Cost per acquisition

Definition

Cost per acquisition (CPA) is a marketing metric that measures the total cost incurred to acquire a new customer, including all associated marketing expenses. This metric is crucial for evaluating the effectiveness of advertising campaigns, particularly in social media, as it helps businesses understand how much they are spending to convert potential customers into actual buyers. A lower CPA indicates a more efficient advertising strategy, which is vital for maximizing return on investment.
