What AEO (Answer Engine Optimization) is, vs. SEO

AEO (Answer Engine Optimization) is fitting your content to the way answer engines like ChatGPT, Gemini and Perplexity build an answer. The difference from SEO is not in the technique but in the outcome: SEO fights for a place in a list of links the user chooses from, while AEO fights for a mention inside the single answer the user already receives. In ordinary search, fifth place still brings traffic; in a model's answer, whoever was not mentioned simply does not exist. That is why AEO is measured in mentions and share of voice, not in rankings and clicks.

What is AEO?

AEO is the work of making a business, a brand or a source of information part of an answer an answer engine produces. When someone asks ChatGPT from OpenAI, Gemini from Google, Perplexity or Claude from Anthropic a question, they usually do not want to choose among ten links. They want a useful answer now. Sometimes the answer includes names of businesses, sources and recommendations; sometimes it includes none of them.

That is where the structural difference comes from. In SEO the unit of success is a page that appears in the search results. In AEO the unit of success is a mention inside the answer. The site still matters a great deal: it is where the engine can find a clear definition, consistent facts, a business identity and a source a claim can be attributed to. But the mere existence of a ranked page does not guarantee that your name will enter the final wording of the answer.

AEO is not an attempt to persuade the model. It is orderly work on content that is easy to understand, check and cite: a direct answer to a question, full names of entities, a clear structure, consistent details and sources that can be identified.

How AEO actually differs from SEO

• The question: What is the unit of success?
• SEO: A link in search results
• AEO: A mention inside an answer
• The question: How is it measured?
• SEO: Position, impressions, clicks and traffic
• AEO: Mention rate, share of voice and position inside the answer
• The question: What does the user do?
• SEO: Chooses a link and visits the site
• AEO: May get an answer without visiting the site at all
• The question: How is the source chosen?
• SEO: The search engine ranks pages for a query
• AEO: The answer engine composes wording from sources and the knowledge available to it
• The question: What needs to be clear?
• SEO: That the page matches the phrase and the search intent
• AEO: Who you are, which question you answer and which claim can be attributed to you

The table does not say that one tool has replaced the other. Google still shows ordinary search results, Bing still crawls and indexes sites, and Google AI Overviews adds summarised answers above some of the results. At the same time, ChatGPT, Gemini, Perplexity and Claude offer an interface in which the answer itself is the product.

The measurement is different too. A ranking is a position in a relatively stable list. A model's answer can change across phrasings, moments and model versions. That is why a good AEO check does not rest on one question: it examines a set of relevant questions over time and compares the mention rate against competitors.

It is important to be precise: checks through an API are not word-for-word what a particular person sees in the ChatGPT app. They do not necessarily include memory, personalisation, browsing mode or the same model version. Their advantage is a consistent comparison over time and across businesses, not a perfect reconstruction of every customer's screen.

Why is this happening now, of all times?

The habit of use changes at the moment it becomes possible to ask a full question and get a full answer. Instead of searching “strategic consultant Tel Aviv”, opening several tabs and comparing on your own, you can ask in Hebrew: “how do you choose a strategic consultant for a business in Tel Aviv, and what is worth checking before you get in touch?” The answer engine gathers the explanation, and sometimes also names and sources, onto one screen.

The shift is from ten possible links to one written answer. It is especially visible in questions where the user wants to understand, compare or prepare a short list. Hebrew-speaking users ask questions in Hebrew and expect to get answers in Hebrew. A business whose information is vague, scattered or contradictory makes it hard for the engine to know when it is right to mention it.

There is no need to invent adoption figures to see the practical meaning. It is enough to check the questions real customers ask, see which names appear in the answers, and repeat the same check consistently.

What are answer engines actually looking for?

There is no single magic list, and each engine has its own way of working. Even so, content that is useful to an answer engine tends to be clear on three layers: what is said, who is saying it, and how the information is arranged.

On the content layer, it is worth answering one question directly at the start of the page. Definitions, comparisons, steps and short answers to common questions are easier to extract than a general opening paragraph. Explicit names matter: ChatGPT and not “an AI tool”, Anthropic and not “a model company”, and Tel Aviv and not “the central region”.

On the identity layer, the business name, the field of activity, the address, the people in the roles and the connections between the pages need to be consistent. An engine should not have to guess whether two different spellings describe the same entity. Reliable external sources and consistent mentions can help establish the connection, but no single source guarantees an appearance.

On the technical layer, schema.org lets you describe entities and content types in an agreed structure. JSON-LD is a common format for embedding that information in the page's code. For example, Organization describes an organisation, Article describes an article and FAQPage describes a set of questions and answers when it actually exists on the page. The markup is not an entry ticket into an answer; it simply reduces ambiguity.

llms.txt is also meant to offer AI systems a readable map of a site's content. It is a proposed file and not a standard that binds OpenAI, Google, Anthropic or Perplexity, so it is not right to promise that it will change a result. It can complement an orderly site, but it will not fix weak content, a crawl block or contradictory details.

Is SEO dead?

No. SEO is not dead, and AEO does not excuse a site from its foundations. An answer engine still needs to discover pages, read them, understand their structure and judge whether they are a reasonable source. Crawling, internal links, speed, clear headings, authority and external links continue to feed both search and answers.

The difference is that organic success no longer ends with a click. A page can help a user even when an engine quotes or summarises it without a visit. Conversely, a good ranking in Google does not automatically mean that Gemini, ChatGPT or Perplexity will choose to mention the business.

So the practical approach is not “SEO or AEO”, but a sound SEO foundation and content that is also designed for an answer. There is no point building advanced markup for a page engines cannot crawl, and no point bringing an engine to a page that does not clearly answer the question.

Where do you start?

1. Which questions actually lead to a choice?

Write down the full questions a customer asks before choosing a supplier, a product or a professional. Not only short keywords, but phrasings such as “which firm fits a company of our size?” or “what is the difference between two ways of handling this?” Start with a small set you can check again, not with hundreds of variations.

2. Who appears in the answers today?

Run the same questions in ChatGPT, Gemini, Perplexity and Claude. Record who is mentioned, in what context and which sources appear. Repeat the check at fixed times and in consistent wording. Do not turn a single answer into a conclusion about the whole market.

3. What should you fix first?

Pick one clear gap: a page that does not answer directly, business details that are not consistent, content without an author or a source, or a structure that is missing a matching Article, Organization or FAQPage. Fix it, publish, and check again. AEO is a cycle of measurement, a fix and measurement again, not a one-time installation.
