GEO (Generative Engine Optimization)

GEO (Generative Engine Optimization) is the set of techniques designed to get a brand, product or piece of content cited by generative engines such as ChatGPT, Perplexity, Gemini and Google's AI Overviews. Its goal isn't the click, but the mention inside the AI's answer.

GEO (Generative Engine Optimization) is the discipline of structuring content so it gets picked up, summarized and cited by generative engines — ChatGPT, Perplexity, Gemini, Claude and Google's AI Overviews. Where SEO seeks the click through to your site, GEO seeks the mention of your brand inside the answer the AI generates.

Why GEO changes the game

When a user asks ChatGPT a question, they no longer get ten blue links but a single, synthesized answer. If your brand isn't in that answer, it doesn't exist for that user. GEO works on the signals that lead an AI to choose your content as a source: self-contained passages of around 150 words, definitions in the "X is…" format, original data, and off-site presence (YouTube, Reddit, Wikipedia) that weighs heavily on the citation decision.

A concrete example

An agency that publishes a clear, data-backed definition of "AI share of voice" in a citable block stands a good chance of being quoted word for word when a user asks Perplexity "what is AI share of voice?". The content becomes the answer, not just one link among many.

Why it matters for your visibility

GEO isn't one more channel: it's the new front door to search. It works hand in hand with AEO, builds on E-E-A-T, and is deployed through a GEO seeding strategy. To structure this approach, discover our GEO agency.

Key takeaway

GEO doesn't replace SEO, it extends it. Without solid, citable pages, no AI will mention you.

FAQ

Frequently asked questions

No. GEO builds on SEO: most AI Overview citations come from pages that already rank well on Google. SEO remains the foundation, and GEO leverages its reach across generative AI.

You track how often the brand is cited in answers from ChatGPT, Perplexity and Gemini across a panel of target queries — this is AI share of voice, not traffic alone.
