The Compliance Tightrope
Selling supplements on Google Ads is like walking a tightrope in a windstorm. One wrong claim and your ads get disapproved. Too cautious and your copy is so bland nobody clicks.
Google's healthcare and medicines advertising policies are among the most strictly enforced. For supplement brands, understanding the boundaries is not optional. It is existential.
What Google Will Not Allow
Google prohibits ads that make specific health claims about supplements. This includes:
- Claims that a product treats, cures, or prevents a disease
- Before-and-after comparisons implying medical outcomes
- References to clinical studies without proper substantiation
- Testimonials that imply guaranteed health results
The enforcement is algorithmic and aggressive. One flagged ad can trigger a manual review of your entire account. Multiple violations can lead to account suspension.
The Grey Area That Gets Brands Suspended
The most dangerous zone is "implied health claims." These are statements that do not explicitly claim medical benefits but strongly suggest them:
- "Supports immune function" (borderline, often approved)
- "Boosts your immune system" (likely disapproved)
- "Helps fight colds" (almost certainly disapproved)
The line between "supports" and "boosts" can be the difference between a running campaign and a suspended account.
Feed-Level Compliance
Your Shopping feed is where most supplement brands get caught. Product titles and descriptions pulled directly from your website often contain claims that pass on Amazon but fail on Google.
Common feed violations:
- Product titles including "fat burner," "detox," or "anti-ageing"
- Descriptions referencing specific health outcomes
- Images showing before-and-after transformations
- Custom labels that reference medical conditions
How to Build a Compliant, High-Performing Account
1. Audit every product title and description
Strip medical and health claims from your feed. Focus on ingredients, format (capsules, powder, liquid), and lifestyle positioning rather than outcomes.
2. Use structure claims, not outcome claims
EU and UK regulations allow "structure/function" claims that have been authorised. "Vitamin C contributes to the normal function of the immune system" is an authorised EFSA claim. "Vitamin C prevents colds" is not.
3. Separate campaigns by compliance risk
Run your safest products (vitamins, minerals with approved claims) in broad campaigns. Keep higher-risk products (weight management, sports nutrition) in tightly controlled campaigns with manually reviewed ad copy.
4. Build a pre-approval checklist
Before any ad goes live, check:
- Does the headline contain a health claim?
- Does the description reference a medical condition?
- Does the landing page make claims the ad does not?
- Are all claims backed by authorised sources?
5. Monitor disapprovals daily
Do not wait for your monthly agency report. A single disapproval can cascade. Check the policy manager daily and address issues within 24 hours.
The Subscription Angle
Most supplement brands rely on repeat purchases. Your Google Ads strategy should reflect this. The first sale is an acquisition cost. The value is in months two through twelve.
This means your CPA targets for new customers should be higher than your single-order margin suggests, but only if you have the data to prove your subscription retention rate.
If your agency is optimising for first-order ROAS on supplements, they are optimising for the wrong metric.
