SEO or AEO: where the difference lies and what to do now
AEO is not the successor to SEO, nor is it the same thing under a new name. Both aim at visibility, but they reward different things — and in three places they actively contradict each other. Where, and what follows from that.
In short
- SEO aims at a place in a list; AEO aims at being named in an answer. The first brings clicks, the second brings mentions.
- Around two-thirds of the work is identical: clean structure, fast pages, clear hierarchy, real substance.
- Three points genuinely conflict: text length, narrative build-up, and how you treat the click.
- Starting today means getting the basics right first — they pay into both — and then adding the four AEO-specific measures.
The short version: search engine optimisation makes sure your page appears in a results list and gets clicked. Answer engine optimisation makes sure a language model uses your statement in its answer — with or without a click.
That sounds like a detail and is a fundamentally different target. A result in first place gets found. A statement in an answer gets passed on.
Side by side
| SEO | AEO | |
|---|---|---|
| Goal | a place in a results list | a mention in a generated answer |
| Success looks like | a click through to your page | a mention, often without a click |
| What is assessed | the page as a whole | an individual section or sentence |
| What is rewarded | depth, breadth, links | clarity, verifiability, position of the answer |
| Text structure | build-up, then the answer | answer first, then the reasoning |
| Measured via | Search Console, position, clicks | server logs, mention checks, referral sources |
| Effect after | 3 to 6 months | weeks to a few months |
What applies to both — roughly two-thirds of the work
Before the differences: the bulk of the work pays into both. Without these basics there is no point thinking about AEO at all.
- The page has to be readable in the first place. Content that only appears through JavaScript is not picked up by some AI crawlers — and unreliably by search engines.
- Heading hierarchy without gaps. One H1, H2s below it, H3s below those. Both sides use it to separate sections.
- Load time. Crawlers have a time budget. A slow page gets fetched less often and less completely.
- Having something of your own to say. Summarised general knowledge does not rank and does not get quoted. Your own figures, your own experience, a nameable position — that is the basis for both.
- Making currency visible. A last-reviewed date that is true.
Worth knowing
Answer engines draw a substantial share of their sources from the same search results people see. If you are invisible in conventional search, you rarely turn up in the answers either.
The reverse does not hold: a page can sit at position three and still never be quoted — because its statements are buried in flowing prose rather than standing there as clear, extractable sentences.
The three points where the two conflict
This is where it gets uncomfortable, because you have to choose.
1. Text length
SEO rewarded length for years: 2,500 words beat 900. AEO rewards the opposite — a model looks for the shortest passage that fully answers the question. A 2,500-word text without clear per-section answers offers nothing quotable.
Resolution: keep the length, but structure it. Every section answers one question completely in its first two sentences. The text stays long but is built out of short answers.
2. Narrative build-up
Good journalism leads you in: context first, then the insight. For answer engines that is fatal — the answer sits in paragraph seven, and what gets extracted is paragraph one.
Resolution: answer first, reasoning after. That costs dramatic shape and gains quotability. For technical writing it is the right trade; for narrative formats it is not.
3. How you treat the click
SEO wants the click and therefore holds something back. AEO gives the answer in full — and accepts that some readers never land on the page, but do register the brand as a source.
Resolution: this is a strategic decision, not a craft one. If you earn from ad impressions you cannot give everything away. If you earn from projects, holding back loses you more than it gains.
The third point is where most discussions get stuck. The worry runs: "if the AI gives the answer, nobody comes to us any more."
For ad-funded media that worry is justified. For a company selling projects it usually is not: being named as a source in an answer puts you in front of someone actively looking for a solution, carrying a recommendation that did not come from you. That is something other than a page view, and in many cases worth more.
Two lists of measures
Both lists are sorted by effect per effort. Starting from scratch means working through the left one first.
SEO – the first five steps
1. Set up Search Console and rework the queries sitting at position 5 to 20.
2. Fix one main term for each important page — exactly one.
3. Write titles and descriptions that name the result.
4. Internal linking: every piece points to two or three related ones.
5. Check load time and remove the three biggest brakes.
AEO – the first five steps
1. An "in short" section at the very top of every piece.
2. Every H2 as a question or clear statement, answer in the first two sentences.
3. A questions section at the end, each answer understandable on its own.
4. Structured data: Organization, Article, FAQPage, BreadcrumbList.
5. In robots.txt, decide which AI crawlers are allowed — deliberately, not by accident.
How to measure both
For SEO the measurement is settled: Search Console, position, clicks, queries.
For AEO there is no official console. Three approaches are workable:
- Read the server logs. Requests from GPTBot, PerplexityBot, ClaudeBot and the rest show whether your pages are being read at all.
- Referral sources in analytics. Visitors arriving from chat and answer services show up as their own source — small volume, but strikingly long time on page.
- Ask fixed questions regularly. Twenty questions from your field, asked once a quarter across several systems, results noted. Rough, but repeatable — and repeatable is worth more than precise.
Check the following piece for whether an answer engine could quote it. Piece: [paste text] Rate these five points, each with a score from 1 to 5 and a concrete justification from the text: 1. Does a complete, extractable answer appear at the start? 2. Does every section answer its heading in the first two sentences? 3. Are the statements understandable without the surrounding text, or do they refer to "above", "as mentioned", "it depends"? 4. Are there verifiable, original details (figures, methods, experience) or only generalities? 5. Is it apparent who wrote this and when? Then name the three paragraphs most likely to be quoted, and the three that would be incomprehensible once extracted. For those three, write a better version.
In closing
AEO does not replace SEO. It comes on top — and costs less additional work than the new acronym suggests, because two-thirds of the groundwork is the same anyway.
The real shift is not technical but in the writing: answer first, reasoning after, every section understandable on its own. Change that and you lose a little dramatic shape and gain on both fronts.
Common questions
What is the difference between SEO and AEO?
SEO aims at ranking high in a results list and being clicked. AEO aims at a language model using a statement from your page in its generated answer — often without a click. SEO assesses the page as a whole; AEO assesses the individual section.
Does AEO replace conventional search optimisation?
No. Answer engines draw a large share of their sources from the same search results people see — if you are conventionally invisible, you are rarely quoted either. AEO comes on top of SEO, and around two-thirds of the work is identical anyway.
Where do SEO and AEO conflict?
In three places: text length (SEO rewards depth, AEO rewards brevity per section), structure (SEO tolerates build-up, AEO demands the answer first) and the click (SEO holds something back, AEO gives the answer in full). The first two can be resolved by building a long text out of short answers.
How do you measure AEO success?
Three ways: AI crawler requests in the server logs, visitors arriving with chat and answer services as their referral source, and a fixed list of around twenty questions asked quarterly across several systems and logged. There is no official console like Search Console.
Where do you start if you want both?
With the basics that pay into both: readable HTML that does not depend on JavaScript, a clean heading hierarchy, fast load time, and original, verifiable content. After that come the four AEO-specific steps — a summary at the top, answer first in every section, a questions section at the end, and structured data.
