Health advertising rules for clinic website copy (US, UK, Australia, Canada)

Clinic owners often ask us to "make the website more persuasive". In healthcare, persuasive has limits. Regulators in every major English-speaking market restrict what health businesses can say in their advertising, and your website counts as advertising. This guide gives you a practical overview of those limits and how to write copy that's compelling and compliant. It's general information, not legal advice; rules change, and your professional body or insurer is the best place to check specifics.

The shared principles

Despite different laws, the regulators agree on a few things:

Be truthful. Don't say anything you can't back up.
Have evidence for health claims. If you say a treatment helps a condition, you need appropriate evidence, not just patient anecdotes.
Don't create unreasonable expectations. Avoid guarantees, "permanent" results or "no risk".
Don't exploit vulnerability. No pressure tactics or fear-based messaging.
Be clear about price and conditions when you advertise offers.

United States

The Federal Trade Commission requires health-related advertising claims to be truthful, not misleading, and supported by competent and reliable scientific evidence. Its Health Products Compliance Guidance explains what that means in practice. The FTC's Endorsement Guides cover testimonials and reviews: they must reflect honest experiences, and if a testimonial describes results that aren't typical, that matters. State medical, dental and chiropractic boards may add their own rules, for example on using "specialist" titles. If you collect health information online, HIPAA may apply to the forms and tools you use.

United Kingdom

The UK Code of Non-broadcast Advertising (CAP Code), enforced by the Advertising Standards Authority, applies to claims on your own website. Medical and health claims need robust evidence. Prescription-only medicines, including botulinum toxin, can't be advertised to the public. The ASA publishes topic-specific advice, for example on botox and prescription-only medicines. Regulated professionals (GDC, GMC, HCPC, GCC) also have their own standards on advertising and on describing qualifications.

Australia

Registered health practitioners must follow advertising rules under the National Law, with guidance from AHPRA and the national boards on its advertising hub. Key points include no false or misleading claims, no offers without clear terms, no creating unreasonable expectations of benefit, and no testimonials about clinical aspects of care. Prescription medicines can't be advertised to the public under rules administered by the TGA. AHPRA has also issued specific guidance for practitioners offering non-surgical cosmetic procedures.

Canada

The Competition Act prohibits false or misleading representations, and the Competition Bureau enforces it. Provincial regulatory colleges (for dentists, physicians, chiropractors, physiotherapists) set their own advertising standards, often including limits on testimonials and comparative claims. Health Canada regulates advertising of drugs and medical devices. Check your college's advertising standard.

Words and phrases to avoid

Risky	Safer alternative
"Guaranteed results"	"We'll explain the realistic results at your consultation"
"Painless"	"We'll talk you through comfort options, including numbing"
"Permanent"	"Long-lasting for many patients; we'll discuss how long results typically last"
"Cures back pain"	"Assessment and treatment for lower back pain"
"The best dentist in town"	"A family dental practice in [town] since [year]"
"Botox from $9 a unit" (UK/AU)	"Anti-wrinkle consultations with a registered prescriber"
"Specialist" (without the registered title)	"Special interest in…" (check your board's rules)

Testimonials, reviews and before/after photos

Testimonials: restricted for clinical care in Australia and by many Canadian colleges. In the US and UK they must be genuine and not misleading. Linking to your independent Google reviews is generally a safer option than republishing selected quotes, but check your local rules.
Before/after photos: need written patient consent, must be unedited and representative, and should explain that results vary. Some regulators restrict them for certain treatments.
Never write fake reviews or offer incentives for reviews.

Offers and discounts

Time-limited offers, free consultations and gift vouchers are generally allowed if the terms are clear and the offer doesn't pressure people into treatment. In Australia, AHPRA guidance says offers must state their terms and conditions. Avoid "today only" urgency for medical procedures.

Qualifications and titles

State qualifications accurately, use protected titles only if you hold them, and keep registration details current. If the person performing a treatment isn't a doctor, don't imply that they are.

A simple process for compliant copy

Write the page in plain English, describing the service and process.
Highlight every claim about outcomes, safety or comparisons.
For each, ask: do we have evidence? Would a patient read this as a promise?
Remove or soften anything you can't support.
For high-risk treatments, have the page reviewed by your professional body, indemnity insurer or a lawyer.
Re-check annually, as guidance changes.

Social media and ads count too

The same rules generally apply to your social media posts, paid ads, email newsletters and Google Business Profile posts, not just your website. A claim you've carefully removed from a treatment page can easily reappear in an Instagram caption or a promotional email. Keep a short "approved phrases" document for your team and anyone who writes content for you, and make sure ad landing pages say the same as the ad. Platforms also have their own health advertising policies, which can be stricter than the law in some areas, so ads for certain treatments may be rejected even if your copy is compliant.

How we approach it

When we build clinic, med spa and chiro and physio websites, we write factual service descriptions by default, flag claims we think are risky, and leave testimonials and before/after galleries out unless you confirm they're permitted for you. The final sign-off is always yours, because you know your regulator best.
