Answer engine optimization (AEO) is the practice of structuring and writing content so AI-driven answer engines — Google's AI Overviews, ChatGPT, Perplexity, and similar tools — can easily understand it, choose it, and cite it when generating direct answers to users' questions.
Traditional SEO aims to rank a page so a person clicks through. AEO aims for something subtler: to be the source an AI model quotes when it answers on your behalf, often without a click at all. That shifts the goal from "own position one" to "be the fact the machine trusts." The two reinforce each other — strong conventional rankings make you a likelier citation — but AEO adds a layer of clarity and structure aimed at systems that read, summarize, and attribute.
Answer engines favour content that states a clear answer up front and proves it below. A SaaS help page rewritten from a rambling intro into a one-sentence lead answer — "Our free plan includes 3 users and 5 GB of storage" — followed by FAQ schema and supporting detail started appearing verbatim in ChatGPT and AI Overview responses within a month.

AEO sits alongside generative engine optimization and directly targets features like AI Overviews. It's a core part of our answer engine optimization services.
