In functional medicine marketing the sale is a program that runs for months, so a form fill proves little: count discovery calls held and programs paid per channel. Before you pay for any click, check each service you advertise against Google's healthcare policy and the FTC's evidence rules.
Quick answer
- Count three things per channel: discovery calls booked, calls held, programs paid.
- Read Google's healthcare policy against each service you plan to advertise.
- Cut any line that says a program treats, reverses or cures a disease unless you hold competent and reliable scientific evidence for it.
- Ask your accountant what an HSA can pay before you print "HSA eligible."
- Divide ad spend by enrollments. Ignore cost per form fill.
From click to second payment
Write down how many people reach each row, from the click to the second payment.
| Step | Where it lives | Who can lose it |
|---|---|---|
| Click or call | Ad platform | Wrong keyword or audience |
| Discovery call booked | Calendar | A form with too many fields |
| Call held | Calendar | No reminder, wrong time zone |
| Enrolled | Your payment tool | A price talk the call didn't prepare |
| Paid in month two | Your payment tool | Weak onboarding |
On their own, ad platforms see only the first row. Your calendar and payment tool see the rest, so the other four counts must come from you.
Give each channel its own booking link and ask every caller on the discovery call where they found you. A tag on the link and one question on the call are enough to start. Patient acquisition strategy shows how to cap this against what your schedule can hold.
What Google, the FTC and Meta allow
Google first. Its healthcare policy says it doesn't allow "speculative and/or experimental medical treatments". It also bans products that "imply they're as effective as prescription drugs or controlled substances."
An unproven protocol, or supplements pitched as working like a prescription, falls on the wrong side of those lines. Google Ads healthcare policy walks through the strikes and appeals.
Telehealth that can end in a prescription is a separate gate. Google's prescription drug services rules cover telemedicine providers, and in the US and Canada it wants LegitScript accreditation plus its own certification. The page doesn't say how it treats video visits that never prescribe, so ask Google Ads support.
Then the FTC. Its Health Products Compliance Guidance wants "competent and reliable scientific evidence" for health claims, which as a general matter means randomized, controlled human trials. Patients who got better in your own clinic don't meet that bar: the guidance calls what a practitioner sees in patients anecdotal.
Meta has its own health and wellness standard. Facebook ads for doctors covers it. Weight loss and GLP-1 programs are in GLP-1 advertising.
In Canada, the Competition Bureau tells advertisers to make performance claims only if an adequate and proper test supports them. A court can find an ad misleading even when no one was actually deceived.
What a first test looks like in each channel
Pick one row to test first.
| Channel | Setup for a first test | The count that matters | Policy risk to check first |
|---|---|---|---|
| Google search ads | One landing page, one booking link, a phone number used only here | Programs paid from calls on that number | Experimental treatment wording on the page |
| Meta ads | One ad, one booking page | Programs paid, by the where-did-you-find-us question on the discovery call | Copy that implies you know the reader's condition |
| Webinar | Registration page, a reminder email, a booking link at the end | Discovery calls booked from attendees | Outcome claims on slides |
| Podcast or guest spot | A page and phone number only for that show | Programs paid from that page | Claims you make live, unedited |
| Agency retainer | The ad account in your name, with admin access | Programs paid, reported weekly | Who writes the health claims |
Two promises that don't belong in an ad
Don't promise care in every state, and don't promise HSA payment.
On licensure, the Medical Board of California says physicians giving telehealth care to patients in California must be licensed in California. Each US state board sets its own rules, so a national telehealth ad needs a list of states where each clinician holds a license. Put that list on the page.
On payment, HSAs are a US account, and their money pays only for medical care as the tax code defines it. IRS Publication 502 leaves out expenses "merely beneficial to general health."
Supplements count only when a practitioner recommends them for a specific condition a physician diagnosed. A weight-loss program counts only as treatment for a diagnosed disease, never for "general health, or sense of well-being." This is not tax advice, and I'm not an accountant.
The notice also leaves out lab services not typical of a primary care office. So a monthly membership that bundles specialty lab panels or prescriptions, or is led by a naturopath or chiropractor, may fall outside that rule. Ask an accountant before the word "HSA" goes on your site.
An imaginary six-month program, two channels
Look at your own search results today
On your phone, open a private browser tab and search your main service plus your city. Note whether ads appear and who runs them. Then open Google's healthcare policy page and read the section for your top service.
Last, open your own program page and highlight every sentence that says what the program does to a disease. Each highlighted claim needs competent and reliable scientific evidence behind it, the FTC standard above, or it comes out.
What to ask a functional medicine marketing agency
- Whose name is on the ad account, and do I get admin access?
- What counts as a lead in your report?
- Do you report enrollments and payments, or only calls and forms?
- Who writes health claims, and which evidence do they check against?
- Can I see ad copy before it runs?
If the report stops at calls and forms, you count enrollments yourself. Facebook ads for doctors has more vendor questions for Meta.

Frequently asked questions
Can a functional medicine practice run Google Ads?
Yes, for services Google doesn't treat as speculative or experimental, which its healthcare policy bars. Telehealth that can end in a prescription is a separate gate: in the US and Canada, Google wants LegitScript accreditation plus its own certification. Read the healthcare page against each service before you pay for a click.
Can I advertise telehealth visits to patients in every state?
Only in the states where the clinician holds a license. The Medical Board of California, for one, says physicians treating patients located in California by telehealth must be licensed in California. Put the list of states for each clinician on the booking page.
Can patients pay for my program with an HSA or FSA?
Sometimes, but not because you are a health practice. HSA money pays for medical care as the tax code defines it, and IRS Publication 502 leaves out costs 'merely beneficial to general health,' so the answer turns on a condition a physician diagnosed. Ask the patient's plan administrator, not your ad.
What is a lead worth in a six-month program?
A form fill is worth nothing until it turns into a held discovery call and then an enrollment. Divide ad spend by enrollments, not by form fills, and compare channels on that number.
Does a Canadian practice follow different advertising rules?
Yes. Canada's Competition Act applies, and the Competition Bureau says to make performance claims only if an adequate and proper test backs them. Provincial colleges add their own rules for advertising by regulated health professionals.
