What Is Generative Engine Optimization (GEO)?

Generative Engine Optimization (GEO) is the emerging discipline of optimising websites and content to achieve visibility in AI-generated search responses. Just as SEO helps content rank in Google's blue-link results, GEO helps content get cited in ChatGPT answers, Gemini AI Overviews, Copilot responses, and Claude outputs.

The core difference from traditional SEO: AI engines don't just rank your page — they decide whether to cite you at all. That decision is influenced by entity recognition, structured data quality, content factual density, source authority, and the ability of the AI to extract clean, quotable information from your content. GEO addresses all of these factors with a systematic, measurable approach.

This hub contains the most comprehensive free resource on GEO available — covering all four major AI engines with specific ranking factor breakdowns, citation strategies, and tools to measure your progress.
