SEO, GEO, AEO: What Does Each One Do, and Where Do They Clash?

SEO ranks you in the list of blue links. AEO makes you the answer shown on the page. GEO makes you the source an AI engine cites. Three acronyms, three invoices, and one shared foundation underneath all of them.

Over the past year a whole industry has appeared selling SEO, GEO and AEO as three different services at three different prices. Let us take them one at a time, then get to the part nobody mentions: where the work for one damages another.

What each one does, in a sentence

SEO ranks you in the list of blue links. Somebody searches, sees ten results, clicks one.

AEO makes you the answer. The box at the top, the voice answer on a phone, the fragment Google lifts out of your page and displays as it is.

GEO makes you the source. Somebody asks ChatGPT, Gemini or Perplexity which brand design studio to choose, and your name appears in the answer with a link.

How different are they really

Less than it sounds. In the industry, the distinction between AEO and GEO is described as more a matter of branding than of strategy: both mean structuring your content so a machine can extract and display it, rather than so a human who clicked can read it.

The real difference that survives, once you take the marketing out, is length. AEO wants the short, clean answer, ready to be lifted. GEO wants factual density, so the model has something to cite on a complicated question. That is it.

The foundation, though, is identical for all three, and it has been the same for ten years: a site that loads fast, that engines can read without struggling, with pages built around a question somebody actually asks. Anyone invoicing you for three separate services is selling you the same foundation three times.

Why this is being sold now

Because a number appeared that justifies it. In the United States, 68% of Google searches in the first part of 2026 ended with no click at all, up from 60% two years earlier. And when an AI Overview appears on the results page, the click-through rate on the first result drops by 58%, according to Ahrefs data from December 2025.

Those numbers are American. Other markets move at their own pace, in the same direction, and position one no longer means what it used to.

The four places where they work against each other

This is the part worth reading.

1. The complete answer costs you the click. Put the whole answer, plainly, in the first paragraph and you have done exactly what AEO asks for. Google lifts it, displays it, and the reader leaves satisfied without ever visiting you. You won the visibility and lost the visit. The fix is not to hide the answer, it is to keep something on the page that does not fit in three lines: a calculation, numbers from a real case, a comparison, an example with a name on it.

2. Chopping the text into questions thins the page. Plenty of people worked out that AI engines prefer paragraphs that stand on their own, so they broke their pages into twenty short questions. The result is a page that no longer says anything in depth about anything, and that loses the ranking it had. Questions go underneath the content, not instead of it.

3. Authority is not bought with schema. Structured markup tells a machine what is on the page. It does not tell it you are worth trusting. GEO runs on sources the model has seen cited elsewhere, and that comes from verifiable things you wrote and from real mentions, not from one more JSON file. Schema on an empty page leaves you with an empty page, correctly described.

4. Hours spent on acronyms do not fix a slow site. The most common reason a site appears neither on Google nor in AI answers is that it loads in eight seconds and delivers its text through JavaScript. No GEO strategy gets past that. If you have to choose where next month goes, it goes into speed and structure, not into acronyms.

What to do, in order

The foundation first, because it serves all three at once: speed, clean structure, pages the engine can read without JavaScript.

Then the shape of the page: the short answer at the top so it can be lifted, and underneath, the part that earns a click. Write paragraphs that make sense pulled out of context, because that is how they get pulled.

Then the facts. Numbers, dates, names, sources. A paragraph that opens with “this means that” cannot be cited by anyone, because it does not stand on its own.

Then measure: which queries bring you impressions in Search Console, and what ChatGPT says about your brand when you ask it from a window where you are not logged in.

Short version

SEO, GEO and AEO are not three strategies. They are three shapes in which one thing done well brings you clients: a fast site, pages that answer real questions, and facts somebody can check. The difference between the brands that turn up everywhere and the ones that turn up nowhere is not the acronym they bought, it is how concretely they wrote down what they do.

If you want to see where you stand now, an online presence audit shows what is holding you back before you pay for any optimisation. And if you want the engine-by-engine mechanics, they are in how AI engines decide which brands to recommend.

FAQ

Do UK businesses need all three? Mostly the same work covers all three: a fast site, clear pages and consistent facts. Paying three UK suppliers for it is rarely needed.

What is the difference between SEO, GEO and AEO? SEO ranks you in the list of links. AEO makes you the answer shown directly, in a box or read out by voice. GEO makes you the source ChatGPT, Gemini or Perplexity cites in their answer. In practice AEO and GEO overlap almost completely, and the difference between them has more to do with how they are sold than with what you have to do.

Do I have to pay separately for GEO and AEO? No. The same work covers most of all three: a fast site, clean structure, pages that answer a real question, facts with numbers and a source. Anyone invoicing you for three separate services is selling you the foundation three times.

If I answer the question fully on the page, do I lose the click? Yes, sometimes you do, and that is the real tension between AEO and SEO. The page has to give the short answer at the top so it can be lifted, and keep something below that does not fit in a paragraph: numbers from your own case, examples, a calculation, a comparison. The gain is that you appear in the answer and in the list of links.

Does an llms.txt file help me show up in ChatGPT? There is no evidence so far that AI engines use it to decide who they cite. It costs ten minutes, so having one does no harm, but it is not a service worth paying for and it replaces none of the structure and content work.

Do people actually search for the words GEO and AEO? Barely. The jargon is not what gets typed. The question gets asked in plain language instead: how do I get ChatGPT to recommend me, why is my site not showing up on Google. Build the pages around those, not around the acronyms.
