Search systems powered by large language models (LLMs) that generate answers or summaries instead of returning a ranked list of links. Examples include ChatGPT Search, Google AI Overviews (in Google Search), Perplexity, Microsoft Copilot, and Claude search. AI search prioritizes relevance and comprehensiveness over traditional ranking signals, requiring a different optimization approach than classic SEO. Zero-click search is more common in AI systems — users get their answer without visiting your site. See AI Search Explained and how AI search differs from Google Search.
