Cost Per Action or CPA (sometimes known as Pay Per Action or PPA) is an online advertising pricing model, where the advertiser pays for each specified action (a purchase, a form submission etc) linked to the advertisement. This model proved itself useful among thousands of publishers worldwide. MGID traffic which is being sold on a CPC basis, perfectly suits CPA-type promotions. Using our service, publishers have a marvelous opportunity for additional income.
