Short definition
GEO (Generative Engine Optimisation) is the discipline of engineering content, structured data and corroborating signals so generative AI engines reliably cite the brand in the answers they generate for their users.
What GEO optimises for
Unlike SEO, which optimises for position on a search results page, GEO optimises for two outcomes simultaneously:
- Inclusion: being named in the AI's generated answer.
- Attribution: being linked to as a cited source.
Generative engines select sources using a different mechanism to traditional rank: entity clarity, structured data, freshness, and the depth of independent third-party corroboration.
Core GEO techniques
- Entity definition: structured, machine-legible "who, what, for whom" across schema and core pages.
- Answer-shaped content: replacing keyword-led pages with direct, citable answers to buyer questions.
- Corroboration paths: building independent third-party signal in press, professional bodies and datasets.
- Coherence audit: removing contradictory signal across the brand's own surfaces.
GEO inside the AVO discipline
GEO is the citation-and-inclusion subset of the wider AVO (AI Visibility Optimisation) discipline. AVO additionally addresses the entity, coherence and authority work that makes GEO possible at all.
What is GEO FAQs.
What does GEO stand for?
GEO stands for Generative Engine Optimisation. It is the practice of being cited by generative AI engines such as ChatGPT, Gemini and Perplexity.
Is GEO different from AEO?
GEO emphasises citation inside generative LLM answers. AEO emphasises direct-answer surfaces such as featured snippets and AI Overviews. They overlap and most practitioners run both together inside an AVO programme.
Is GEO replacing SEO?
Not replacing - extending. SEO and GEO target overlapping signals but different surfaces. Most brands now need both running in parallel.
How quickly does GEO produce results?
First measurable AI citation typically within 14 days; meaningful inclusion-rate lift across the four major engines within 60 days.
