What Is GEO (Generative Engine Optimization)?

Short answer: GEO (Generative Engine Optimization) is the practice of getting your brand mentioned in the answers produced by AI engines like ChatGPT, Gemini, Google AI Overviews and Perplexity. The core difference from SEO is economic: a search result page has ten links and ranking third still brings traffic; an AI answer typically mentions zero or one brand — a brand that isn't mentioned simply doesn't exist for that user. GEO work runs on three layers: technical access (AI crawlers can read your site), quotable content (self-contained passages answering clear questions), and entity building (your name appearing consistently across the web). Its metrics are concrete: mention rate on category questions, share of voice against competitors, and the sources the model cites. GEO doesn't replace SEO — it builds on the same foundations; a site with poor SEO has no GEO, but a brand with good SEO and no AI visibility now loses customers every day.

GEO (Generative Engine Optimization) is the practice of getting your brand cited and recommended as a source in the answers produced by generative AI engines like ChatGPT, Gemini, Google AI Overviews and Perplexity. SEO lifts you up the search results; GEO aims to place your brand inside the single answer AI gives.

Why has search changed?

People no longer look for every answer among ten blue links. More and more, they ask AI directly and get a single, synthesized answer.

That answer usually names only a few brands. A brand that isn't mentioned is effectively invisible to the user — like being stuck on Google's second page, only sharper.

What GEO measures and improves

A GEO effort measures first: how often your brand is mentioned in category questions, your share of voice versus rivals, and which sources AI draws from.

Then it improves: by working on brand/entity presence, content citability and technical access, it raises the odds AI mentions you.

The honest part: GEO is a young discipline and nobody can promise guaranteed rankings — model behavior shifts week to week. What can be promised is a process: measure, fix across three layers, re-measure monthly. We run this exact process on our own brand with the same metrics and report to clients with the same transparency; if you see a GEO pitch selling 'guaranteed first mention', ask for the measurement methodology.
