GEO, AEO and agent optimization: what's actually different
Generative engine optimization is about getting cited in AI answers, while agent optimization is about getting chosen and transacted with. The two overlap, but the differences between them decide what work you should do.
There’s a growing alphabet of terms for “being visible to AI”: SEO, GEO (generative engine optimization), AEO (answer engine optimization), and now a handful of names for optimizing for agents. Some of the difference between them is marketing, but some of it is real and changes what work you should do. This is how we draw the lines.
SEO
Search engine optimization is about ranking on a results page that a human reads. The levers are content, links, technical health and, for local businesses, the Google Business Profile. The human does the choosing.
GEO and AEO
Generative engine optimization and answer engine optimization are close to the same thing. The goal is to be the source that an AI answer cites or draws from when a person asks a question. A question like “What’s a fair price for a roof replacement in Denver” gets an answer, and you want your page to be where that answer came from.
The levers overlap with SEO (authority, clear content, structured data) but tilt toward being quotable, which means direct answers near the top of the page, statistics, clear definitions, FAQ markup, and fresh dateModified timestamps. The human still reads the answer and decides.
Agent optimization
An agent does something different from an answer engine, because it’s completing a task for a person. A request like “Book me a roof inspection this week” has no use for a citation. What it needs is a business that the agent can identify, evaluate, and book with.
That changes the levers in three ways.
The first is that an agent needs facts more than it needs prose. An agent evaluating candidates cares about whether your price, availability, service area and policy are stated in a form it can act on. A well-written 2,000-word guide to roof inspections helps GEO, while a Service entry with a price and a booking link helps the agent.
The second is that transactability becomes the deciding factor. GEO doesn’t care whether someone can buy from you without a phone call. An agent does, because its owner asked for an outcome, and most of the time a business that’s easy to book beats a business with better content.
The third is that a record of past interactions starts to matter. Search and answer engines weigh reviews written by people. Agents weigh those too, and they will increasingly weigh their own experience and other agents’ reports about whether a booking went through or whether the quoted price held. GEO has no equivalent for that kind of reputation, and we’re building the shared record for it.
Where they overlap
They overlap a lot. Good technical SEO (crawlable, fast, no broken pages), structured data and consistent listings help with all of it, and clear answers to common questions help both GEO and agents. If you already have an SEO or GEO program running, you’re not starting from zero.
It’s a mistake, though, to assume that the GEO program covers the agent case. A GEO program usually doesn’t check whether checkout works without a human, whether your booking system exposes availability, whether you publish a UCP profile, or what an agent would conclude from your review history. Those are the gaps that decide whether you get chosen.
A simple way to think about it
Ask three questions about how a customer gets to you:
- Can a person find and read about us? That’s SEO.
- Can an AI answer cite us when a person asks a question? That’s GEO or AEO.
- Can an AI agent choose us and complete the transaction without the person doing anything? That’s agent optimization.
Most businesses have worked on the first, and some have started on the second. Almost nobody has checked the third, which is the one where the platforms moved fastest in the last twelve months.
What to do about it
If you have an agency, ask them the third question directly and see what they say. If their answer is about content, they’re describing GEO.
To check it yourself, the agent-readiness checklist walks through the twelve things we look at.
If you’d prefer that we check it, request a free assessment, and we’ll tell you where you stand on the third question specifically.

The assessment is free. A person checks where you stand in search and AI answers, runs the four agent checks (Find, Understand, Transact, Trust) and tries to book or buy, then emails you a one-page report with the three fixes we think matter most.
