Frequently asked questions from dental practices

What am I actually allowed to advertise under HWG?

Factual information about services is permitted, for example 'implantology with over 15 years of experience' or 'digital aligner treatment'. Forbidden are before/after pictures without a clear disclaimer, success guarantees, comparative advertising ('best practice'), exaggerated prices and promoting cures. We write every ad and landing page to withstand German healthcare advertising law (HWG), professional rules and unfair-competition law — before/after pictures belong in a patient-only area, not in ads.

How many implant inquiries are realistic?

In a mid-sized German city, 8–20 qualified implant inquiries per month at a budget of 2,500–5,000 € are realistic. Landing-page conversion rate sits at 4–9%, click-to-appointment rate at 30–55%. The range depends heavily on location, competitive density, review profile and the consultation process in the practice.

What does a new patient cost — and what does an implant patient cost?

For classic services (cleaning, check-up) we land at 30–60 € per new patient. For implant inquiries 60–150 € CPA is realistic, for Invisalign 50–120 €. Sounds high — but an implant patient generates 3,000–15,000 € of treatment revenue, an Invisalign patient 3,000–7,500 €. Lead CPAs up to 200 € pay off easily for self-pay services.

How do we track without sending patient data to Google?

Patient data may not land in GA4 or Google Ads — that would breach both medical confidentiality and GDPR. We set up server-side tracking: the landing page only fires an anonymous conversion signal ('appointment click', 'call 60s+'), the actual patient contact runs separately through your practice system (Doctolib, jameda, practice software). Google only sees that a conversion happened — never who.

Should I use Performance Max or classic search campaigns?

For dental practices we recommend classic search campaigns. Performance Max automatically mixes images, headlines and descriptions from the asset pool — and may combine statements or images that are problematic under HWG. With classic search you see every combination beforehand and can approve it for legal safety.

Our practice is already full — why run Google Ads?

Full is not the same as profitable. A full practice with a high statutory-insurance share earns significantly less per treatment hour than one with a deliberately built self-pay base. Google Ads here is not a volume lever, it is a selection lever: more implant, Invisalign and veneer inquiries, fewer cleaning-volume callers. Shift the mix instead of stuffing the schedule.
