AEO vs SEO: what is the difference?
SEO optimises to rank a page in a list of search results a person clicks through. AEO optimises to be cited inside the single answer an AI engine writes instead of that list. SEO wins traffic; AEO wins the recommendation. Most businesses now need both, because buyers use both.
| Attribute | SEO | AEO |
|---|---|---|
| Goal | Rank in the list of links | Be cited in the AI-generated answer |
| What you win | Clicks and traffic to your site | A mention in the answer buyers read first |
| The unit | Keyword rankings and pages | Citations and entity mentions |
| Where it shows | Google and Bing results pages | ChatGPT, AI Overviews, Perplexity, Gemini |
| Core tactics | Keywords, backlinks, page speed, titles | Answer-first content, JSON-LD schema, entity clarity, corroboration |
| How buyers behave | Scroll and choose from a list | Read one answer, often without clicking |
| How you measure | Rankings, impressions, organic traffic | Citation share, which sources the answer names |
| Timeframe | Months to move competitive rankings | Days to weeks for on-page fixes, longer for trust |
They are not rivals
Most AEO signals, clean structure, clear entities, genuinely useful content, also help SEO. The difference is the target: SEO chases a position in a list, AEO chases a place inside the answer. You can rank well and still be missing from every AI shortlist, because the engine reads your page differently from how a human skims it.
Which one you need
- Buyers cannot find you at all: you need both. Fix the traditional visibility and the AI citability together.
- You rank but AI ignores you: you have an AEO gap specifically. The traffic is there; the recommendation is not.
- Your market has moved to AI-first research: AEO stops being optional. The answer is now the shortlist.
A concrete example
Search 'hair transplant clinic in Bangkok' on Google and you get a page of links to scroll. Ask ChatGPT the same thing and you get a short answer that names two or three clinics. SEO decides who is in the list. AEO decides who gets named in the answer. Different games, same buyer.
No. It sits alongside SEO. As more buyers start their research inside AI engines, AEO becomes the visibility that decides the shortlist, while SEO still governs the clicks that follow.
Partly. Clean structure and useful content help both. Schema, entity clarity and third-party corroboration matter far more for AEO than they do for a traditional ranking.
No. Strong SEO fundamentals feed AEO, and traditional search still sends real traffic. AEO is an addition, not a replacement.
It depends where your buyers start. If they increasingly ask an AI engine before they ever search or visit a site, the AEO gap is the one costing you deals you never see.

Ranking is not the same as being chosen.
The AEO audit shows exactly where you are, and are not, cited in the AI answers your buyers read first.
