What is Answer Engine?
An answer engine is a search system that returns a single synthesized answer instead of a list of links — for example Perplexity, ChatGPT search, or Google AI Overviews.
An answer engine retrieves information from multiple sources and synthesizes a direct answer, often with citations, rather than returning a ranked list of links. Answer engines are the surface GEO optimizes for. Answer Engine Optimization (AEO) is frequently used as a synonym for GEO, with a slight emphasis on the retrieval-and-cite behavior of engines like Perplexity.
