Cookie:
- Small file stored on a visitor’s computer that records information. For affiliate programs, cookies have two functions: to keep track of what a customer purchases and to track which affiliate was responsible for generating the sale and is owed a commission.
The vast majority of affiliate programs use cookies. When a visitor clicks on an ad, a cookie is placed on their computer that says where they came from. When they make a sale, the cookie fires off information to the merchant to tell them who the credit should go to. Cookies have a shelf life and often expire after 90 or 180 days. This allows the cookie to fire off information about the referring website for up to that amount of days if they come back and make their sale later. This also applies when generating leads.
