What is GEO?

Everything you need to know about Generative Engine Optimization, the new discipline for being visible when AI responds to your future customers.

GEO: simple definition

GEO stands for Generative Engine Optimization — optimization for generative engines (ChatGPT, Gemini, Claude, Perplexity, etc.).

Just as SEO optimizes your visibility in Google, GEO optimizes your visibility in AI responses. The goal: be cited as a reliable source and recommended as a relevant solution.

GEO

AI gathers sources

Generative engines consult dozens of sources — websites, listings, reviews, directories, videos — to build a complete and reliable response.

It actively recommends

When a user asks a question like « the best plumber in Lyon », AI doesn't just list — it cites a website and recommends a business.

Two key questions

  • Is your site cited as a source?
  • Is your business recommended?

Why it matters for your business

Search habits are changing. More and more consumers and professionals turn to AI first before making a decision.

What the research says

Academic studies have experimentally shown that conversational AI can significantly shift consumer preferences, without users realizing it. For your brand, this means that being absent from AI responses is not neutral — it's a battleground where your competitors win by default.
