What is AEO, and how is it different from SEO and GEO

What AEO is

AEO, answer engine optimization, is the work of getting your page used as the source of a direct answer instead of appearing as one link among ten.

An answer engine is any search product that replies with an answer rather than a list. That includes AI Overviews at the top of Google, AI Mode, Perplexity, and ChatGPT when it searches the web.

If you already know what a featured snippet is, you already understand the shape of this. AEO is that same objective, applied to answers that are written rather than quoted, across several products instead of one.

AEO, SEO and GEO, told apart

Three words, three different prizes. People use them loosely and the distinctions are real.

What each of the three disciplines is trying to win.
Term	The prize	How you know you won
SEO	A high place in a list of links	Your position, and the clicks it brings
AEO	Being the source an answer is built from	Your page is cited under the answer
GEO	Your business named inside the answer	How often the name appears when buyers ask

The useful way to hold it: AEO is about your page being used. GEO is about your business being named. They often happen together and they are not the same event, which matters the moment you decide what to count.

How an answer engine picks its sources

It searches, opens a small handful of pages, and writes an answer out of the passages it found most usable. Often around five pages. Every other page on the subject is not consulted.

The technical name for this is RAG, and it is worth knowing one thing about it: the fetch happens live, at the moment somebody asks. That is called retrieval, and it is why publishing a clear page can change an answer within days.

What the engine is looking for inside those pages is a passage it can lift. Not a whole page. A passage. Anchoring the answer to real fetched text is called grounding, and it is why a page that states something plainly beats a better page that circles it.

What a liftable page looks like

A page wins answers when the answer is findable in it without reading the whole thing. Five properties do almost all of the work.

The answer is in the first paragraph. Before any persuasion, background or history. A page that warms up for four hundred words has nothing to lift.
One page answers one question. A page covering ten things is a weaker match for each of them than ten pages would be.
The heading is the question. Phrased the way a person would say it out loud, not the way your industry writes it internally.
Claims carry checkable facts. A number, a date, a named source. Specifics get quoted because they can be verified; adjectives cannot.
Sentences stand on their own. A sentence that needs the previous paragraph to make sense cannot be quoted in isolation, which is the only way it will ever be quoted.

A good test: take any single paragraph out of your page, show it to somebody with no context, and ask what question it answers. If they cannot say, an engine cannot either.

The questions themselves are not a guessing game. People Also Ask on any Google results page is a free list of the exact wording real people use.

Does structured data help? The field disagrees

Structured data is machine-readable facts placed in a page’s code, usually written in JSON-LD using the shared vocabulary at Schema.org. Whether it helps you get cited is the most contested question in this subject, so here are both positions.

The case for: it removes guesswork. A machine choosing between sources should favour the one that states plainly what it is. It is also cheap, standard, and helps ordinary search regardless.
The case against: the largest test found nothing. Ahrefs tracked 1,885 pages that added structured data between August 2025 and March 2026 against 4,000 comparable pages that did not. Citations moved down 4.6% in AI Overviews and up about 2% in AI Mode and ChatGPT, which is inside the noise.

One study with a control group is much better evidence than a thousand blog posts without one, and it is still one study. Our read: add structured data because it is cheap and it helps search, and stop treating it as the lever for AI visibility. If somebody sells it as that lever, ask them what they measured it against.

How to measure AEO without fooling yourself

Ask the questions your buyers ask, several times each, and count how often your page is used and your business is named.

Several times is the part everybody skips. Answer engines do not repeat themselves exactly, and that spread is called variance. Asking once and writing down the result produces a number that looks like a fact and is a coin flip. Asking repeatedly is called sampling, and it is the difference between a measurement and an anecdote.

Two things are worth counting separately. A citation means your page was read. Your mention rate means your business was named. Being cited without being named happens constantly, and it converts nobody.

Watch zero-click behaviour too. If impressions hold while clicks fall, you are winning the answer and losing the visit, which is a success in AEO terms and needs a different measure of value than traffic.

Is AEO a real discipline, or rebranded SEO?

Genuinely arguable, and you will meet both camps, often angrily.

It is just good SEO with a new name. Every practice on the list above was already best practice: answer early, write clearly, be readable, be specific. Nothing here requires a new budget line or a new vendor.
It is a different job because the scoreboard changed. Position no longer describes the outcome. You can rank first and be absent from the answer above your own listing, and no traditional measure will tell you that happened.

Both are right about something, and they are arguing about different halves. The work is largely the same work. The measurement is genuinely new, because nothing in Search Console tells you whether AI search named you. That gap is the only part we would spend money on.

Glossary

Every term used above, each defined without needing another definition to make sense of it.

AEO: AEO, or answer engine optimization, is the work of getting your page used as the source of a direct answer, such as the box at the top of a results page, rather than as one link among ten.
SEO: SEO, or search engine optimization, is the work of getting a page of your website to appear high in a list of search results.
GEO: GEO, or generative engine optimization, is the work of making it more likely that AI search names your business when someone asks it a question about what you sell.
Answer engine: An answer engine is any search product that responds with a direct answer instead of a list of links.
AI Overviews: AI Overviews are the AI-written answers Google places above its normal list of links.
AI Mode: AI Mode is Google's fully conversational search experience, where the whole result is an answer you can ask follow-up questions of.
Featured snippet: A featured snippet is the short answer Google lifts from a page and shows in a box at the top of the results.
Zero-click search: A zero-click search is one where the person gets what they needed without visiting any website.
Citation: A citation is a link or source name AI search shows next to its answer to indicate where a piece of information came from.
Retrieval: Retrieval is the step where AI search fetches live web pages in the middle of answering you, instead of relying only on what it already knows.
RAG: RAG, or retrieval-augmented generation, is the standard way AI search answers a question about the live web: search first, read the results, then write the answer using them.
Grounding: Grounding is tying an answer to real fetched sources rather than letting the model answer from memory.
Structured data: Structured data is information written into a page in a fixed format that states plainly what the page is: that this is a product, that this is its price, that this is the business selling it.
JSON-LD: JSON-LD is the format structured data is usually written in: a block of machine-readable facts placed in the page's code.
Schema.org: Schema.org is the shared vocabulary that structured data uses, defining what counts as a product, an organisation, an article and so on.
People Also Ask: People Also Ask is the expandable list of related questions Google shows inside its results.
Sampling: Sampling means asking the same question several times instead of once, because AI search does not give an identical answer every time.
Mention rate: Mention rate is the share of answers that named your business, out of all the times a question was asked.
Variance: Variance is how much a result moves around when you repeat the same test.
Control group: A control group is a comparable set you leave alone, so you can tell whether a change caused a result or everything moved anyway.
