CPA
CPA, or Cost Per Action, is a financial metric used in advertising to measure the cost associated with a specific user action, such as a purchase, sign-up, or download. Advertisers pay only when the desired action occurs, making it a performance-based model. This approach helps businesses directly connect their advertising spend to measurable results, ensuring they pay for outcomes rather than just ad impressions or clicks. CPA is useful for evaluating the efficiency of marketing campaigns and optimizing budget allocation to maximize return on investment.
