Measure
Cost Per Lead (CPL, CPC, CPM)
What one enquiry costs you — and the three abbreviations every advertising platform reports it in.
In the platform package
What it is
A lead is somebody who has raised a hand: an enquiry, a form, a call, a booking request. Cost per lead is spend divided by leads. The related abbreviations are CPC — cost per click, what you pay for one visit to your site — and CPM — cost per mille, what you pay for a thousand people to see the ad. CPL is the one that matters commercially, because clicks and impressions do not book appointments.
Why it matters to your bottom line
- The cost of online advertising rises every year and will keep rising. Every practice competing for the same patients pushes the price up, and no clever setting reverses that.
- Because that cost is largely outside your control, the winnable game is what happens after the lead arrives — how fast you respond, how many times you follow up, and what the patient is worth over time.
- A practice that can afford a higher cost per lead than its competitors can simply buy the market. That capacity comes from the back end, never from the ad account.
How it works here
Separate the three
CPM is what you pay for attention, CPC for a visit, CPL for a hand raised. A cheap CPC with an expensive CPL means the traffic is arriving and leaving — that is a site problem, not an ad problem.
Track the lead, not the click
Enquiries land in one place with their source attached, so you can see which channel produces people who actually book rather than people who merely arrive.
Judge it against lead value
A R300 lead is expensive or cheap only relative to what an average lead earns you. That comparison is the whole decision.
Questions owners ask
- My cost per lead went up. Should I turn the ads off?
- Not on that fact alone. If lead value went up more, the rising cost is affordable. Turning off a channel because its cost rose, without checking what it returns, is how practices shrink their way to a problem.
- Why do platforms report so many different numbers?
- Because most of them describe activity rather than outcome. Impressions, reach and engagement are inputs. Leads, bookings and revenue are outcomes. Only the outcomes belong in a business decision.
