What is AEO?

AEO, or Answer Engine Optimisation, involves writing and structuring content in such a way that an AI chatbot or search engine can extract a ready-made answer from it and direct users to your website as a source. What matters is whether the answer is in the first sentence, whether it contains specific details (a number, a condition, a deadline) and whether the headings answer customers’ questions. In a study conducted by Princeton and IIT Delhi Including quotations and figures in the text increased its presence in the responses generated by generative models by around 30–40%, whilst cramming keywords It didn’t help. AEO is part of GEO, which involves work on brand visibility in AI: it determines whether the content can be quoted, not whether the model exists at all is familiar with the brand.

Definition

Why have a separate concept of AEO?

Because the AI chatbot doesn’t summarise the entire page; it simply takes a ready-made excerpt from it, and AEO ensures that such an excerpt is present in the text. It searches for an excerpt that can be provided as a ready-made answer, and usually takes it in its entirety. AEO describes the work involved in ensuring that such a passage exists in your text in the first place.
That is why two pages on the same topic can come across quite differently. One begins with three paragraphs on how important the topic is. The other answers the question and sets out the conditions in the very first sentence. The model will choose the latter.
AEO does not replace work on references outside your own domain. It determines whether your content is quotable, rather than whether, Does the model even know who you are?. The latter is dealt with in greater detail GEO.
AEO in a nutshell

Write in such a way that the model can take a ready-made snippet from your page and provide it as a response.

FormThe answer at the start, not after three introductory paragraphs
The point isNumbers, terms and names rather than generalities
StructureHeadings and data that the model uses to navigate

Full name: Answer Engine Optimisation. It is sometimes described as the editorial and technical aspect of GEO.

Mechanism

Which part of the page does the AI chatbot use to generate its response?

The one that directly answers the question in the headline and provides specific details. The same content, written in two different ways, produces a completely different effect. Below are two versions of the same topic.
The model has nothing to take
How much does [the service] cost?

These days, more and more companies are thinking about costs. It is worth bearing in mind that every project is different, and the price depends on many factors…

We therefore encourage you to get in touch for a personalised quote…

Three paragraphs, nothing concrete. There isn’t a single passage that could be quoted as an answer.

The model takes the first paragraph
How much does [the service] cost?

The cost usually ranges from X to Y, and is determined by three factors: the scope, the deadline and the number of revisions.

Below, we break each of them down into their constituent parts and give some examples…

Excerpt ready for quotation

The answer is in the first sentence; the conditions are stated explicitly, with the rest providing further detail.

The difference lies not in the length or the number of keywords, but in where the answer is found. In our analyses, the models most frequently cite the beginning of the section.
Practical experience

How to write content for AEO? Six rules

The answer right at the start, headings that act as questions, concrete details rather than adjectives, one topic per page, structured data and open access for search engine bots. All of these can be implemented without having to rewrite the page from scratch.
The answer at the beginningFormThe first sentence answers the question in the headline. The explanation follows below, not the other way round.
A headline in the form of a questionForm„How much does it cost?” instead of „Price list”. The models adapt the headings to the queries, and people ask questions in full sentences.
A noun instead of an adjectiveContentTimeframes, deadlines, conditions, figures. „Comprehensive service” isn’t suitable for a quote, but „from X to Y working days” is.
One topic, one pageStructureA subpage that answers a single question is easier to quote than a general article covering everything.
Company detailsTechnologyTags explaining what the website is about, what you sell and where you operate. The model then doesn’t have to work it out from the text alone.
Access for botsTechnologyIf the model bots are blocked from accessing the site, the rest of the work is pointless. It’s worth checking what’s blocking the server.
We also apply these principles to the materials we produce in Study, and the website is checked in this regard audit in the module Visibility.

How does an AEO differ from a GEO?

AEO is part of GEO: it only concerns whether content can be quoted, whilst GEO also covers mentions of the brand outside your website. This is most clearly illustrated in the diagram: one is part of the other.
GEO

Does the model mention the brand at all? It covers content on its own domain, signals from outside it, and the possibility of being cited.

AEO

Can a ready-made answer be extracted from your text? Form, specificity, structure.

Opinions and reviews Rankings and directories Industry publications Speeches

These four things fall within the scope of GEO but outside that of AEO. None of them depends on how you write your own page.

The practical implication is that AEO status alone leads the brand to visibility threshold and that’s where it stops. The text is ready to be quoted, but the model still has no reason to, to choose you, of all people. We describe the third concept – traditional SEO – in the article What is SEO?, and we list all three in comparison.
To be honest

What won’t an AEO do?

AEO won’t make an AI chatbot start recommending your brand: it provides content to quote, but not a reason to choose you specifically. Here are four things worth knowing before you rewrite the entire page.
A well-written website is not enoughAEO is responsible for ensuring that you can be quoted, not for the reason why the model would choose you in particular.
This isn’t writing to suit an algorithmIt’s not about cramming in phrases or writing for machines. Getting straight to the point and being specific helps people too.
No single file is enoughInformation about the company and llms.txt They help, but they are no substitute for content that contains something worth quoting.
You can see the result in the next measurementThe model must revisit the page and take the change into account. This does not take place on the day of publication.
FAQ

Questions about AEO

The questions we hear most often when working on content.
What is an AEO?

AEO, or Answer Engine Optimisation, involves preparing content in such a way that an AI model can extract a ready-made answer from it and cite it as a source. It relates to the form and structure of the text.

Is AEO the same as SEO writing?

No. SEO focuses on a website’s position in search results, whilst AEO focuses on whether the model can extract a snippet of the answer from it. We compare the two in this article SEO, GEO and AEO.

Does AEO also apply to Google AI Overviews?

Yes. AI Overviews also construct their answers from snippets of web pages and display links to the sources. Google states that no separate tags are required for this: basic SEO and content that can be quoted are sufficient.

Where should you start with your own website?

Let’s go back to the beginning. Take the three most important subpages and check whether the first paragraph answers the question in the heading. It usually doesn’t.

Do I need to rewrite the whole page?

No. You simply need to start with the subpages that answer customers’ actual questions: services, prices, deadlines and terms and conditions.

Is llms.txt necessary?

No. It helps models identify relevant content, but without content that contains something worth quoting, it does not change the result. We explain the concept in dictionary.

How can you check whether the AEO has worked?

After the next measurement at the same set of queries: is growing citation index, i.e. the proportion of responses in which the model refers to your domain. At the lime manufacturer’s The website’s citation index rose from 6% in June to 94% in September 2026.
