Generative Engine Optimization (GEO): How to Get Cited by ChatGPT, Gemini and Claude

People are asking ChatGPT, Gemini, Claude and Perplexity the questions they used to type into Google, and Google itself now shows AI Overviews above the regular results. These answers often cite a handful of sources. Generative engine optimization (GEO) is the practice of making your content easy for AI systems to find, understand, trust and quote.

GEO does not replace SEO. Many AI search features still rely on traditional search indexes, so a page that is not crawlable or not ranking anywhere is unlikely to be cited. Think of GEO as SEO plus a stronger focus on clear answers, verifiable facts and brand consistency.

Key takeaways

Generative engine optimization is the process of structuring content and building authority so that large language model (LLM) based tools, such as ChatGPT search, Google Gemini and AI Overviews, Claude and Perplexity, select your page as a source when they generate an answer.

Each product works differently and none publishes a full ranking formula, but the patterns are consistent:

1. Retrieval first. When an assistant searches the web, it pulls candidate pages from a search index. If your page is not indexed or is blocked, it cannot be picked.
2. Answer fit. The model looks for passages that directly answer the user's question. A clear two to three sentence answer under a matching heading is easy to lift.
3. Trust signals. Recognised brands, named authors with real expertise, and facts that match other reputable sources are safer to quote.
4. Freshness. For topics that change (tools, prices, regulations), recently updated pages have an edge.

1. Put the answer first. Start each key section with a one or two sentence answer, then expand. AI tools often quote the opening lines of a section.

2. Write headings as real questions. Use the words people actually ask: "What is a postback URL?", "How much do affiliate marketers make?". This matches conversational prompts.

3. Use tables and lists for comparisons. Structured comparisons (pricing models, pros and cons, steps) are easy for models to extract accurately.

4. Add specific, verifiable facts. Cite official documentation, regulations or your own data. Avoid vague claims like "most marketers agree". Specific and sourced beats general.

5. Publish original insight. Your own benchmarks, case studies and process explanations give AI tools something they cannot find elsewhere, which makes your page a natural citation.

6. Show who wrote it. Add an author with a real bio, role and experience. Experience and expertise signals matter to both Google and AI systems.

7. Keep your brand consistent everywhere. Use the same company description, services and positioning on your website, LinkedIn, Google Business Profile, directories and partner pages. Models learn what your brand is from repeated, consistent mentions.

8. Get mentioned on trusted third-party sites. Industry publications, partner blogs, podcasts and community discussions build the authority that makes models comfortable recommending you.

9. Keep technical SEO healthy. Fast pages, clean HTML, structured data (Article, FAQ, Organization) and an accurate XML sitemap help every crawler, including AI ones.

AI companies use named crawlers, for example OpenAI's GPTBot and OAI-SearchBot, Anthropic's ClaudeBot and Google's Google-Extended control for Gemini. You control them in robots.txt.

• If you want to be cited in AI answers, do not block the search-related crawlers that power those answers.
• Blocking training crawlers is a business decision; it may not stop your pages appearing in AI search, because search features can use separate crawlers.
• Check each provider's current documentation before changing rules, as crawler names and behaviour are updated over time.

You may also see llms.txt mentioned. It is a proposed file that summarises your site for LLMs. Adoption by major assistants is not confirmed, so treat it as optional rather than essential.

• AI referral traffic: in Google Analytics, look for sessions from chatgpt.com, gemini.google.com, perplexity.ai, claude.ai and similar referrers.
• Prompt testing: keep a list of 20 to 30 questions your buyers ask and check monthly which brands the assistants mention.
• Brand mentions: track unlinked mentions of your brand across the web.
• Search Console: AI Overviews traffic is included in your Google Search performance data.

• Writing long introductions before answering the question.
• Publishing AI-generated filler with no new information.
• Different company descriptions on different platforms.
• Blocking crawlers by accident through security or CDN settings.

Generative engine optimization rewards the same thing good marketing always has: being the clearest, most trustworthy answer to a real question. Start with your top revenue topics, rewrite them answer-first, add original facts and make sure your brand story is consistent everywhere.
