A search tool that responds with a direct answer rather than a list of links, such as ChatGPT, Perplexity or Google's AI Overviews.
An answer engine is any system that responds to a question with a written answer instead of, or before, a list of links. Examples include ChatGPT, Perplexity, Gemini, Google's AI Overviews and AI Mode, and voice assistants.
Answer engines change what visibility means. When a buyer asks for the best provider in a category, the answer may name only a handful of businesses, so being one of them matters more than ranking somewhere on a page of results.
Most answer engines still depend on web search behind the scenes, which is why answer engine optimization starts with the same foundation as SEO: pages that can be crawled, indexed and trusted.
