You probably know that ChatGPT and AI search are among the best sources of new patients in 2026. Now there's another opportunity worth your attention: ChatGPT Ads.
Just like when you're not ranking on Google SEO yet, ChatGPT ads let you tap into the fastest growing source of new patients – while your organic ranking is still developing.
And right now, almost nobody in functional, integrative, hormone, or regenerative medicine is running them. That's the whole reason to read this now rather than in six months. Every ad platform before this one followed the same pattern. Google, Facebook, TikTok – early movers got returns that look absurd in hindsight, right up until everyone else arrived and bid the prices to where they sit today.
This guide covers what a local health practice needs to know before you spend anything, how the targeting works (it's nothing like Google), what to write, and what to honestly expect.
Three years ago, the entire conversation was about ranking on page one of Google. SEO, keywords, earning the click.
Yet over the past year, most clinics have watched 80-90% of that Google traffic disappear.
It didn't evaporate. It migrated.
Patients moved to AI search, and ChatGPT now holds roughly 70% of that market with Gemini making inroads given its integration with Google Chrome.
Here's why that migration matters more than the raw numbers suggest. Someone who starts her patient journey inside ChatGPT is about nine times more likely to convert into a discovery call than someone arriving from a Google click.
The reason is simple. By the time she types "who's the best BHRT clinic near me," she's spent hours reading about root causes, treatment approaches, and what testing involves — often using other practitioners' content. She arrives at that question already believing this kind of care might work. She just needs a name.
ChatGPT Ads is still officially in beta, and the formats are still changing. That's an argument for moving now, not for waiting.
Here's the part nobody in our space is talking about, and you should know it before you budget anything: ChatGPT ads serve only to Free and Go tier users. Plus, Pro, Business, Enterprise, and Education subscribers see zero ads.
Sit with what that means for a cash-pay practice.
If your ideal patient is a professional woman in her forties or fifties with disposable income and a habit of researching thoroughly – she's also exactly the sort of person who pays $20 a month for ChatGPT Plus. If she does, your ad will never reach her. Not once.
She can still find you inside ChatGPT – but only organically, through the answer itself rather than the sponsored card beneath it. Two conclusions follow from that:
Running ads to a site that AI can't read is how you burn your head start. Here's what to confirm first.
Two crawlers matter:
If either one is blocked, it fails silently. No error message, no warning in your dashboard. You simply don't show up, and nothing tells you why.
Practice websites are unusually vulnerable to this. The problem typically hides in one of three places: a security plugin like Wordfence or Sucuri, an SEO plugin that manages your robots.txt, or a firewall or CDN rule someone configured years ago and nobody has revisited.
None of those were set up maliciously. They were set up to block scrapers and bad actors, back when every unfamiliar bot was worth blocking. OpenAI's crawlers are newer than most of those rules.
The cost is real. A practice can spend six months building out FAQ content designed to get cited by ChatGPT, while a single line in a plugin config quietly prevents ChatGPT from ever reading a word of it. The same is true for letting crawlers analyze your Youtube content.
This one is worth checking today. If you'd like us to look, it's part of the free AI website assessment we run — we check crawler access along with the rest of your AI readiness and send you what we find.
Terms of service, a privacy policy, and your practice equivalent of a refund or cancellation policy all need to be published and reachable.
These are an eligibility requirement, not a nice-to-have. They're also missing or outdated on a surprising number of practice sites, usually because nobody has touched them since the site was built.
The landing page has to answer the question your ad implies, immediately, in the same words the ad used.
Someone who clicks an ad about hormone therapy should land on your hormone therapy page (or ideally on a dedicated hormone discovery call landing page) — not a general homepage where she has to hunt for the thing she was promised. Every extra step between the click and the answer is a place she leaves.
You cannot go back and attribute conversions for a campaign that ran without tracking. Whatever that first campaign teaches you is lost.
Two things to set up:
utm_source=chatgptso your own analytics can separate this traffic. OpenAI's reporting is aggregated at the campaign and ad level only.If you've run Google Ads, the structure will feel familiar with 3 levels: campaign, ad group, ad.
I recorded a 9-minute walkthrough covering the whole thing, from account creation through publishing your first ad:
A few mechanics worth knowing before you start:
This is the part that trips up anyone coming from Google ads, and it's the skill that separates campaigns that work from campaigns that waste money.
ChatGPT ads don't use keywords. Instead, each ad group gets context hints — a short, plain-language description of the kind of conversation where your practice belongs. ChatGPT matches on the meaning of the conversation rather than on exact phrases.
The formula that works:
Audience → intent (action verb) → topic → a constraint that filters out non-buyers
Weak version:
"People interested in hormone health."
Strong version:
"Women 45 to 60 in the Chicago area asking why they're exhausted, gaining weight, and sleeping badly despite normal thyroid labs — who are looking for a root-cause approach and are willing to invest in a structured program rather than a single appointment."
Notice what the strong version does. It names who, what they're actively doing, the specific topic, and a constraint that screens out people who'd never enroll anyway.
Two things that make yours better:
One more targeting note: ZIP-code targeting is now available for US campaigns, alongside country, region, and media market. For a practice trying to own a 20-mile radius rather than a state, that's the setting that matters.
The most common mistake with ChatGPT Ads is importing the voice that works somewhere else.
Google rewards keyword stuffing. Meta rewards a scroll-stopping hook. ChatGPT ads rewards the sentence a helpful expert would say next.
Hype language – like "revolutionary", "game-changing", "breakthrough" – reads jarring sitting next to a calm, measured ChatGPT answer, and it can actively lower your relevance score.
Which means practitioners have a genuine advantage here. The register that works is the one you already use across the desk from a patient.
Three rules for headlines:
The description's job is to add the one detail the headline left out. A qualifier, who this is and isn't for. Someone who reads it and self-disqualifies just saved you a paid click — and, more valuably, a wasted discovery call.
Finally, run five to eight genuinely different angles per ad group. Different by use case, audience, symptom, or outcome. Educational and comparison framing ("what to do when your thyroid labs come back normal") consistently outperforms discount framing in this environment.
Here's what most articles about ChatGPT ads won't tell you.
There are no verified benchmarks yet. OpenAI has published no official CPC, CPM, CTR, or ROAS figures. Every dollar number circulating online comes from agency blogs working off small samples, and they contradict each other.
We started running these campaigns for Big Boost a few weeks ago. What I can tell you is how to think about it:
If the infrastructure behind the click isn't there – a site that builds trust, a clear next step, follow-up that continues past the first email – these ads will find you highly qualified patients and then lose them. Acquiring the lead is the expensive part. Losing it afterward is the expensive mistake.
The sequence that makes sense for most practices:
The window on this is open now, in a space where almost nobody has noticed. That won't hold.
