protection sometimes blocks legitimate crawlers such as OAI-SearchBot (used for ChatGPT search), PerplexityBot and Bingbot. Note that Google-Extended controls whether Google may use your content for Gemini training and grounding, and it does not affect inclusion in Google Search. Whether to allow each crawler is a business decision: allowing search-focused crawlers is what makes citation possible. Our technical SEO guide covers crawl and index checks in full.
2. Answer the question first, then explain
Under each question-shaped heading, give the answer in the first one or two sentences, then add the reasoning, an example and the exceptions. This helps human readers just as much, which is why it is worth doing even if you are sceptical about AI.
3. Be specific enough to be worth quoting
Compare “we offer affordable web design” with “a typical five-page clinic website takes two to three weeks and we quote a fixed price after a discovery call”. The second gives a model, and a reader, something concrete. Use real prices or ranges, timelines, locations, named tools and honest limits. Do not invent statistics; a made-up number that gets quoted will hurt you.
4. Keep your entity facts consistent
Use the same business name, service descriptions, contact details and profile links on your website, Google Business Profile, LinkedIn and directories. If sources disagree, systems have less reason to trust any of them. Our guide to Google Business Profile optimization shows what to align.
5. Earn mentions off your own site
Reviews, local and industry directories, interviews, guest articles and citations from reputable sites all act as independent confirmation. This is the slow part, and it is why GEO cannot be finished in a weekend. See our link building guide for practical, non-spammy approaches.
6. Use structured data as clarification, not a trick
Organization, Service, Article and FAQPage markup that matches visible content helps machines parse your pages. It is not a requirement for AI features and it is not a shortcut. Details in our schema markup guide.
7. Keep important pages current
Update prices, dates and processes when they change and show an honest “last updated” date. Stale facts are one of the easiest ways to be excluded or misquoted.
What about llms.txt?
llms.txt is a proposed plain-text file that summarizes a site for language models. No major search engine has confirmed that it uses it, so it should not be sold as a ranking factor. It costs little to publish, and we keep one on this site as an optional resource, but it is not where the results come from.
How to check whether AI tools mention your business
You do not need an expensive tool to start. Use a simple, repeatable test:
- Write 15 to 20 questions your real customers ask, for example “which dentist near me does Invisalign” or “how much does an ecommerce website cost in India”. Include a mix of research questions and buying questions.
- Run each question in the AI tools your customers use. Use a fresh session and, where possible, not your own logged-in account.
- Record whether your business is named, whether your website is cited, which page was cited and which competitors appear.
- Repeat monthly on the same list. Answers change from run to run, so read the pattern over time, not a single result.
| Question | Tool | We are named? | Our page cited? | Who else appears? |
|---|---|---|---|---|
| Example: best dental website design for Canadian clinics | ChatGPT / Perplexity / AI Mode | Yes / No | URL or none | List the names |
A 30-day GEO starter plan
| Week | Focus | Output |
|---|---|---|
| 1 | Crawl and index health | Fix blocked crawlers, broken links, noindex mistakes and sitemap errors. Confirm key pages are indexed in Search Console. |
| 2 | Answer-first rewrites | Rewrite the top five money pages so each section opens with a direct answer, real numbers and honest limits. |
| 3 | Entity consistency | Align business name, services and contact details across the site, Google Business Profile, LinkedIn and directories. Add accurate Organization and Service markup. |
| 4 | Test and plan | Run your question list, record the baseline, then pick two pages and two third-party sources to improve next. |
Common GEO mistakes
- Blocking crawlers by accident through a CDN, firewall or copied robots.txt rules.
- Writing “AI-friendly” filler. Padding a page with generic definitions gives models nothing they cannot get elsewhere.
- Hiding key content in scripts or images so it is not in the HTML crawlers receive.
- Contradicting yourself. Different prices, services or addresses on different pages.
- Mass-producing FAQ pages for every keyword variation. One good FAQ on the right page beats fifty thin ones.
- Promising guaranteed AI rankings. Nobody can.
GEO for local and service businesses
For clinics and other local providers, AI answers to “who is a good dentist near me” lean heavily on Google Business Profile data, reviews and clear service pages. A dental clinic should get its local SEO and dental SEO foundations right before spending on anything AI-specific.

Frequently asked questions
What is GEO in SEO?
GEO (generative engine optimization) is the practice of making your pages easy for AI answer tools such as Google AI Overviews and AI Mode, ChatGPT search, Perplexity, Gemini and Copilot to find, understand and cite. It builds on classic SEO: the page must be crawlable and indexed, the answer must be clear and specific, and your business identity must be consistent across your site and the wider web.
Is GEO different from AEO?
The terms overlap and there is no industry standard. Many SEOs use AEO (answer engine optimization) for featured snippets, People Also Ask and voice answers, and GEO for citations inside generated AI answers. The practical work is largely the same: clear answers, strong topical coverage, accurate facts and trustworthy sources.
Does GEO replace SEO?
No. AI answer tools mostly retrieve pages from search indexes, so a page that is not crawlable, indexed and credible has little chance of being cited. GEO adds a layer on top of SEO; it does not replace technical SEO, content quality, internal linking or authority.
Do I need schema markup or llms.txt to appear in AI answers?
Google states that no special markup or extra files are required to appear in AI Overviews or AI Mode, and no major search engine has confirmed that it relies on llms.txt. Schema markup is still worth adding where it accurately describes visible content because it removes ambiguity for machines. Treat llms.txt as an optional, low-cost extra, not a ranking lever.
How can I check whether ChatGPT or Perplexity mentions my business?
Write 15 to 20 questions a real customer would ask, run each in the AI tools you care about, and record whether your business is mentioned, whether your site is cited and which competitors appear. Repeat monthly. Answers vary from run to run, so look for patterns over several runs, not a single result.
Can anyone guarantee that AI tools will recommend my business?
No. The models and the retrieval systems behind them decide, and they change often. What a provider can do is remove technical barriers, publish clear and specific content and strengthen the third-party signals that show your business is real. Be cautious of anyone who promises a guaranteed AI ranking.
