GEO: making your brand citable by AIs

A new discovery surface has emerged: generative engines such as ChatGPT, Gemini and Perplexity. They no longer return a list of links, but a synthesised answer — and the question for brands becomes: how do you get cited in that answer?

What is GEO?

GEO (Generative Engine Optimization) refers to all the practices that make content understandable, reliable and citable by artificial intelligences. Where SEO aims for a good ranking among Google’s links, GEO aims to become the source an AI draws on to formulate its answer.

How AIs choose their sources

Generative engines favour content that is clear, factual and well structured. They rely on passages that directly answer a question, on verifiable data, and on the authority of a domain. Vague, purely promotional or poorly structured content has little chance of being picked up.

• Structured data (JSON-LD) that explicitly describe your business, your pages and your FAQs.
• Answers in natural language, addressing one precise question per section.
• Verifiable facts rather than marketing superlatives.
• Consistency between your website, your listings and your external mentions.

GEO and SEO go hand in hand

GEO does not replace SEO: it extends it. The foundations are largely shared — a fast site, a clear architecture, quality content and structured data serve both at once. A brand that ranks well on Google starts with a head start when it comes to being cited by AIs.

At Lumineth, we build GEO in from the design stage: content structured for question-and-answer, systematic JSON-LD markup and an SEO strategy that covers both Google and generative engines. This is how a brand stays visible, whatever way its customers search.
