Every regulator writes its own rules, but a few sentence patterns break all of them at once. Learn these five and you avoid most of the risk before you ever open a rulebook.
Key takeaways
- Regulators differ enormously in detail but converge on the same five prohibited patterns.
- The riskiest sentences are enthusiastic rather than dishonest, which is exactly why they survive internal review.
- Rewriting for compliance almost always improves the writing, because it forces specificity.
Health regulators do not agree on much. The dental, massage, chiropractic, physiotherapy, and medical aesthetics rulebooks differ on testimonials, on before-and-after imagery, on what counts as a comparative claim, and on how much of it applies to social media.
But they converge almost completely on five sentence patterns. Learn these and you avoid most of your exposure without reading a single rulebook — then go and read your own, because the details are where the remaining risk lives.
Nobody sets out to write non-compliant marketing. The sentences that cause problems are rarely dishonest — they are enthusiastic, written quickly, and they read fine to whoever wrote them. That is precisely why they survive internal review and sit on a website for two years before anyone notices.
1. Superiority claims
Flagged: "the best dentist in London", "the leading physiotherapy clinic in the region", "superior results".
Most health regulators restrict comparative and superlative claims because they cannot be substantiated and they disparage colleagues by implication. This is the single most common flag, and it is usually written without a thought.
Instead: describe what is specifically true. "One of the few clinics in the area offering same-day crowns" is a factual, checkable statement that does more work than "the best" ever did.
2. Outcome guarantees
Flagged: "eliminate your back pain", "guaranteed results", "we will fix your posture".
Promising a clinical outcome is a problem in nearly every jurisdiction, and it is a problem in general advertising law too.
Instead: describe the process rather than the result. "We start with a full assessment and build a plan around what we find" promises something you can actually deliver, and it is more reassuring to a sceptical patient than a promise they do not believe.
3. Testimonial-shaped content
Flagged: patient stories, quotes about results, before-and-after sequences used as evidence.
Several regulated professions restrict testimonials specifically, and the restrictions are often stricter than practitioners realise — including for content that is not labelled as a testimonial but functions as one.
Instead: educational content that answers the question the testimonial was there to reassure about. Someone who reads a clear explanation of what recovery actually involves is reassured more durably than by a stranger's quote.
Every one of these rewrites makes the sentence more specific. That is not a coincidence. Vague enthusiasm is what the rules are aimed at.
4. Borrowed authority
Flagged: "research proves", "clinically proven", "studies show" attached to a claim with no study behind it.
Instead: "current evidence suggests", or better, name what you are referring to. If there is no source, the sentence should not carry the weight of one.
5. Scope drift
Flagged: claims that stray outside what your profession is licensed to do — a massage clinic implying diagnosis, a chiropractor implying treatment of a systemic condition.
This is the one that most often arrives via a marketing agency that does not know the profession, and it is the one regulators take least kindly to.
Why this makes the writing better
Every rewrite above replaces a vague claim with a specific one. "The best clinic" becomes a fact about your equipment. "Eliminate your pain" becomes a description of how you work. "Research proves" becomes an honest characterisation of the evidence.
Specific writing converts better, because patients have read a thousand websites claiming to be the best and none of them believed any of it. Compliance is not the tax on good marketing here. It is largely a description of it.
Then read your own rulebook
These five are the floor, not the ceiling. Beyond them the professions diverge sharply, and the divergence is where most actual complaints originate — massage therapy in Ontario bars reposting client reviews entirely, which surprises people coming from other fields; medical aesthetics carries obligations around off-label use that no other profession shares.
We keep a plain-language summary of the Ontario rules for each profession:
- Dental advertising rules
- Massage therapy advertising rules
- Chiropractic advertising rules
- Physiotherapy advertising rules
- Med spa advertising rules
