What is GEO (Generative Engine Optimization)?

Also called: Generative Engine Optimization, LLMO, AI search optimization

GEO means preparing content so that AI search systems such as ChatGPT search, Perplexity or Google's AI Overviews can find it, understand it correctly and cite it as a source.

Simplified, schematic illustration.

Example

A bakery states clearly on its website which breads are gluten-free and lists the ingredients. When someone asks an AI search about it, the answer can link to that page as a source.

For pros

The term was coined by a research team around Pranjal Aggarwal (IIT Delhi, Princeton) in a paper at the KDD conference. In their tests, citing sources, adding quotations and adding backed-up figures made a page more visible in AI answers; keyword stuffing barely helped. GEO builds on SEO: according to Google, AI Overviews rely on the same fundamentals as regular search, and no special files or markup are needed. AEO and LLMO mean much the same and are often used interchangeably. There is no guarantee of being cited.
