Cost per acquisition where the acquisition is a lead: a form fill, a phone call, a lead-form submission inside a social platform. CPL is the standard unit for B2B, services, and any business with a sales cycle that runs after the click. A cheap CPL with poor lead quality is more expensive than an apparently high one, so CPL is best reported alongside a qualified-lead rate.
