Cost Per Action (CPA) also known as pay per action (PPA) and cost per conversion is an addon for XYZ Admarket which allows your advertisers to pay for specific actions performed by a visitor on their websites such as contact request, newsletter sign up, registration, purchase etc. CPA is the best advertising strategy for an advertiser since it ensures that they are paying only for real and genuine actions.
As the number of conversions will be considerably less than than number of impressions and clicks, the minimum rate for CPA ads will be higher compared to PPC and CPM ads thereby ensuring that admin and publishers will not lose out on earnings.
