What is Answer Engine Optimization (AEO)?

Answer Engine Optimization (AEO) is the practice of structuring your content so it can be returned as the direct answer to a question, whether by an AI answer engine like ChatGPT or Perplexity or by a search answer feature like a featured snippet. Where broad SEO optimizes a page to rank, AEO optimizes a specific passage to be lifted and served as the answer itself.

How AEO differs in emphasis

AEO grew out of optimizing for featured snippets and voice assistants, so it leans hard on one idea: answer the question directly, early, and completely. That means question-style headings, a concise answer in the first sentence or two, and self-contained passages a machine can extract without needing the rest of the page for context.

What AEO involves in practice

• Question-shaped structure: headings that match how people ask, with the answer immediately below.
• Self-contained answers: passages that still make sense when lifted out of the page.
• Structured data: FAQ, QAPage, and HowTo schema that label the answer for machines.
• Clarity and brevity: plain language and a clear lead, so the answer is easy to reuse.

AEO, GEO, and LLMO

Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), and Large Language Model Optimization (LLMO) describe the same goal from different angles, and the terms are largely interchangeable. AEO emphasizes the answer surface, GEO the generative engines, and LLMO the models underneath. We group all three under AI Answer Engine Optimization and measure the outcome as your AI Search Visibility Score.
