GEO: being found by ChatGPT and Perplexity, not just Google

Until yesterday, "being online" meant one thing: showing up on Google. Today that's no longer enough. Millions of people have stopped typing three keywords into the search bar and started asking full questions to ChatGPT, Perplexity, Gemini or Copilot. And the assistant doesn't return ten links: it returns one answer, citing a few sources. The question that matters for your business is simple: does that answer talk about you?

What GEO is

GEO — Generative Engine Optimization — is the set of techniques that make your site understandable and citable by generative engines, that is, AI assistants. Where traditional SEO aims to climb the link ranking, GEO aims at a different goal: being the source the AI chooses when it composes its answer.

It doesn't replace SEO: it extends it. A site well optimized for Google starts with an advantage, because AI assistants draw largely from the indexed web. But the criteria by which a language model decides "this sentence is the right answer" aren't identical to those of a classic search engine.

Why it concerns you now

Someone arriving from an AI assistant is often further along in the buying journey: they've already delegated the research, they trust the summary and they want to act. If you're the cited source, you reach the customer pre-qualified. If you're not there, the competitor cited in your place takes that trust — and you don't even notice, because in your analytics that traffic often doesn't show up the way you know it.

Google's first page was the battlefield. The AI's first answer is the new battlefield — with far fewer spots available.

How to do it, in practice

No magic, no tricks: GEO rewards clear, structured and reliable content. Here's what really matters.

1. Answer the real questions. Structure pages around real customer questions, with direct answers in the first lines. Models extract better the passages that answer on their own, without needing surrounding context.
2. Structured data (schema.org). Marking up products, FAQs, articles, reviews and company info with JSON-LD gives the model a readable skeleton: it understands what each thing is, not just which words are present.
3. Authority and evidence. Concrete numbers, sources, examples and a competent tone increase the chance of being cited. Vague claims get discarded in favor of verifiable ones.
4. Accessibility to AI crawlers. A robots.txt that explicitly allows GPTBot, ClaudeBot, PerplexityBot and Google-Extended, and an llms.txt file summarizing the site, tell assistants "I'm here, read me".
5. Clarity above all. Short sentences, one idea per paragraph, headings that really say what's underneath. What's easy to read for a person is easy to extract for a model.

How to measure it

GEO is harder to measure than SEO, but it's not invisible. You can ask assistants the typical questions of your industry and see whether — and how — you're cited. You can track AI crawler visits in your logs. And you can watch the growth of direct traffic and "I already knew who you were" requests: it's often the sign that an AI answer acted as your go-between.

The takeaway

SEO gets you found in the list. GEO makes you become the answer. The two work together: clear, structured content, marked-up data, real authority and open doors to AI crawlers. It's not a passing fad — it's how a growing share of people discover companies. Better to be there before your competitors.
