Generative engine optimization (GEO) is the practice of making your content easy for AI answer engines (ChatGPT search, Perplexity, Claude, Gemini and Google's AI Overviews) to find, trust and quote. Classic SEO earns you a blue link. GEO earns you a citation inside the answer.
The good news is that GEO is not a separate discipline. Every major AI engine still retrieves from a web index, so pages that cannot be crawled or ranked rarely get cited. GEO is SEO plus a set of habits that make each passage extractable. This is the checklist we apply to our own site and to client sites.
GEO vs SEO vs AEO: what is the difference?
| SEO | AEO (answer engine optimization) | GEO | |
|---|---|---|---|
| Goal | Rank a page in search results | Win the direct answer (featured snippet, voice) | Be quoted or cited in AI-generated answers |
| Unit that wins | The page | One short answer | A self-contained passage plus a trusted entity |
| Key signals | Relevance, links, technical health | Direct answers, question headings, FAQ schema | Everything on the left, plus clear entities, freshness and third-party mentions |
Step 1: Make sure AI crawlers can actually read you
- Allow the AI crawlers in robots.txt: GPTBot and OAI-SearchBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, Google-Extended and Applebot-Extended. Blocking them removes you from the candidate pool.
- Serve real HTML. Many AI crawlers do not run JavaScript. If your site is a single-page app, pre-render or server-render it so the text is in the initial HTML. We had to do exactly this for our own Angular site.
- Publish an
llms.txtat your root: a plain-language summary of who you are and links to your most important pages. - Keep a clean sitemap with accurate
lastmoddates.
Step 2: Write answer-first, extractable passages
AI engines lift passages, not pages. Write so that any single section still makes sense when it is quoted on its own.
- Put the answer in the first one or two sentences under each heading. Explain afterwards.
- Use the question as the heading. For example "How much does X cost?" rather than "Pricing considerations".
- Name things explicitly. Repeat the subject instead of writing "it" or "this tool", so a quoted sentence stays clear.
- Use tables for comparisons and numbered lists for steps. Both are easy to extract.
- Give specifics: ranges, thresholds, dates and named methods. Vague advice is rarely quoted.
- Add a TL;DR at the top of long articles.
Step 3: Add structured data that defines your entity
- Organization schema with your name, logo, URL and
sameAslinks to your LinkedIn and other official profiles. This is how engines tie mentions back to you. - Article / BlogPosting with author, publish date and modified date.
- FAQPage for genuine question-and-answer sections.
- Product, Service and BreadcrumbList where they apply.
Structured data does not guarantee a citation, but it removes ambiguity about who said what and when.
Step 4: Earn information gain
An AI answer that already knows the generic facts has no reason to cite a page that repeats them. Pages that get quoted add something new:
- Your own data, such as prices you charge, timelines you have delivered, or results you have measured.
- A named framework or decision checklist.
- A clear opinion on a trade-off ("choose A when…, choose B when…").
- Practitioner detail that only someone who has done the work would know.
Never invent statistics to look authoritative. Unsupported numbers erode trust with readers and with the systems that rank you.
Step 5: Build third-party corroboration
AI engines lean on consensus. When several independent sources describe your business the same way, the model is more confident naming you. Practical sources:
- Accurate, consistent listings on review platforms and business directories.
- Guest articles and podcast appearances on sites in your niche.
- Genuine answers on community sites where your buyers ask questions.
- Partner and integration pages that link to you.
Step 6: Keep content fresh and measure it
- Review your key pages every quarter and update facts, prices and the modified date. Only change the date when the content really changed.
- Track AI referrals in analytics: traffic from chatgpt.com, perplexity.ai and similar domains.
- Ask the engines your buyers' questions monthly and record whether you are cited and which page they quote.

Frequently asked questions
What is generative engine optimization?
Generative engine optimization (GEO) is the practice of structuring and publishing content so AI answer engines like ChatGPT, Perplexity and Google AI Overviews can find it, trust it and cite it in their responses.
Is GEO replacing SEO?
No. AI engines retrieve from web indexes, so strong technical SEO and relevance remain the foundation. GEO adds extractable, answer-first writing, clear entity markup and third-party corroboration on top.
How do I get my website cited by ChatGPT?
Allow OpenAI's crawlers in robots.txt, make sure your text is in server-rendered HTML, answer questions directly under question-style headings, mark up your organization with schema, and earn mentions of your brand on other reputable sites.
What is llms.txt?
llms.txt is a plain-text file at the root of a website that summarises what the site is about and links to its most important pages, to help language models understand and navigate it. It is a proposed convention, not a ranking guarantee.
How long does GEO take to work?
Technical fixes can be picked up within weeks of the next crawl. Authority signals, such as third-party mentions and a history of being cited, build over months.
