How to measure conversion from inquiries to appointments

Choose the counting unit

Define what counts as a new opportunity for the clinic. Follow-up messages, administrative requests, and returning-patient visits should not automatically count as new acquisition opportunities.

Use consistent denominators

Booking rate = opportunities in the group that booked ÷ eligible opportunities in the group × 100. Attendance rate = completed appointments in the group ÷ eligible bookings in the same group × 100.

You can also track inquiry-to-appointment conversion by dividing opportunities that completed an appointment by the group's eligible total. Give these three measures distinct names.

Do not treat a simulation as a market benchmark

In the example below, the numbers were invented only to explain the calculation. An isolated rate does not indicate whether performance is good: that depends on definitions, audience, lead handling, and capacity.

Allow time for possible outcomes

Recent inquiries may still be in conversation, and future appointments cannot yet be classified as attended or missed. Separate ongoing opportunities and explain which events enter the calculation.

Review duplicates and rescheduling

Someone who rescheduled may appear twice in a booking report. To analyze acquisition, track the opportunity and its outcome. To analyze appointment-slot utilization, use a separate schedule review. These are different questions.

Use the rate to guide investigation

If booking rates changed, review who entered the group and what happened during lead handling. If attendance changed, review cancellations, rescheduling, and availability. A rate identifies a stage to investigate; it does not identify the cause on its own.
