OB-GYN Marketing: Two Patient Paths, One Privacy Line

OB-GYN marketing has to run two patient paths at once, not one funnel. An obstetric patient usually picks the practice early in pregnancy and brings many visits over many months; a gynecology patient often books one visit and may or may not come back. Either way, reproductive health data is among the most sensitive an ad platform can be handed.

Quick answer

Count new OB intakes and new gynecology patients separately, by source, inside your scheduling system, not inside an ad account. Keep every page that names pregnancy, fertility, contraception or abortion care free of a tracking pixel, and never let a visit reason reach a call tracking service, a form tool or an ad platform. Give each ad its own landing page and, if volume justifies it, its own phone number, so a booking can be counted without saying what it was for.

How do an OB patient and a gyn patient reach you differently?

An OB patient's first call to your office is usually the only acquisition decision she makes for the practice. Everything after it is a scheduled visit inside a pregnancy that is already underway, and the physician's hospital privileges (which delivery hospitals a provider is approved to admit and treat patients at) decide where she can give birth. A gynecology patient makes that decision every time: an annual exam, an IUD insertion, a menopause consult, each one a fresh choice of where to go.

Make the intake form's "how did you hear about us" field required for both paths, with fixed choices, so every new patient carries a source next to her visit type and a source that only fills annual exams never gets credit for OB intakes. Patient scheduling software covers what else that system should capture at booking.

What makes reproductive health data riskier than other patient data?

This part is not legal advice, and I am not a lawyer. HHS's Office for Civil Rights issued a bulletin on tracking technologies on websites and apps, and a Texas federal court later vacated the part of it that said HIPAA obligations are triggered when an online tool connects a visitor's IP address with a visit to an unauthenticated public page about specific health conditions or providers; HHS says it is evaluating next steps in light of that order (HHS, checked 2026-10-09). The bulletin still says that a tracking tool on a public booking page that collects a visitor's email address or typed reason for the visit is collecting protected health information.

Separately, HHS issued a final rule in April 2024 prohibiting, in certain circumstances, the disclosure of protected health information related to lawful reproductive care. HHS now says the federal court for the Northern District of Texas vacated most of that rule on June 18, 2025, in Purl v. HHS; the changes to the Notice of Privacy Practices (the privacy notice you give patients) that the court did not strike remain in effect, and HHS says it will determine next steps after reviewing the decision (HHS, checked 2026-10-09). Have whoever handles HIPAA for your practice confirm where that leaves your own notice and policies.

Two FTC actions show why an ad platform is the wrong place for any of this, rule or no rule. The FTC alleged that Flo Health, after promising to keep users' health data private, disclosed health data from its period and ovulation app, including the fact of a user's pregnancy, to marketing and analytics providers such as Facebook's and Google's analytics divisions (FTC, checked 2026-10-09). It alleged that Easy Healthcare, which runs the Premom fertility app, disclosed sensitive health data to AppsFlyer and Google and shared health information for advertising without users' affirmative express consent, despite privacy policies promising not to share it without consent (FTC, checked 2026-10-09).

Washington's Attorney General calls the state's My Health My Data Act the first privacy-focused law in the country to protect personal health data that falls outside HIPAA; information identifying a consumer's past, present or future physical or mental health status is "consumer health data" under it. Its sections 4 through 9 have applied since March 31, 2024, and since June 30, 2024, for small businesses (Washington State Attorney General, checked 2026-10-09). A Canadian OB-GYN practice answers to PIPEDA, the federal law on personal information handled in for-profit, commercial activities, or to a provincial law deemed substantially similar, such as Ontario's law on personal health information (Office of the Privacy Commissioner of Canada, checked 2026-10-09), never HIPAA.

Which pages and fields must never feed an ad pixel?

Anything that says why someone is booking. Keep a tracking tag off any page whose URL, title or heading names pregnancy, fertility, contraception or abortion care, and off the booking calendar and the intake form themselves, the pages where HHS's bulletin says a typed email or visit reason reaches a tracking vendor as protected health information. Name the counted result something neutral, such as "new patient booking," never "pregnancy inquiry" or "IUD consult." HIPAA-conscious conversion tracking lays out the schema-level version of this boundary: a table with no column a visit reason could land in.

Count the booking itself inside your scheduling system first. If you later send results to an ad account to improve bidding, send only consented, neutral conversions: a click identifier, a date and a yes-or-no outcome. Otherwise keep daily counts by source in your own report and send nothing; either way, no visit reason should exist in a system that reports to an ad platform.

How do Google's and Meta's health rules limit your targeting?

Google treats health as a sensitive interest category and gives "treatments for pregnancy and infertility" as one of its own examples, alongside invasive procedures such as surgery and injections (Google, checked 2026-10-09). Ads in that category cannot use advertiser-curated audiences: Customer Match (a list of your own patients you upload), your data segments (remarketing lists), audience expansion and lookalike segments. Google's predefined audiences stay available because sensitive signals are excluded from them automatically. Google lists birth control as its own sensitive interest category next to health, so contraception ads face the same audience limits (Google, checked 2026-10-09); Google's healthcare ad policy covers the rest.

Meta works differently: it may assign a category to a whole data source, such as your website or app, and "health and wellness" covers a source that "is associated with medical conditions or specific health statuses, provider/patient relationships" (Meta, checked 2026-10-09). Meta's page lists health and wellness among the categories that may carry additional data sharing restrictions. A site built around OB-GYN care is a plausible candidate, so check the category in Events Manager rather than assume it; if you think a category Meta assigned is wrong, the page says you can ask Meta to review it again.

What should you ask a marketing vendor before they touch your ad account?

• Which patient path, OB or gyn, does each campaign target, and does the reporting keep the two separate?
• Which of my pages carry a tracking pixel, and does any of them name pregnancy, fertility, contraception or abortion care?
• What does the counted conversion get named in the ad account, and could that name describe a visit reason?
• If a call tracking service is involved, what does it pass to the ad platform beyond that a call happened?
• What data source category has Meta assigned my site, and have you checked it in Events Manager?

What is a new OB patient worth next to a new gyn patient?

Illustrative: the two-physician OB-GYN group below is invented for this example, and every figure in it, including the fees, is invented too; none of it comes from a client.

Value per OB patient = (average prenatal visits x average visit charge) + delivery professional fee: (10 x $145) + $2,450 = $1,450 + $2,450 = $3,900.

Value per gyn patient = annual exam charge + (average follow-up visits x average follow-up charge): $210 + (1.3 x $160) = $210 + $208 = $418.

Quarter value by path = new patients x value per patient: OB is 21 x $3,900 = $81,900; gyn is 75 x $418 = $31,350, for $113,250 together.

Gyn patients outnumber OB patients by more than three to one this quarter, yet the OB path is worth more than two and a half times as much. A channel that fills the calendar with gyn visits and one that fills it with OB intakes are not interchangeable even at the same cost per new patient, and no ad report will show you which is which; only the source field at intake and these two formulas will. Medical PPC works out the other side: what each new patient costs, from ad budget to visit.
