Abstract: A lead acquisition, promotion and inventory management system and method are described that optimize the delivery and revenue of cost per acquisition (CPA) advertising programs, while implementing user targeting techniques to reach interested potential consumers. Clients, such as advertisers, can create a program to be implemented. Based on the program information, a number of leads is calculated that can be collected. The leads are generated by targeting and selecting qualified users from a user pool, and determining if they are compliant with the requirements of the program. Compliant leads are then allocated and delivered to the client.
