**TL;DR.** GEO (Generative Engine Optimization) is the set of techniques that make content citable by generative AIs such as ChatGPT, Perplexity, Gemini, Grok or Google AI Overviews. The goal: become the source the AI cites in its answer, not just a link buried in a results list.

## The definition, in one sentence

**GEO** stands for *Generative Engine Optimization*. It's the set of techniques that make an AI (ChatGPT, Perplexity, Gemini, Claude, Grok, or Google's AI summary) understand your content, trust it, and **cite it in its answer**.

> **A simple picture**
> SEO is being well placed in the directory. GEO is being the name the advisor recommends directly when someone asks. Today, that advisor is an AI.

## What is it actually for?

More and more people no longer search on Google: they ask an AI directly. "Which employment lawyer in Lyon?", "What invoicing software fits a small business?", "Who can rebuild my website?". The AI answers with a handful of names. GEO is what gets you into that shortlist instead of staying invisible in the answer.

## GEO vs. SEO: what's the difference?

- **SEO** → goal: show up in Google's list of blue links, to earn a click.
- **GEO** → goal: be cited inside the answer the AI writes, with or without a click.
- **What they share**: both reward content that's clear, structured, trustworthy and technically clean. GEO doesn't replace SEO, it extends it.

## How do you actually do GEO?

In short: make your site readable by AI crawlers (robots.txt, structured data, llms.txt), write pages that answer the real questions your market is asking, and build authority through mentions on third-party sources.

## Frequently asked questions

### Are GEO and AEO the same thing?

Very close. AEO (Answer Engine Optimization) focuses on providing THE answer to a question. GEO is a slightly broader term covering all optimization for generative engines. In practice, the two are worked on together.

### Is GEO only for large companies?

No, quite the opposite. It's still a lightly contested field: a well-structured freelancer or small business can become the reference answer in its niche before the big players catch up.
