What Is GEO? The Complete Guide to Generative Engine Optimisation

GEO is the practice of engineering your brand so AI engines like ChatGPT, Gemini & Perplexity cite you. Here's how it works in 2025.

Contents

    Generative Engine Optimisation (GEO) is the emerging discipline of engineering your brand, content, and digital presence so that large language models (LLMs), ChatGPT, Gemini, Perplexity, Claude, retrieve and cite your brand when users ask relevant questions.

    Traditional SEO optimises for Google's ranking algorithm. GEO optimises for LLM retrieval and citation mechanisms. Both are necessary. Neither is sufficient alone in 2025.

    Effective GEO requires a systematic approach across seven layers: entity registration, structured data, /llms.txt, citation architecture, topical authority, brand signal normalisation, and answer-engine optimisation.
