Stands for Pay per sale. In the PPS program, affiliates get paid only when the visitor completes sales at the advertisers website. The publisher will get a commission for every sale made through his affiliate link. The commissions vary from 10% to 50% depending on the product offered by the merchants. Getting a website visitor to purchase a product requires a lot of work and merchants understand that the compensation must be worthwhile. While signing up for PPS programs, affiliates usually receive a marketing package with various marketing tools that they can use to drive visitors to purchase the product. Affiliates can taste success with PPS programs only when they have a niche website with a dedicated audience.
