What is AEO, and why it matters now
AI engines answer questions directly instead of sending clicks. Here is what AEO is, how it differs from SEO, and how to start optimizing for it.
Search is changing. People used to type a query, scan ten blue links, and click. Now they ask ChatGPT, Perplexity, or Google AI Overviews and get a written answer. That answer is often built from a handful of sources, and your site is either one of them or it is invisible.
AEO, or AI Engine Optimization, is the practice of making your content easy for these AI systems to find, quote, and trust. It sits alongside classic SEO, not in place of it.
AEO vs SEO
SEO optimizes for ranking in a list of links. AEO optimizes for being the source an AI cites in its answer. The overlap is large, good technical health and clear content help both, but the emphasis differs.
- SEO rewards depth, backlinks, and keyword relevance.
- AEO rewards clear structure, direct answers, and signals of trust.
- A page can rank well and still never get quoted by an AI engine.
The four pillars
We measure AEO across four pillars. Each one maps to a question an AI system is implicitly asking about your page.
Findable
Can AI crawlers reach and index the page? This covers robots.txt access for AI user agents, a clean sitemap, and indexability signals.
Quotable
Is there a concise, self-contained answer the model can lift? FAQ blocks, definitions, and short summary paragraphs are easy to quote.
Understandable
Does the structure make meaning obvious? A single H1, a logical heading hierarchy, and schema.org markup all help.
Trustworthy
Are there signals the content is credible? Author bylines, citations, a contact page, and organization schema all build trust.
Where to start today
You do not need to rebuild your site. Start with the cheapest, highest-impact moves.
- Add a short summary paragraph near the top of important pages.
- Add FAQ schema to pages that answer common questions.
- Make sure your robots.txt does not block AI crawlers you want to reach.
- Add author and organization schema so engines know who is behind the content.
The sites that win AI search are not the loudest. They are the clearest.
