SEO, AEO and GEO: what actually changed about being found
Three acronyms, one underlying shift. What each means in practice for a small business, and which of them is worth your attention first.
The short answer
- What is the difference between SEO, AEO and GEO?
- SEO is being findable in a list of results. AEO is being the source an engine quotes when it answers a question directly. GEO is being described accurately by AI assistants that summarise rather than link. They share the same foundations — a crawlable site with clear structure — but differ in what the destination looks like.
- Should a small business worry about AI search yet?
- Worry, no. Prepare, yes — and the preparation is almost entirely work that helps ordinary search anyway. Clear structured data, consistent business information everywhere, and content written as direct answers. There is no separate AI budget to find.
Three acronyms have arrived in roughly four years, and most explanations of them are written to make the difference sound larger than it is.
The underlying shift is simpler than the vocabulary suggests: fewer people are clicking through to find an answer, because the answer increasingly arrives before the click.
SEO — being in the list
Search engine optimisation is the familiar one. Someone searches, gets ten results, and you want to be among them.
This still matters and has not gone away. But the list is lower on the page than it was, and a growing share of searches end without anyone visiting a website at all.
AEO — being the answer
Answer engine optimisation is about being the source that gets quoted rather than the link that gets listed — featured snippets, “people also ask”, voice assistants.
In practice this is less mysterious than it sounds. It means:
- Writing headings as the questions people actually ask, not as keyword fragments
- Putting a direct answer immediately underneath, in two or three sentences, before the explanation
- Using real tables and real lists rather than images of them
- Marking up genuine FAQs with FAQ structured data
That is most of it. An engine can only quote a clean answer if you wrote one.
GEO — being described correctly
Generative engine optimisation is the newest and the least settled. When someone asks an AI assistant for a recommendation, it does not return a list — it describes a handful of options in prose.
You cannot optimise your way into that the way you can optimise for a ranking. What you can do is make your business unambiguous:
- Structured data that states plainly what you are, where you operate, and what you offer
- The same business name, address and phone number everywhere, with no variations
- Factual, dated content that is safe to cite
- A consistent description across your site, your Google Business Profile, and every directory
Assistants assemble a picture from whatever they can find. If your details differ across five places, the picture is blurry, and a blurry picture does not get recommended.
What they share
All three sit on the same foundation:
| Foundation | Helps |
|---|---|
| Site is crawlable and fast | SEO, AEO, GEO |
| Clear heading structure | SEO, AEO |
| Structured data | AEO, GEO |
| Consistent business information | SEO, GEO |
| Content that answers real questions | all three |
This is the useful part. There is no separate AI budget to find. Doing the visibility work properly serves all three, because they all depend on a machine being able to understand what you do.
Where to start
In order:
- Fix the technical foundation. If a search engine cannot crawl it or it takes six seconds to load, nothing else matters.
- Claim and complete the Google Business Profile. For a local trade this is still the highest-return hour available, and it feeds AI answers too.
- Make your business information identical everywhere. Name, address, phone, description. Tedious and genuinely effective.
- Write the answers you already give on the phone. Question as the heading, answer underneath. That one habit serves SEO, AEO and GEO simultaneously.
- Then think about content volume, once the first four are done.
What nobody can promise you
Not a position, not a traffic number, not that an assistant will mention you. Anyone offering guaranteed AI visibility is describing something they cannot control.
What is controllable is whether your business is legible to a machine. That part is entirely within reach, and most small businesses have not done it.
