What is Cost per Action (CPA)?
Cost per action (CPA) marketing and advertising is a pricing model where the advertiser pays a fee only when a specific action is completed, such as a sale, sign-up, or lead. This model is often used as an alternative to traditional cost-per-impression (CPM) or cost-per-click (CPC) models, as it aligns the advertiser’s interests and focuses on a valuable action for the advertiser. You can calculate CPA as follows:
Advertising cost / number of actions = CPA
