AEO vs GEO vs AI SEO: what’s the difference?

AEO (Answer Engine Optimization), GEO (Generative Engine Optimization), and “AI SEO” are largely the same thing: getting your business named and cited inside AI-generated answers (ChatGPT, Google's AI Overview, Perplexity, Gemini) instead of just ranking a link. The label varies by vendor; the goal — and the work — is the same.

If three vendors emailed you about “AEO,” “GEO,” and “AI SEO” this week, they’re mostly selling the same thing. Here’s how the terms line up — and the one thing that actually decides whether AI names your clinic.

The terms, side by side

TermWhat it meansNuance
AEO — Answer Engine OptimizationBeing the cited answer when someone asks a question of an answer engine.Emphasizes the question→answer match (FAQs, extractable facts).
GEO — Generative Engine OptimizationSame goal; framed around generative LLMs specifically.Emphasizes the generative model (entity authority, citations).
“AI SEO”Catch-all marketing label for the above, riding the familiar 'SEO' term.Often used to sell it to people who already buy SEO.
SEO (traditional)Ranking a clickable link in the classic results list.Targets the blue link + the map pack — a different surface.

Bottom line: don’t pick a provider by which acronym they use. Ask what they’ll actually change on your site, and whether they’ll show you — with a search you can run yourself — that the AI answer moved.

Common questions

Is GEO the same as AEO?

Effectively yes. GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) describe the same practice — getting cited inside AI answers. 'GEO' stresses the generative model; 'AEO' stresses the answer. Pick the vendor by what they actually do, not the acronym.

Is AEO different from SEO?

Yes. SEO competes for a clickable link in the results list; AEO competes to be named inside the AI's written answer, before the user clicks anything. A business can rank #1 on Google and still be absent from the AI answer, so most clinics need both.

What does a med spa actually need?

Keep doing local SEO and reviews — they win the map pack. Add AEO on top so the AI answer for 'how much does Botox cost in <city>' or 'best med spa near me' names your clinic. The deciding factor isn't the acronym; it's whether your key facts are published where the AI can read and trust them.

Does schema or an llms.txt file make the difference?

Not on their own. Those are table-stakes; the businesses AI actually cites lead with a clear, extractable answer to the exact question (e.g. a real per-unit price in text) backed by sources the model can corroborate. Tooling helps, but it doesn't substitute for answering the question.
