Definition
Answer Engine Optimization (AEO) is the practice of structuring your website content, brand positioning, and digital presence to maximize visibility and citation in AI-powered answer engines.
Unlike traditional SEO, which optimizes for ranking in search engine results pages (SERPs), AEO optimizes for being the answer that AI systems provide to user queries.
When a user asks ChatGPT "What's the best CRM for small business?" or asks Gemini "Who are the top consultants in [industry]?", AEO determines whether your brand is mentioned, how it is described, and whether it is recommended.
Key Concepts in AEO
First 50 Words Rule
LLMs weight the beginning of content heavily. Your homepage and key pages must include WHO you are, WHAT you do, WHERE you operate, and your PRICE in the first 50 words.
