Definition

GEO — Generative Engine Optimization — is the practice of optimizing content and brand signals to improve visibility and citation in AI-generated responses from systems like ChatGPT, Perplexity, Google AI Overviews, and other generative search engines. GEO extends traditional SEO principles to the specific requirements of generative AI retrieval and synthesis. GEO is one of the primary frameworks for AI search optimization alongside AEO and LLMO. It addresses the specific challenge of earning citations in AI-synthesized prose answers rather than ranked link lists. GEO optimizations focus on content extractability, entity clarity, factual density, and semantic authority — the characteristics that make content useful to AI systems that are generating comprehensive answers rather than returning lists of sources. GEO and SEO are complementary: strong SEO provides the foundation, and GEO-specific optimizations extend it into the generative layer.
