Full definition
Classic search engines emphasize ranked documents. Answer engines—whether standalone products like Perplexity or features inside search and chat—aim to resolve the query in the interface. They may retrieve, rank, and summarize sources, sometimes with live browsing.
Optimizing for answer engines means writing extractable, accurate, well-structured content and ensuring crawlers that feed those products can access it. See AEO and Retrieval-Augmented Generation (RAG).
