In one sentence: SEO optimises for retrieval of a document; AEO optimises for extraction of a self-contained answer from inside it — and a page can do the first perfectly while making the second impossible.
This is the narrower of the two comparisons people ask about. GEO asks whether the brand gets named across a whole answer; AEO asks a mechanical question about one page: can a correct, quotable answer be lifted out of it without the surrounding context?
Why extraction is where pages fail
An answer engine assembles a reply from passages. When it evaluates your page it is effectively asking: if I cut a hundred words out of here and paste them into my reply, will they still be true and still make sense? Pages fail that test for reasons that have nothing to do with content quality:
- The answer depends on the heading. A paragraph that begins “It costs £49 per month” is unusable; “The Pro plan costs £49 per month” survives the cut.
- The answer arrives late. Three paragraphs of context before the sentence that answers the question means the answering sentence may never be in the selected passage at all.
- The answer is spread across a table and a footnote. Anything that requires assembling two distant parts of the page is fragile.
- The answer lives in an accordion, tab or modal. If it isn't in the server-rendered HTML, most retrieval agents never see it.
- The page hedges. “Pricing varies by use case” cannot be quoted as an answer, so a page that says it will lose to a competitor page that states a number.
What AEO asks you to change
| Pattern | Instead of |
|---|---|
| State the answer in the first sentence under the heading, then explain | Building up to it |
| Repeat the subject in the sentence that carries the fact | Relying on pronouns and the heading |
| One question per heading, phrased the way a person would ask | Marketing headings |
| Facts in a table with real units and dates | Facts scattered through prose |
| FAQ blocks with the answer in the HTML, not only in the schema | FAQPage schema over content the page hides |
| Explicit dates on anything time-bound | “Recently”, “currently”, “this year” |
Where AEO and SEO disagree
Mostly they don't — but there are two real conflicts. Answer-first writing shortens time on page, which some teams still treat as a quality signal. And stating a specific number invites being wrong later, which is why so many pages hedge. Both conflicts resolve the same way: a page that gets quoted is worth more than a page that keeps someone reading, and a number with a date on it is safer than a vague claim, because the date tells the reader — and the engine — exactly what it is and isn't claiming.
How to check a page in five minutes
Fetch the page as plain HTML with JavaScript off. Find the heading that matches a real question. Read the first two sentences under it, out of context. If they are a complete, correct answer that names its subject, the page passes. If you had to scroll up to understand them, it doesn't — and no amount of link building fixes that.
