The short answer
AEO, answer engine optimization, is the work of making your page the answer people see: a featured snippet, an AI answer or a voice reply. SEO is the wider work of getting pages found and clicked in search. AEO sits on top of good SEO. It does not replace it.
What is the difference between AEO and SEO?
SEO aims to get your pages into the results and clicked. AEO aims to get your words used as the answer itself, often before anyone clicks.
The base is the same. A page that search engines cannot reach or index will not be an answer either.
| Question | AEO | SEO |
|---|---|---|
| Main goal | Be the answer people see, often without a click. | Rank pages in the results, so people click through. |
| Where the answer shows | Featured snippets, AI answers in search and in tools such as ChatGPT, and voice replies. | The list of results in Google, Bing and other search engines. |
| What you optimise | The same base as SEO, plus a direct answer at the top, questions as headings and clear facts with sources. | Crawling and indexing, pages that match real searches, internal links, links from other sites and speed. |
| How it is measured | Whether your brand is named or your page cited for the questions buyers ask, tracked with dates. | Impressions, clicks and positions in Search Console, then leads and sales. |
Do you need AEO if you already do SEO?
You need the parts of AEO that make pages easy to quote. Most of them are good SEO done properly.
Google says so plainly. Its guide to generative AI search says you do not need new machine-readable files or special markup to appear. It also says Google Search ignores llms.txt files.
What changes is the shape of the page. The answer comes first, each section answers one question, and every claim shows its source.

- The answer first. The first 40 to 60 words say what it is, who it is for and what to do next.
- Questions as headings. Each H2 is a question a buyer asks, so any section can be quoted alone.
- Clear facts about you. The same name, description and prices on every page that mentions them.
- Sources and dates. Every number shows where it came from and when it was checked.
- Pages that can be shown. Indexed, with a snippet allowed, which Google says its AI features need.
How do you measure AEO?
Start where you measure SEO: impressions, clicks and positions in Search Console. Then add what SEO reports do not show.
Write down the questions your buyers ask. Ask them in the AI tools your buyers use, and save the answers with the date. That dated record shows whether your brand starts to appear.
Our SEO plans track buyer questions this way: 25 on Starter, 50 on Growth and 100 on Scale.
Checklist: AI search basics
- Crawler access. The search crawlers you want can reach your pages.
- Indexed, with a snippet. Key pages are indexed and allowed a snippet.
- Answer first. Each page answers its main question at the top.
- Sources and dates. Every number on the page shows both.

AEO vs SEO: questions
Is AEO the same as SEO?
No, but it builds on it. SEO gets pages found and clicked. AEO shapes those pages so search engines and AI tools can use them as the answer.
Is AEO the same as GEO?
They overlap. AEO is the older term, from featured snippets and voice answers. GEO, generative engine optimization, is about AI-generated answers. See GEO vs SEO.
Do I need special files or markup for AEO?
Not for Google. Its guide says no new machine-readable files or special markup are needed, and that Google Search ignores llms.txt files.
How long does AEO take to show?
The same as SEO. Technical fixes can show within weeks, content usually takes three to six months to really move.
