AEO vs SEO for agency clients: how to explain the difference

Clients use three new terms and expect an agency to know them. The short version is that they overlap a lot, and the agency's job is to explain where they differ. Our GEO vs AEO vs SEO guide covers the terms generally, and this one is written for the agency conversation.

Agencies that sell both can have the AEO side delivered with our white-label AEO and GEO.

The difference in one table

What stays the same

Google says that AI features draw on the same pages and signals as its other search features and that normal SEO best practice still applies. OpenAI documents a crawler for search features, which reads pages in much the same way. A fast, clear, crawlable page with accurate facts helps with both.

What changes in the agency conversation

• Questions replace keywords as the working list.
• Reports show a share across runs, because answers vary.
• Wrong facts in an answer become a task, which is rare in classic SEO.
• Ads in AI tools are a separate paid channel and not a result of the organic work.

How to sell both without overselling

Position AEO as an extension of the SEO program, with its own question list and its own report. Say plainly that no one can guarantee a mention. If a client has no SEO program yet, start there, since the same page work serves both. The AI Overview citations guide shows what that looks like for a service business.

A worked example: explaining it to a client in three minutes

Imagine a client who runs a veterinary practice and has just read an article about AI search. This is a script that works.

1. One sentence. "SEO is how you show up when people search. AEO is how you show up when people ask a chatbot."
2. One example from their own business. "If someone searches for a vet near them, Google shows a list. If they ask ChatGPT, it writes one answer and may name one or two practices."
3. One table. Show the table above. Keep the verdict column and point at the last row, because it sets expectations.
4. One promise you can keep. "We will check a fixed list of questions every month and show you how often you are named, and what we changed."
5. One next step. Agree the question list. If the client cannot write ten questions, that is the first piece of work.

How to decide where a client starts

Check three things in order. First, can the site be crawled and does it load fast? If not, fix that, because it helps both channels. Second, does each service have a page that answers the question in its first lines? Third, are the business facts the same on the site and the listings? Only after that does it make sense to build a question list and start measuring answers. A client with no SEO foundation does not need a separate AEO project yet, and saying so builds trust.

The effort involved

For a client who already has an SEO program, adding AEO is a few extra steps: the question list, a crawler check and a monthly ask. Plan about a day of setup, then a few hours a month. For a client with no program, the page work comes first and sets the schedule, so quote that separately.

What clients ask next

Is SEO dead?

No. Google says AI features use the same pages and signals as its other search features, and OpenAI documents a crawler that reads pages in a similar way. The page work still matters.

Which one should we do first?

SEO foundations first, since they serve both. Add the question list as soon as the basics are sound.

Is GEO a different thing again?

The terms overlap and people use them loosely. In practice the work is the same set of page, access and evidence tasks, with a monthly ask to check the result.

Can you guarantee a mention?

No, and neither can anyone else. We report how often you are named across repeated runs and what we changed.

Where each one earns its keep

SEO is the better fit when customers compare options and click through to read more, such as a buyer researching a contractor, a software tool or a legal service. AEO matters more when the customer wants a quick recommendation and may never open a results page. Most businesses have both kinds of customer, so the real question is how much of each you need to cover.

• Customers who browse and compare. Strong pages, links and reviews, which is the SEO work you already do.
• Customers who ask for one answer. Clear first lines, matching facts and a question list to check.
• Both at once. A page that answers the question quickly and then gives detail to anyone who scrolls.

SEO is the shop window. AEO is whether the person giving directions mentions your street. You want both.

A simple rule for the proposal

Put the shared work in one line item and the AEO extras in another. The client then sees what they are already paying for and what is new, and you avoid the sense that you are renaming the same job. Say clearly that neither one comes with a promised outcome.

Mistakes agencies make when they pitch AEO

• Selling it as a replacement for SEO, which the client will notice is not true when the site loses its search traffic.
• Showing one impressive screenshot and treating it as proof.
• Quoting a target number of mentions, since nobody controls that number.
• Skipping the baseline, so there is nothing to compare against in month three.

A short script for the sales call

"We will keep doing the search work that brings in visitors today. On top of that, we will write ten questions your customers ask, check what the assistants say about you, and fix what we can. Every month you will see the same questions asked again, and what we changed. We cannot promise a mention, and nobody honest can, but you will always see where you stand." Say it in your own words, and let the client interrupt with questions, since the follow-ups tell you what they are really worried about.

Mistakes to avoid

• Selling AEO as a replacement for SEO.
• Using the terms interchangeably in a proposal.
• Reporting AEO with ranking language.
• Ignoring crawler access because the pages already rank.

Three acronyms for one shop front. The shop does not mind what you call the sign, as long as it is on.

Where to go from here

Agencies that want both delivered can use our white label SEO and white-label AEO and GEO services together, under the agency's name.
