Frequently asked questions from therapeutic practices

What am I allowed to advertise under the German healthcare advertising law (HWG)?

The HWG (Heilmittelwerbegesetz) allows factual information about your services, methods and practice. Forbidden are cure promises („cures migraine“, „guaranteed pain relief“), success rates („85 % of patients“), comparative efficacy claims and before/after depictions without factual context. In practice this means in ads: method name instead of effect promise, neutral description instead of emotional pressure. We write every ad HWG-compliant and document the legal rationale per asset.

Does SEA pay off if I'm fully booked as a statutory-insurance therapist?

For a pure statutory-insurance practice rarely — patients facing a 3–9 month waiting list find their therapist through the official referral service or their own initiative. Ads fill a slot that would fill anyway. SEA pays off for self-pay services: couples therapy, coaching-style offerings, self-pay sessions billed via the fee schedule, IGeL services, sports physiotherapy, manual therapy. There, competition is higher and visibility — not capacity — is the bottleneck.

How do you track conversions without client data flowing into the cloud?

Server-side tracking instead of browser GTM: form submits run through your own server, only an anonymous conversion event with click ID (GCLID) goes to Google Ads — no names, no diagnoses, no phone numbers. Client data stays in your practice software. For Doctolib or jameda bookings we measure the click-to-booking conversion via the platform interface. Conversion events are processed with anonymized IP and without remarketing lists.

What about waiting times for statutory-insurance patients — doesn't that distort expectations?

If you only have statutory-insurance slots: yes, then advertising is in most cases pointless and even misleading, because searchers expect „appointment within 2 weeks“. In that case we recommend: no SEA campaign, but clean local visibility via Google Business Profile. If you offer self-pay appointments or free slots, we make availability transparent in the ad („self-pay appointments available short-term“, not „appointment guaranteed today“). Wrong expectations are ethically off-limits and cost trust a practice can't regain.

What can go in the ad — and what cannot?

Allowed: method name (behavioral therapy, depth psychology, manual therapy, medical training therapy), area of practice (couples therapy, anxiety disorders, back complaints), location, self-pay note, appointment booking. Not allowed: efficacy promises („we resolve your anxiety“), comparisons („best therapy in Cologne“), success rates, treatment of unrecognized indications with efficacy claims (particularly strict for non-medical practitioners). Ethically also off-limits: fear amplification („Burnout? We'll fix you“) — legally borderline, brand-damaging, client-damaging.

What are typical CPCs for therapy searches?

Psychotherapy + city typically costs 2–6 € per click, couples therapy + city 3–8 €, physiotherapy + city 1–4 €. With self-pay sessions at 90–180 €, these CPCs pay off even at a 3–6 % landing page conversion rate — one won client covers 20–40 ad clicks. Important: tight targeting (15–25 km radius), build negative keywords against „study“, „training“, „course“, „free“, „DIY“, otherwise you get learners instead of clients.
