What is Answer Engine Optimization (AEO)?
AEO is the practice of making your site easy for AI answer engines like ChatGPT, Gemini and Perplexity to read, understand and cite.

Answer Engine Optimization (AEO) is the practice of structuring a website so AI answer engines, ChatGPT, Gemini, Perplexity and Google's AI Overviews, can read it, understand it, and cite it when they answer a question. Where SEO optimizes for a ranked list of links, AEO optimizes to *be the answer*.
Why AEO exists
People increasingly ask an assistant instead of scrolling a results page. Gartner projects a 25% drop in traditional search-engine volume by 2026 as people turn to AI. When the answer comes back as a paragraph with two or three named recommendations, the only thing that matters is whether *you* are one of them.
What AEO actually optimizes for
- Crawlability: can an AI bot fetch the page at all? (robots.txt, no login wall, fast response.)
- Rendering: is the content in the raw HTML, or hidden behind JavaScript the crawler never runs? See does ChatGPT read JavaScript?
- Structured data: Schema.org markup that states plainly what the page is.
- Answer shape: a direct lead answer, question-style headings, and a real FAQ section.
- Trust: E-E-A-T signals an engine can verify: an author, a date, citations, an About page.
AEO, SEO and GEO
These overlap but aren't the same. SEO targets the classic ranked list; GEO (generative engine optimization) is the broader name for influencing generative AI output. AEO is the answer-focused core of both. We break down the differences in AEO vs SEO vs GEO.

Frequently asked questions
What does AEO stand for?
- AEO stands for Answer Engine Optimization, optimizing a website to be read and cited by AI answer engines like ChatGPT, Gemini and Perplexity rather than only ranking in a list of links.
Is AEO the same as SEO?
- No. SEO optimizes for a ranked list of links on a search results page. AEO optimizes to be the answer an AI engine gives directly. The technical foundations overlap, but the goal and the success metric differ.
How do I check if my site is AEO-ready?
- Run a tool that fetches your page as an AI crawler does, raw HTML, no JavaScript, and checks crawlability, structured data, answer shape and trust signals. CheckAIVisible's free checker scores all of these.
