What is AEO, and how is it different from SEO? (2026 guide)

Quick answer: AEO (answer engine optimisation) is the work that makes AI assistants such as ChatGPT, Perplexity, Gemini, and Google AI Overviews name your business and describe it correctly. SEO puts your page high in a list of links. AEO puts your business inside the answer. AEO uses the same foundations as SEO, but it measures the answer, not the rank.

As of October 2026, buyers get more of their shortlist from AI answers than from a page of blue links. SEO wins the click. AEO wins the mention. A business needs both, but most small businesses only measure the first one.

This guide explains what AEO is, how it differs from SEO, and the five checks that you can do this week.

What does AEO measure that SEO does not?

AEO measures whether an AI assistant names your business when a buyer asks a question, and whether the facts in that answer are correct. SEO measures the position of your page in a list of results.

A ranking report can say that your page is in position 4 for “accountant for startups Adelaide”. It cannot tell you what a buyer sees when they ask an AI assistant the same question. The assistant can name three firms, and yours is possibly not one of them.

For this reason, AEO starts with a different test. You ask your buyers’ questions in each assistant, and you record three things:

1. Is your business in the answer?
2. Which competitors are in the answer?
3. Is each fact about you correct?

Key takeaway: Rankings are an input. The AI answer is the output that your buyer sees.

Why does the answer matter more than the click?

The answer matters more because fewer people click past it. Pew Research Center, a US research organisation, tracked the browsing of 900 US adults in March 2025. When Google showed an AI summary, users clicked a traditional search result in 8% of visits, against 15% when no summary appeared. They clicked a link inside the summary in only 1% of visits.

For a small business, the result is simple. If the summary names your competitor and not you, most buyers do not scroll down to find your page. Your page in position 4 gets fewer visits than before, even if the rank does not change.

Key takeaway: The AI answer is the new shortlist. A buyer who does not see you there often does not see you at all.

Do AI assistants only cite the top 10 results?

No. A high rank helps, but it is not enough. A Conductor analysis of about 168 million AI Overview citations found that 57% of the cited pages were outside the organic top 10 for the same search. Ahrefs data, reported by Search Engine Journal, found that only 38% of cited pages also ranked in the top 10. The studies use different methods, but they agree on the direction.

Google explains part of the reason. Its documentation for site owners says that AI Overviews and AI Mode can use a “query fan-out” method. The system runs several related searches across subtopics, and then builds one answer. A page that answers a narrow sub-question clearly can be cited, even if it does not rank for the main phrase.

Key takeaway: Clear answers to specific questions can earn a citation without a top-3 rank.

What stays the same as SEO?

The foundations stay the same. Google states that a page is eligible to be a link in AI Overviews and AI Mode if it is indexed and eligible to show in Search with a snippet. There are no additional technical requirements. Google’s guidance on AI features tells site owners to focus on unique, useful content for people.

These SEO basics still carry the most weight:

• Google and the AI crawlers can open and index your pages.
• Each service has its own page, with real text, not text inside images.
• Page titles and descriptions say what each page is about.
• Your business name, address, and phone number are the same everywhere.

If these basics are broken, fix them first. No AEO work makes an assistant cite a page that it cannot read.

What does AEO add to SEO?

AEO adds three types of work that a typical SEO programme does not put first.

1. Direct answers on your own pages. Assistants pull short, specific statements. A page that says “We do bookkeeping for startups in Adelaide, for a fixed monthly fee” gives the assistant a fact that it can repeat. A page that says “We offer tailored financial solutions” gives it nothing. Put the buyer’s question in a heading. Answer it in the first two sentences under the heading.

2. Correct facts about you on other websites. Assistants compare what other sources say about you. Directories, review sites, “best of” lists, partner pages, and industry articles all count. If three directories still show your old address, the assistant can repeat the error.

3. A place on the sources that the assistant trusts. Perplexity and Google show the pages that they used for each answer. Those pages are your target list. If the same two directories appear in most answers in your category, your business needs to be on them, with correct details.

Key takeaway: SEO makes your pages eligible. AEO makes your facts easy to find, easy to repeat, and confirmed by other sources.

How do you start with AEO?

You can run a first AEO check in one afternoon, without a tool:

1. Write 10 questions that your buyers ask before they buy. Use their words.
2. Ask each question in ChatGPT, Perplexity, Gemini, and Google. Use a private browser window.
3. Record which businesses each answer names, and if you are one of them.
4. Write down each wrong fact about your business.
5. Record the sources that each answer cites.

Repeat the same 10 questions each month. AI answers change often, so one check tells you little. The trend over three to six months shows if your work has an effect. Our free AI Search Visibility Checklist gives you 20 checks in this order. For a fast first test, use our 15-minute ChatGPT check.

Frequently asked questions

What does AEO stand for?

AEO stands for answer engine optimisation. An answer engine is a tool that gives a direct answer, not a list of links. ChatGPT, Perplexity, Gemini, and Google AI Overviews are answer engines. AEO is the work that makes these tools name your business and state correct facts about it.

Is AEO replacing SEO?

No. AEO builds on SEO. Google states that pages need to be indexed and eligible for Search to appear in its AI features. Without SEO foundations, AI assistants cannot find your pages. Treat SEO as the foundation and AEO as the layer that decides if the answer includes you.

What is the difference between AEO and GEO?

The two terms describe almost the same work. GEO (generative engine optimisation) comes from a 2023 research paper by researchers at Princeton and other institutions that tested ways to make sources more visible in AI answers. AEO is the more common term in marketing. Both aim to get your content cited in AI answers.

How long does AEO take to show results?

Expect weeks to months, not days. Fixes to your own pages can show faster, because assistants with web search read pages at the time of the question. Changes that depend on other websites, such as new listings and articles, take longer. Measure each month to see the trend.

Does schema markup help AEO?

Not directly. Google states that AI Overviews and AI Mode need no special markup. Organization and Service markup still help search engines understand who you are and what you sell, if the markup matches the visible text. Clear, specific text on the page matters more than any markup.

Can a small business compete with large brands in AI answers?

Yes. In a narrow category, such as one service in one city, the number of sources that assistants use is small. A small business that fixes its pages, corrects its listings, and gets onto the few lists that the assistants cite can appear in answers in weeks to months. Large brands win on volume. Small businesses can win on clarity.

Can anyone guarantee a position in ChatGPT?

No. Nobody controls the output of an AI model. Be careful with any offer that promises a guaranteed position. You can control the inputs that the model reads: your pages, your listings, and what other websites say about you. Then you measure the result each month.

How do I track my AEO results?

Ask the same set of buyer questions in the same assistants each month, and record the answers in one table. Count how often your business appears, which competitors appear, and how many facts are wrong. As of October 2026, Google Search Console also includes AI Overview and AI Mode traffic in its Performance report.

AEO and SEO are one programme

• AEO makes AI assistants name your business and state correct facts about it.
• SEO makes your pages eligible. AEO decides if the answer includes you.
• AI assistants often cite pages outside the top 10, so clear answers matter as much as rank.
• Start with 10 buyer questions, four assistants, and one table. Repeat each month.

At 2102, an AI-assisted content programme for a medtech client gave a 25% lift in search visibility. The method was the one in this guide: answer the real questions directly, fix the facts, and measure each month.

If you want to know what AI assistants say about your business today, our AI search visibility service starts with that audit: 10 buyer questions, tested in each assistant, with a ranked fix list.
