The acquisition cost of a qualified prospect who left their contact details.
CPL divides ad spend by the number of leads generated: forms filled, demo requests, trial sign-ups. It's the central KPI for B2B businesses and long-sales-cycle services, where the purchase doesn't close online.
A CPL is only worth the quality of its leads: 50 leads at €30 that never sign cost more than 10 leads at €100 of which 3 become clients. Real management happens at cost per signed customer.
"We connect campaigns to the CRM to manage on qualified CPL (MQL/SQL) rather than raw leads, and feed quality signals back into the platforms' bidding algorithms."
