Understand the basics of how affiliate marketing works. Many online retailers who sell products or services offer affiliate programs. If you decide to sign up for a company’s affiliate program, you get a tracking link to put on your blog. When visitors click on that link, the link stores a cookie in their browser that remains for a set period of time, such as 60 days. If the visitor purchases a product from that merchant site within the time period, you earn a sales commission.
Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives a commission. The advertiser must convert that visitor first. It is in the best interest of the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss are shared between the affiliate and the advertiser.
