Most clinic marketing reports are built to be shown rather than used. They lead with the numbers that always go up, and they stop short of the ones that decide whether the spending was worth it.
Here is the short list to insist on, and none of it requires a new system, only somebody to write things down.
How many people asked, and on which channel
This is the count of real enquiries, split by WhatsApp, Instagram, the website form and missed calls. It is not impressions or reach, but the number of people who asked a question.
This is missing more often than any other line, because nobody owns the count. The agency counts what the platform reports and the clinic counts what reached the front desk. The two numbers are never the same, and the gap is the interesting part.
How many got a reply, and how long they waited
Ask for two figures rather than one: the percentage that got any reply at all, and the distribution of how long they waited. Ask for the distribution, not the average. An average hides the tail, and the tail is where the money goes.
How many were a real fit, and on what basis
Not every enquiry is a patient, because some are price shoppers, some want a treatment you do not offer, and some are in another city. A report that treats all enquiries as equal will tell you your marketing is working while your calendar stays empty.
The important half of this line is the basis, because whoever qualified the enquiry should be using rules you wrote and not their own judgement.
How many booked, and how many turned up
These are 2 different numbers and reports routinely publish only the first, because the first is larger.
A booking that does not turn up costs you the same empty chair as no booking at all, plus the time spent making it. If your report stops at bookings, it stops one line before the line that matters.
How many were won back after a missed appointment
Somebody who booked and did not arrive has already decided they want the treatment, so they are the warmest contact in your database. In most clinics, nobody calls them.
How many were lost, and why
This is the line that never appears, even though every clinic loses enquiries. A report that shows no losses is not a report of a perfect month, it is a report that is not counting.
A report you cannot trust when the numbers are bad is worthless when they are good.
The test is simple: ask whoever produces your report to show you last month's worst number and the reason behind it. If that does not exist, you are not being reported to, you are being presented to.
