Use cost per lead as the first question, not the final answer
Dentists often search for cost per lead because it feels concrete. The better question is whether that lead can be reached, qualifies for the treatment, books a consult, shows up, and has enough case value to support the acquisition cost.
How to compare channels without fooling yourself
Google Ads, SEO, Meta Ads, and local visibility all create different kinds of demand. A channel with a higher front-end cost can still win if the patient intent, show rate, and treatment acceptance are stronger.
What should be excluded from ROI
Raw clicks, junk forms, unreachable leads, duplicate submissions, and consults that never show should not be counted as ROI. They are useful diagnostic signals, but not production.
Why 20x+ average ROI can still require caveats
Booked.Dental uses 20x+ as the average proof story across strong-fit clinics, but individual results depend on treatment value, response speed, local demand, case acceptance, and whether rejected-lead feedback is used.
Channel benchmark lens
| Channel | Best use | Primary risk | Quality signal |
|---|
| Google Ads | Capture active treatment searches | Expensive weak-fit clicks | Booked consult cost |
| Meta Ads | Create demand with proof-led creative | Cheap but low-intent volume | Qualified opportunity rate |
| SEO | Compound local and treatment visibility | Slow feedback loop | Organic market checks |
| Landing pages | Convert existing demand | Generic page mismatch | Form-to-qualified rate |
| Follow-up | Recover serious inquiries | Slow first response | Reachable-to-booked rate |
