What isGenerative EngineOptimization?
The definitive guide to understanding how AI models like ChatGPT and Gemini answer questions — and how to ensure your brand is the one they recommend.
01 — The definition
GEO, defined.
Generative Engine Optimization (GEO) is the process of optimizing digital content and product data to be discovered, understood, and cited by AI-powered answer engines and Large Language Models (LLMs) such as ChatGPT, Google Gemini, Perplexity, and Claude. Unlike traditional SEO, which aims to rank blue links on a search results page, GEO specifically aims to secure direct recommendations and citations within conversational AI responses.
02 — The shift
GEO vs. SEO: what changed.

03 — The metrics
Three pillars of measurement.
01Pillar
Share of Model (SoM)
What percentage of the time does the AI recommend your brand compared to your competitors when asked a relevant, high-intent question?
02Pillar
Citation Frequency
How often is your brand explicitly linked as a foundational source for an AI's generated response?
03Pillar
Sentiment Entity Mapping
Does the AI associate your brand with positive attributes? Is it aware of your specific product features?
04 — The method
How to actually optimize.
AI models like ChatGPT do not "read" your website the same way a consumer does. They look for specific patterns, structured data, and high-consensus information through a process called Retrieval-Augmented Generation (RAG).
To succeed in GEO, your content must be "Definition-First". You must clearly and concisely state facts, define terms, and structure comparisons so that an AI slicing your page into small chunks can easily extract the perfect sentence to answer the user's prompt.
