# What is Generative Engine Optimization (GEO)?

For twenty years, being found online meant ranking on Google. That assumption is breaking. A growing share of buyers no longer search a list of links — they ask an AI assistant a question and act on the single answer it returns.

**Generative Engine Optimization (GEO)** is the practice of making sure your brand is the answer. Where SEO optimizes for a ranked page of links, GEO optimizes for being *named, quoted, and recommended* inside an AI-generated response.

## Why GEO is different from SEO

Search engines return ten blue links and let the user choose. Generative engines return one synthesized answer and cite a handful of sources. That changes the game in three ways:

- **There is no page two.** If you are not in the answer, you are invisible — there is no scrolling to find you.
- **Citations are the new clicks.** Being named as a source in an AI answer is the unit of visibility, the way a top organic ranking used to be.
- **Machines read differently than people.** An assistant extracts atomic, verifiable claims. Marketing prose that reads beautifully to a human is often unusable to a model.

## What generative engines actually reward

Across ChatGPT, Claude, Gemini, and Perplexity, the same signals come up again and again:

1. **Structured data** — valid [schema.org](https://schema.org) markup so a model can parse who you are and what you sell without guessing.
2. **A grounded entity** — a consistent identity ([Wikidata](https://www.wikidata.org/), sameAs links, one canonical description) so models agree you exist and what you do.
3. **Citable claims** — short, standalone, evidence-backed statements a model can lift into an answer.
4. **Machine access** — fast, render-free HTML that AI crawlers are allowed to read.

## Where to start

You cannot improve what you cannot see. The first step is to measure how legible your site already is to AI — then close the highest-impact gaps. That is exactly what the [Legible Readiness Index](/platform) is for.

GEO is early. The brands that get structured, grounded, and citable now will own the answer while competitors are still optimizing for a page of links that fewer people read.
