SEO asks: do you rank in a list of results? AEO asks: when the AI gives one answer, is it you? The disciplines share most of their substrate, but they are measured in different units, optimised against different systems, and today they are rarely done by the same people.
| SEO | AEO | |
|---|---|---|
| The question | Do you appear in the results list, and how high? | Does the AI's answer name you, or a competitor? |
| Measured in | Rankings, impressions, clicks | Share of answers that recommend you, per engine |
| The gatekeeper | One index (mostly Google) | Several assistants that disagree with each other a third of the time |
| Failure mode | Page 2 of results, fewer clicks | Invisible: the customer never sees a list at all |
| Tooling | Mature (Search Console, rank trackers) | Young: monitoring exists, the fix-and-prove loop mostly doesn't |
| Who does it today | Your SEO person or agency | Usually nobody |
Where they overlap, and why that's good news
Machine-readable pages, accurate structured data, visible freshness, real HTML instead of graphics, citations in trusted sources: what makes the AI name you is largely what makes Google rank you. Done properly, AEO work compounds your existing SEO rather than competing with it, we just aim the same substrate from the answer side. Keep your SEO team; give them better ammunition.
Common questions
Does AEO replace SEO?
No. Google still drives most discovery today, and the substrate overlaps: machine-readable pages, structured data, freshness and authority help both. AEO is the additional layer that measures and optimises whether AI assistants name you, which classic SEO tooling does not track.
Do I need both AEO and SEO?
If customers research your category, yes, eventually. Practical order for most owner-led businesses: keep your existing SEO going, add AEO measurement to find where AI answers hand your leads to competitors, then fix the overlap first, the same work often pulls both channels.
Does AEO work help my Google rankings too?
Largely, yes. What makes an AI name you, extractable content, accurate structured data, fresh dated pages, citations in trusted sources, is substantially what makes Google rank you. The difference is aim: AEO starts from the answer and works backwards.
