Generative Engine Optimization (GEO) is the strategic practice of optimizing brands, content, and websites for AI-driven search engines and Large Language Models (LLMs) like ChatGPT, Gemini, and Claude. Unlike traditional SEO, GEO prioritizes entity recognition, semantic clarity, and the ability to be cited or surfaced in AI-generated overviews.
