Cost per lead is one of the most important metrics in lead-generation advertising. It tells you what each inquiry costs, which lets you connect ad spend to pipeline and, ultimately, revenue.
CPL is only half the story, though — a low CPL full of unqualified leads is worse than a higher CPL of sales-ready prospects. The goal is a low cost per *qualified* lead, which depends on targeting, tracking, and conversion quality, not just bidding.
Example
If you spend $3,000 in a month and generate 60 leads, your CPL is $50 ($3,000 ÷ 60).
How Sloss Digital uses it
We optimize campaigns toward cost per qualified lead, feeding lead-quality data back into the platforms so they find more of the leads that actually convert.
