Cost per lead

Cost per lead, often abbreviated as CPL, is an online advertising pricing model, where the advertiser pays for an explicit sign-up from a consumer interested in the advertiser's offer. It is also commonly called online lead generation.

Contrary to cost per mille (CPM) and cost per click (CPC) pricing models, where advertisers are charged for impressions (a.k.a. "views") and clicks, respectively, in a CPL pricing model advertisers pay only for a qualified sign-up regardless of how many impressions or clicks their advertisement receives. CPL advertising enables advertisers to generate guaranteed returns on their online advertising money.
