SEO and AEO
SEO vs AEO: what is actually different
They share most of the same foundations, so the differences are narrower than the marketing suggests — but the differences that exist matter. A practical comparison.
SEO optimises for placement in a list of results a user will click. AEO optimises for being understood, quoted and correctly attributed when a system answers the question itself. They share most of the same foundations — crawlability, site structure, accuracy, depth and authority — so around eighty per cent of the work is identical. The remaining twenty per cent is worth understanding.
The comparison
| SEO | AEO | |
|---|---|---|
| Goal | Rank in a list of links | Be understood and quoted |
| Success looks like | A click | An accurate mention, with or without a click |
| Unit of value | The page | The passage and the entity |
| Content shape | Comprehensive coverage of a topic | Direct answers, cleanly extractable |
| Critical signal | Links and relevance | Consistency and clarity |
| Structured data | Helps rich results | Central to being understood |
| Measurement | Rankings, traffic, conversions | Difficult and largely indirect |
| Guarantees possible | No | No |
Where they genuinely overlap
Nearly all the foundational work serves both:
- A crawlable, fast, well-structured site
- Semantic HTML with a heading hierarchy that reflects real structure
- Content that satisfies the intent behind the query
- Internal linking with descriptive anchor text
- Accurate structured data
- Genuine authority in the subject
If someone proposes an AEO engagement that does not touch any of this, ask what exactly they are doing.
Where they actually differ
Consistency becomes a primary signal
In SEO, inconsistent business details across platforms is a minor local-search problem. In AEO it is central: a system trying to state a fact about you needs corroboration, and contradictory sources produce either a hedge or a wrong answer.
The extractable passage matters more than the page
SEO rewards a page that comprehensively covers a topic. Answer engines pull passages. A page can rank well and still be almost impossible to quote, because the answer is distributed across six paragraphs and three qualifications.
Being the original source matters more
Aggregated content can rank. It is much harder to cite, because there is nothing in it that is yours. First-hand experience, original data and specific detail are what get attributed.
Measurement gets harder
This is the honest difficulty. SEO has rank trackers, Search Console and clean attribution. AEO has none of that. You can sample what assistants say about you, watch branded search, and check your structured data — but you cannot produce the tidy dashboard clients are used to, and pretending otherwise is how this discipline will earn a bad reputation.
Does AEO replace SEO?
No. Most searches still produce links that people click, and organic traffic remains the larger commercial channel for most businesses. AEO is an additional lens on the same underlying work, not a successor to it. Reallocating an SEO budget to AEO on the assumption that clicks are finished would be a costly misreading of the current situation.
What to do about it
- Fix consistency first — name, address, description and services identical everywhere
- Add a direct answer under every heading that asks a question
- Make structured data match the visible page, and validate it
- Publish what only you can write: real projects, real numbers, real mistakes
- Keep doing the technical SEO work, because it underpins both
Notice that four of those five are things a competent SEO practitioner would already recommend. That is the point.
