CPA stands for Cost Per Acquisition. In affiliate marketing, a CPA program allows affiliates to earn a commission whenever a referred client completes a specific action : such as signing up, making a deposit, or starting to trade.
Unlike ongoing revenue-sharing models, CPA usually provides a one-time reward for each qualified client. The exact commission amount and conditions depend on the program’s structure, but CPA models are popular because they can offer competitive payouts and clear qualification requirements.
