What Is Generative Engine Optimization (GEO)?

Direct Answer

Generative Engine Optimization (GEO) is the strategy of optimizing content to be cited by AI-powered chatbots and generative search engines — specifically ChatGPT, Perplexity, Google's AI Overviews, and similar platforms. Unlike traditional SEO which targets ranking positions, GEO targets being included as a source in AI-generated responses that users read and trust.

The Short Answer

GEO is the newest evolution of SEO. While AEO focuses on extracted answers in search results, GEO specifically targets the generative AI engines that are becoming primary information sources for millions of users. When someone asks ChatGPT "what's the best SEO tool for content?", GEO is what determines whether your brand gets mentioned in the response.

How GEO Works

The AI Citation Pipeline

Generative AI engines work differently from traditional search. When a user asks a question, the AI: (1) identifies the topic, (2) retrieves relevant web content using embedded search, (3) synthesizes information from multiple sources, and (4) generates a response with optional citations. GEO optimizes each step — making your content discoverable, extractable, and citation-worthy.

GEO Optimization Checklist

1. Publish llms.txt — Guide AI crawlers to your key content
2. Allow AI crawlers in robots.txt — GPTBot, PerplexityBot, ClaudeBot
3. Include quotable statistics — AI engines love specific numbers and data points
4. Write definitive definitions — Clear, concise definitions are highly citable
5. Structure with schema markup — FAQPage, Article, Speakable
6. Build topical authority — AI engines prioritize established expert sources
7. Keep content current — Fresh content with recent dates gets cited more

Frequently Asked Questions

AEO focuses on being the answer in featured snippets and AI Overviews. GEO specifically targets generative AI engines (ChatGPT, Perplexity, Claude) that synthesize responses from multiple sources and include citations.

Produce authoritative, well-structured content on topics ChatGPT frequently discusses. Use clear formatting, include unique data, and publish on domains with established authority. ChatGPT uses web browsing to find current, credible sources.

GEO builds on SEO fundamentals but adds a layer focused on AI citation. Key differences include optimizing for comprehensive answers (not just keywords), including quotable statistics, and using llms.txt for AI crawler guidance.

llms.txt is a file placed in your site's root directory that helps AI crawlers understand your site's structure and find key content. Think of it as robots.txt for AI engines.

Track brand mentions in AI chatbot responses, monitor referral traffic from AI platforms (e.g., chat.openai.com in analytics), and use tools that track AI engine citations across ChatGPT, Perplexity, and Google AI Overviews.
