CPA

Cost Per Action, also known as Pay-For-Performance or Cost Per Acquisition. This is a large part of the mainstream affiliate marketing industry. In a CPA program, affiliates are paid based on the action of a user. In a pay per action program, once a customer that has been referred to the merchant completes a predetermined transaction, the affiliate is paid. For instance, in eBook affiliate marketing, an affiliate might be paid $10 for each referred customer that purchases a new book.
