CPA, or Cost-Per-Acquisition, is a digital advertising pricing model in which advertisers pay a fee for each specified action or conversion generated by their ad campaign. The acquisition can be any desired action, such as a sale, lead, sign-up, download, or other predefined goal.
Unlike traditional advertising models, where advertisers pay for impressions or clicks, CPA focuses on actual results and performance.
Advertisers set a maximum CPA they are willing to pay, and the advertising platform optimizes the campaign to achieve the lowest cost per acquisition possible while maximizing the number of conversions.
