AI Search
AI Search refers to search and discovery systems powered by large language models that generate synthesized answers from multiple sources rather than rank-ordering links in a traditional search results page.
Definition
AI Search systems include Google AI Overviews, ChatGPT, Perplexity, Microsoft Copilot, and similar platforms that use LLMs to understand queries and generate answers by retrieving and synthesizing information from indexed sources. Unlike traditional search which returns ranked links, AI Search returns generated text incorporating citations, links, and synthesis of multiple perspectives. The retrieval process differs from keyword matching, instead using semantic understanding and relevance scoring across a corpus of indexed content.
AI Search platforms vary in their approach to source selection and citation display. Some show explicit citations alongside each claim, others link to full source articles, and some display minimal attribution. Platforms also differ in their training data currency, retrieval methods, and commercial arrangements with publishers. Practitioners distinguish AI Search from traditional search and conversational search by its core focus on synthesis rather than ranking.
Why it matters for AI visibility
AI Search represents a fundamental shift in how users discover information online. Rather than scanning link results and clicking to sources, users receive generated answers that aggregate multiple sources into coherent responses. Brands must adapt visibility strategies from traditional search ranking to AI citation, as the discovery path fundamentally changes where users find information and which sources influence their decision-making.
