Techopedia explains Affiliate Program
Affiliates decide within their affiliate programs which banners or ads they're going to place on their websites. This decision is based on their individual calculations of which company ads their website visitors are most likely to be interested in. They will also agree to affiliate programs based on which merchants have the best commission structure, although the structure is not usually considered very high-paying or profitable.
The most common forms of affiliate programs are pay-per-lead and pay-per sale. Affiliate programs are considered the least expensive online advertising tool for driving traffic to a website. Unlike pay-per-view or pay-per-click, affiliate programs pay based on performance.
