AEO vs. GEO vs. SEO: what's the difference?

All three acronyms share a goal: getting your products in front of buyers. They aim at different surfaces. SEO optimizes for a ranked link a person clicks. AEO and GEO optimize for being named inside an AI-generated answer. This guide covers how they differ, where they overlap, and why a shop of any size wants both.

SEO ranks your link in the list. AEO and GEO are two names for the newer road: getting named in the answer itself. Keep the first, add the second, and you reach the shopper both ways.

In one line

Same goal, different surface

SEO gets you found. AEO gets you quoted.

SEO's currency is position: where your link ranks on a page of results. AEO's currency is citation: whether the assistant's answer names you, quotes your facts, and links your page. GEO ("generative engine optimization") is a near-synonym of AEO you'll see more in B2B. It's the same idea and the same work.

AEO and GEO are the same discipline under two names. Commerce tends to say AEO, and B2B tends to say GEO.
The good news

They overlap more than they compete

This part saves you work: SEO and AEO reward a lot of the same things. Clean, structured, trustworthy content helps you rank and helps you get quoted. Improve one thoughtfully and you usually lift the other.

The middle is where your effort pays off twice, once on each surface.
The takeaway

Layer them instead of picking one.

SEO is the foundation the answer layer sits on. Assistants read the web, so healthy SEO still feeds them. In 2026, keep your SEO in order, then add an answer layer on top.
