AEO vs SEO: What's the Difference?
The short answer
SEO optimizes for ranked positions in a list of search links; AEO optimizes for being the source an AI answer cites. SEO success is a top-10 ranking and clicks. AEO success is being cited or mentioned in a synthesized answer. They share fundamentals but AEO adds crawler access, passage extractability, and entity trust.
What's the core difference?
SEO competes for a position in a ranked list a user scans and clicks. AEO competes to be one of a handful of sources an AI engine synthesizes into a single answer — often with no click at all.

Frequently asked questions
+Will AEO replace SEO?
Not soon. Traditional search still drives large volumes of traffic, and AI engines often rely on search results to ground answers. The practical stance is to keep SEO and add AEO, since they measure and optimize for different outcomes.
+Can good SEO make me visible in AI answers?
It helps but isn't sufficient. If AI crawlers are blocked or your content isn't cleanly extractable, you can rank well and still never be cited. AEO addresses those gaps directly.
+How do I measure AEO alongside SEO?
Use a rank tracker for SEO and an AI-answer tool like cited? for AEO. The latter reports whether AI engines cite, mention, or ignore you for your buyers' questions.
