Getting cited by ChatGPT, Gemini and Perplexity: GEO/AEO explained

The essentials in brief

A growing share of your prospects no longer type a query into Google to browse ten links: they ask a question to ChatGPT, Perplexity or Gemini, and read a synthesised answer that cites a few sources. If your company is not among those sources, you become invisible across a whole part of the search journey.

GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) describe the art of being understood and cited by generative engines. It is not a replacement for SEO, but an extension. This article explains what makes content "citable" by an AI, and why it is already a visibility issue in 2026.

What changes with generative engines

Classic search optimises for a ranking of links. GEO/AEO optimises to be kept in an answer. The difference is significant:

• A search engine displays ten results; the user chooses.
• A generative engine writes one answer and cites only a few sources.

The competition is no longer "appearing on the first page", but "being among the small number of sources the model judges reliable and clear". That rewards a different kind of content.

What makes content "citable" by an AI

Generative engines favour content that makes their job easier: extracting a reliable answer and synthesising it. Concretely, they favour:

• Clear, direct answers. A question asked, a crisp answer in the opening lines — not content that circles the subject.
• A readable structure. Explicit headings, short sections, lists, FAQs. Structure helps the model isolate the information.
• Verifiable, dated facts. Sourced figures, dates, precise definitions. The vague is not cited.
• Authority and consistency. A subject treated in depth, consistently across the whole site, inspires more trust than an isolated page.
• Sources. Citing your own sources reinforces the perceived reliability of the content.

You will notice these principles overlap with those of good content, full stop. GEO rewards clarity — it penalises filler.

GEO, AEO, SEO: do you have to choose?

No. These approaches reinforce one another:

• SEO makes you findable in classic search engines.
• AEO optimises your content to answer questions directly.
• GEO aims to be cited by generative engines.

Content that is clear, structured, factual and authoritative performs on all three. The mistake would be to treat GEO as a separate technique, disconnected from editorial quality.

A visibility issue — but also one of control

Being cited by an AI means letting a model speak about you on your behalf. Better, then, that it has clear, accurate and up-to-date information about you. A vague, dated or inconsistent site means a model that summarises you badly — or cites a more legible competitor.

Visibility in the age of AI is therefore prepared upstream, in the way your online presence is designed and structured. It is a full component of the digitalisation of your business.
