Search is changing. When someone types a question into ChatGPT, Perplexity, or Google's AI Overviews, they don't get a list of ten blue links, they get a direct answer. That answer comes from somewhere. The question is whether it comes from your site.
What is AEO?
Answer Engine Optimization (AEO) is the practice of structuring your website content so that AI-powered tools can extract it and surface it as a direct response to user queries. Where SEO optimizes for search engine rankings, AEO optimizes for AI citation and direct answer inclusion.
The distinction matters because the two goals are increasingly different. A page can rank #1 on Google and never appear in a ChatGPT response. A page with clear, concise, well-structured content might not rank highly but gets cited repeatedly by AI engines. AEO closes that gap.
Why AEO matters now
AI-generated answers are becoming the first response to billions of queries. ChatGPT has over 100 million weekly active users. Perplexity is growing rapidly as a research tool. Google's AI Overviews now appear above organic results for a significant percentage of searches.
If your content isn't structured for AI extraction, you're invisible in an increasingly large slice of the search landscape, even if your traditional SEO is strong.
The key AEO signals
llms.txt: A plain-text file in your root directory that tells AI crawlers what your site does and how to use your content. Similar to robots.txt but designed for large language models.
FAQ schema: Structured data that marks up question-and-answer content explicitly. AI engines use this to extract direct answers.
Concise definition paragraphs: Content written in the 40-60 word "snippet format" that directly answers a specific question. AI extractors favor this format heavily over long-form prose.
Entity clarity: Clear signals about who you are, what you do, and what category of business you are. Organization schema, About pages, and consistent brand mentions all contribute.
Clear heading structure: H2/H3 headings phrased as questions, followed immediately by answers. This maps directly to how AI engines parse content for citation.
