Google Ads cost for doctors has two parts: the ad spend itself (driven by cost-per-click, which varies by specialty and competition) and a management fee (a percentage of spend or a flat monthly fee). What matters more than either is cost per booked patient against patient value — the headline CPC is the least useful number.
The three numbers in an ad budget
- Cost per click: what you pay per visit, higher for competitive, high-value specialties
- Ad spend: clicks times CPC, set to gather enough data and fill capacity
- Management fee: a percentage of spend or flat retainer for running the account
Most practices fixate on CPC, which tells you almost nothing about whether ads are profitable.
Set spend by capacity and value
Don't pick a budget from a generic table — reverse-engineer it. Estimate how many bookable slots you need to fill, your historical click-to-booking rate, and your CPC, and back into the spend required. Cap it at the patients you can actually serve so you don't pay for demand you can't meet.
Watch cost per booked patient
A higher CPC in a high-value specialty can still produce a great cost per booked patient; a cheap CPC that never converts is pure waste. Judge the account on cost per booked patient versus patient lifetime value, and reallocate budget toward the keywords and landing pages that actually produce bookings.
A worked example
A specialist balked at a high cost per click and almost paused the account. But those expensive clicks were booking high-value procedures, so the cost per booked patient was comfortably below patient value. A neighbouring clinic with a far cheaper CPC was the one losing money, because its cheap clicks rarely booked. CPC had misled both.
Frequently asked questions
Is a percentage fee or flat fee better?
Percentage aligns the manager with scaling spend; a flat fee is predictable for steady budgets. Either is fine if reporting ties back to booked patients, not clicks.
What's the minimum viable budget?
Enough to collect statistically meaningful conversion data in your market. Too little spend can't learn, so the account never optimises out of its expensive early phase.
