AI Search & GEO: The Complete Guide

AI Search & GEO covers how large language models and AI-powered search surfaces choose, quote, and attribute the sources behind their answers. It spans Generative Engine Optimization, AI Overviews, grounding, citation share, and the technical files that control what AI crawlers read. The goal is not to rank a blue link but to be the source an AI answer cites.
