CPL, which stands for Cost per Lead, is a measurement used in digital marketing to determine the cost of acquiring a potential customer. It represents the expenses incurred by advertisers or marketers for generating leads or interested individuals. In simple terms, it quantifies how much it costs to capture the contact information of a potential customer. Advertisers pay for each lead they obtain through their marketing efforts, and the cost per lead is calculated by dividing the total advertising expenses by the number of generated leads. The goal for advertisers is to optimize their CPL by improving targeting strategies, refining messaging, and enhancing the conversion process to ensure maximum return on their marketing investment.
