THE SHORT ANSWER
CTR measures clicks relative to impressions. A conversion measures a configured action. Neither automatically means a new patient. Useful reporting distinguishes attention, inquiries, bookings, and attended visits—and names the gaps between them.
What is CTR—and what does it leave out?
Click-through rate is clicks divided by impressions, expressed as a percentage. If an ad receives 120 clicks from 4,000 impressions, its CTR is 3%. It describes the step from seeing an ad to clicking it. It does not tell you whether the person contacted the practice, qualified for a service, or attended an appointment.
Source: Google Ads: Clickthrough rate ↗A branded search campaign and a broad awareness campaign reach people with different levels of familiarity and intent. Compare like with like before deciding that a higher CTR means a stronger campaign. A message can become more clickable while becoming less accurate about the service. That is not the improvement a practice needs.
What does the report call a conversion?
In Google Ads, conversion rate relates recorded conversions to eligible ad interactions. The configured actions and counting rules matter; multiple counted actions can produce more than one conversion per interaction. Ask what is included before comparing percentages.
Source: Google Ads: Conversion rate ↗For a practice, a phone-button click, a connected call, a submitted form, a booked consultation, and an attended visit are different events. A report should name them plainly. If “conversions” includes both an inquiry and a page view, the combined total is difficult to use for staffing or budgeting decisions.
Begin with a measurement agreement: which event is being counted, whether repeat events are deduplicated, what date is used, and which system supplies the outcome. Do not label a button click as a patient.
A lower CTR can still produce a better result
Illustrative example—not Everest client results or an industry benchmark. Both campaigns use the same measurement definitions.
Campaign A: 10,000 impressions → 500 clicks → 25 inquiries → 5 attended new-patient visits. Ad spend: $1,000.
Campaign B: 10,000 impressions → 300 clicks → 30 inquiries → 10 attended new-patient visits. Ad spend: $1,000.
A has a 5% CTR and B has a 3% CTR. Yet B produces twice as many attended visits in this example. A’s ad-spend-only cost per attended new patient is $200; B’s is $100. Judging the campaigns only by CTR would favor the wrong outcome for this particular goal.
The example does not prove that lower CTR is desirable. It shows why the metric must be interpreted with the rest of the journey. Before reallocating spend, check whether the services, geography, attribution window, and appointment maturity are comparable.
Which costs belong in the calculation?
Use a label that matches the numerator. Ad spend divided by attributed new patients is an ad-spend-only acquisition measure. A broader acquisition calculation can include agreed marketing fees and other acquisition costs. Those two figures should not be presented as interchangeable.
Everest’s management fee and advertising spend are separate. The practice pays the ad platforms using its own payment method. A useful budget conversation therefore considers the service fee, platform spend, and any separately scoped work, as well as the practice’s capacity to handle demand.
Revenue is not profit, and an assumed patient lifetime value is not collected revenue. If a projection uses repeat visits or treatment acceptance, show those assumptions. A conservative scenario can be more useful than an attractive return estimate built on unverified inputs.
Find the stage that is losing people
- Views but few relevant clicks: examine intent, targeting, and whether the message fits the service.
- Clicks but few inquiries: inspect the page, service fit, device experience, and contact path.
- Inquiries but few bookings: check response handling, availability, eligibility, and the reason for contact.
- Bookings but few attended visits: review cancellations, scheduling delays, and follow-up with the practice team.
These are starting questions, not diagnoses from a chart. Broken tracking can resemble poor performance. A campaign that attracts existing patients may produce useful calls without meeting a new-patient goal. Keep the operational context next to the numbers.
What a useful monthly review should answer
What changed? Which services and locations drove it? Are the numbers comparable with the previous period? What evidence supports the next action? What is missing from the data? A report that answers these questions can guide decisions without pretending to capture every interaction.
When appointment outcomes are unavailable, say so. Report verified inquiries and document the gap rather than estimating patient counts from clicks. When collecting outcome information, use an appropriately designed workflow rather than placing patient details into advertising URLs or general-purpose analytics.
WORKED EXAMPLE / A MONTHLY REVIEW
Turn a report into a decision
Illustrative figures only—not client results or a benchmark. Assume the same service, reporting window and attribution rules in both months.
| Measure | Month 1 | Month 2 | Question to ask |
|---|---|---|---|
| Ad spend | $1,000 | $1,000 | Was the budget and campaign scope comparable? |
| Inquiries | 25 | 30 | Did the definition, quality or duplicate handling change? |
| Booked visits | 10 | 10 | Why did more inquiries not become more bookings? |
| Attended new-patient visits | 8 | Unknown | Is the second month mature enough, and is attendance data available? |
The next action: inspect inquiry handling, appointment availability and measurement before increasing spend. The example shows more inquiries at the same cost, but it does not establish more attended visits or a better financial return.
Month 1’s ad-spend-only cost per attended new patient is $125. Month 2 cannot support the same calculation until the outcome is known. Management fees are separate and should be included if the agreed metric is total acquisition cost.
