SEO vs AEO vs GEO: what changes for medical and dental clinics

SEO, AEO and GEO appear together in every 2026 marketing talk, and many people use the three terms as if they were the same thing. They are not: SEO competes for positions on Google, AEO competes for the direct answer displayed by the search engine, and GEO competes for the recommendation inside ChatGPT, Gemini and other AIs. For clinics, the three layers work together and the priority has shifted.

At Bincoo, monitoring thousands of clinics, we see that the ones growing the most combine the three strategies with clear roles. This article shows how.

More than 10,000 companies already use Bincoo to be recommended by ChatGPT, Gemini and other platforms.

What each discipline actually does

Before comparing, it is worth understanding the role of each one:

• SEO (Search Engine Optimization): makes your clinic's pages rank in Google's classic results when someone searches 'dentist near me';
• AEO (Answer Engine Optimization): makes your content be selected as the direct answer, in answer boxes, voice assistants and automatic summaries;
• GEO (Generative Engine Optimization): makes conversational AIs cite and recommend your clinic's name when a patient asks where to get treated.

Full comparison: SEO vs AEO vs GEO

Criterion	SEO	AEO	GEO
Where it acts	Classic search results	Answer boxes and voice assistants	ChatGPT, Gemini, Perplexity and Claude
What it competes for	Position on the page	Being the single displayed answer	Being the recommended name
Ideal format	Full pages with keywords	Short, structured answers	Content with data, citations and authority
User interaction	Clicks the link and compares	Reads the answer without clicking	Receives a ready-made recommendation
Main metric	Position and traffic	Presence in the answer box	Share of AI answers
Typical investment	High and ongoing	Medium	Low to medium, with cumulative effect

What changed for clinics in 2026?

The patient journey moved beyond a single format. Some patients still search on Google and click links; there, SEO remains essential. Another group asks the AI directly and chooses among the recommended names; there, only GEO solves it. And the in-between Google, with automatic summaries at the top, demands AEO.

The practical conclusion: a clinic that invests only in SEO is prepared for an increasingly smaller slice of the journey. The patient who decides on ChatGPT will never pass through your site on Google.

Where to start: the right order

If you are starting from scratch, the order we recommend based on what works for clinics is:

1. Technical foundation and local SEO: healthy website, complete business profile, reviews;
2. Content that answers: pages per service with direct answers, covering SEO and AEO;
3. GEO: weekly publication of optimized articles and monitoring of AI answers;
4. External proof: mentions in portals and directories to sustain all three layers.

And the cost of each approach?

Here is the question every clinic owner asks. Well-done SEO requires an agency, link building and months of investment. AEO requires structure and content discipline. GEO, because it is still new, offers the biggest opportunity window: with a small investment, a local clinic can dominate AI answers before the competition wakes up.

That is exactly the window where Bincoo operates: with the Essential plan, at R$ 39.00/month (Brazilian reais), your clinic receives the optimized articles, the monitoring of AI answers and the weekly action plan, without hiring an agency.

Conclusion

• SEO, AEO and GEO compete for different moments of the patient journey and complement each other;
• A clinic that invests only in SEO stops competing for those who decide by asking an AI;
• The right order is foundation, content that answers, GEO and external proof.
