What does CPA stand for in CPA marketing?

In CPA marketing, CPA stands for "Cost Per Action" or "Cost Per Acquisition." It's a pricing model where advertisers pay a fee only when a specific action is completed by the user, such as making a purchase, filling out a form, signing up for a trial, or completing some other desired action. This model is attractive to advertisers because they only pay for actual results, rather than just for ad impressions or clicks.
