Two hundred and thirty million people ask ChatGPT health questions every single week. Not every month — every week.
That number comes straight from OpenAI. And it does not include Perplexity, Gemini, Claude, or the AI Overviews that now appear on 88% of all healthcare-related Google searches.
People are not just Googling their symptoms anymore. They are having conversations with AI about their health, their conditions, and — increasingly — which doctor they should see.
The question for your practice is simple: when AI answers, does it know you exist?
The search volume is massive
Here are actual monthly search volumes for healthcare keywords in the United States:
| Keyword | Monthly Searches | |---|---| | Urgent care near me | 2,740,000 | | Dentist near me | 1,200,000 | | Doctor near me | 800,000–1,000,000 | | Therapist near me | 500,000–800,000 | | Back pain | 500,000+ | | Eye doctor near me | 200,000–400,000 | | Dermatologist near me | 200,000–400,000 | | Chiropractor near me | 200,000–350,000 | | Pediatrician near me | 150,000–300,000 | | Symptoms of diabetes | 200,000–300,000 | | Symptoms of anxiety | 150,000–250,000 |
That is over 7 million monthly searches just for these terms. The full universe of healthcare queries — every symptom, condition, specialist, and treatment people search for — runs into the hundreds of millions.
And the behavior behind these searches is decisive:
- 77% of patients begin their healthcare journey on Google
- 84% check online reviews before choosing a provider
- 51% read a minimum of six reviews before deciding
- 40% have canceled or changed an appointment based on what they found online
- 89% of Gen Z and 75% of Millennials use AI tools to research conditions and compare providers
These are not people idly browsing. They are choosing who to trust with their health — and they are making that decision based on what they find online.
Where those searches actually go
Here is where the traffic lands:
| Platform | Monthly Visits | |---|---| | WebMD | 130–140 million | | RVO Health (Healthgrades, Healthline, Medical News Today) | ~70 million | | Healthgrades | ~30 million | | Zocdoc | 6–8.75 million | | Doximity | ~6.3 million | | Vitals.com | 1.7–3 million | | Average independent practice website | 500–2,000 |
A single health directory gets 10,000 to 100,000 times the traffic of a typical independent practice website. WebMD alone captures more visits in a day than most practices get in a decade.
Your potential patients are searching. They are just finding WebMD, Zocdoc, and Healthgrades instead of you.
The cost of buying what you could earn
Healthcare Google Ads are expensive and getting more expensive — CPCs have risen 40–60% over the past three years while conversion rates have stayed flat or declined.
| Specialty | Cost Per Click | |---|---| | Plastic / cosmetic surgery | $15–50+ | | Dermatology | $8–25 | | Orthodontics | $8.76 | | Hearing aids and care | $8.00 | | Emergency dentistry | $7.85 | | Primary care | $3–8 | | Mental health | $4.22 (but rising 42% year-over-year) |
The industry average CPC is $5.64, up 6% year-over-year. Specialty practices need to spend $5,000 to $15,000 per month minimum to compete effectively on Google Ads. And conversion rates decreased in 7 of 16 healthcare subcategories last year.
You are paying more to reach fewer people who are less likely to convert. That is the paid search treadmill.
Now here is where it gets serious: AI is rewriting healthcare discovery
Everything above is the traditional game — and it is already stacked against independent practices. But there is a structural shift happening right now that makes all of it look like a warmup.
88% AI Overview coverage
Google AI Overviews now appear on 88% of all healthcare-related queries. Treatment and procedure queries have 100% coverage — every single search for a treatment or procedure now gets an AI-generated answer before any organic results.
When those AI Overviews appear, healthcare has the highest zero-click rate of any industry: 83%. That means 83 out of 100 people searching for healthcare information never click on any website. The AI answered their question. They are done.
Organic click-through rates drop to 8% when an AI Overview is present, compared to 15% without one. Even the biggest names in healthcare are feeling it — Cleveland Clinic, Mayo Clinic, and Cedars-Sinai have all seen 10%+ month-over-month declines in organic traffic.
If the giants are losing ground, imagine what this means for a practice with 1,000 monthly visitors.
The 13x conversion advantage
Here is the number that should change how you think about all of this:
Leads from AI sources convert at 27%. Leads from traditional search convert at 2.1%. That is a 13x improvement.
When AI recommends your practice — when it names you, cites your content, and sends someone to your website — that person is dramatically more likely to become a patient. Because they did not just find a listing. They received a recommendation from a system they trust.
But here is the catch: 62% of AI Overview citations go to sources that are NOT ranking on page one of traditional search. SEO ranking and AI citation are separate outcomes. Being good at one does not guarantee the other. You need a different strategy for each.
AI as the new front door
OpenAI launched ChatGPT Health in January 2026 — a dedicated medical search experience. Anthropic followed with healthcare-specific features shortly after. People are not just searching for health information on these platforms. They are asking:
"Who is the best dermatologist in Phoenix for adult acne?"
"My kid has a fever and a rash — should I go to urgent care or the ER?"
"Recommend a therapist in Denver who takes Blue Cross and specializes in anxiety."
These are the same questions they used to type into Google. Now they are asking AI directly. And AI is answering — with specific recommendations, based on the structured data, reviews, and authoritative content it can find.
If your practice has none of those things, you are not in the conversation.
What most practice websites look like — and why they fail
The typical medical practice website has:
- A homepage with a stock photo of smiling doctors
- A list of services with one-paragraph descriptions
- An "Our Team" page with headshots and credentials
- A contact page with a phone number and maybe an appointment request form
No structured data telling search engines or AI what specialties you cover, what insurance you accept, what conditions you treat, or what makes your approach different. No content answering the questions patients actually search for. No schema markup. No local optimization beyond a Google Business Profile that was set up three years ago and never updated.
This is not a website. It is a brochure — and it is invisible to every system that matters.
What optimized actually looks like for a medical practice
For traditional search (SEO):
- Dedicated pages for every condition you treat, every procedure you offer, and every location you serve
- Content that answers patient questions — "what to expect during," "how long does [procedure] take," "when should I see a doctor for [symptom]"
- Technical optimization — fast load times, mobile-friendly (25% of patients use voice assistants for healthcare searches), proper metadata
- Google Business Profile kept current — hours, services, insurance accepted, photos, regular posts
- A review strategy focused on volume and recency (500+ reviews at 4.3+ stars outperforms 50 reviews at 5 stars)
For AI search (GEO):
- Physician Schema with NPI numbers, board certifications, insurance networks, and languages spoken
- MedicalOrganization Schema with locations, services, telehealth capabilities
- Content structured for AI citation — clear claims, supporting evidence, medical review attribution
- Author bios with credentials and reviewer badges so AI systems can verify authority
- Presence across the platforms AI pulls from — Healthgrades, Zocdoc, Vitals, Doximity, local health publications
The key insight: GEO methods can boost your visibility in AI-generated responses by up to 40%. And the leads that come from AI citations convert at 13x the rate of traditional search. This is not a marginal improvement — it is a fundamentally better channel.
The bottom line
Two hundred and thirty million people ask AI health questions every week. 2.7 million search for urgent care near them every month. 1.2 million search for a dentist. Hundreds of thousands search for every other specialty.
Eighty-eight percent of those Google searches now show AI-generated answers. Eighty-three percent of those searches end without a single click. And when AI does send someone to a practice, that lead converts at 13 times the rate of a traditional search click.
The practices that optimize for AI visibility now — with structured data, authoritative content, and a presence across the platforms AI trusts — will capture patients at rates their competitors cannot match. Everyone else will keep paying rising CPCs for declining returns while their potential patients get their answers from AI that has never heard of them.
The shift is not coming. It is here. The only question is whether your practice is part of the answer.
