When you decide to promote, or point traffic to, eBay.com, you’ll use an affiliate link. An affiliate link includes a unique ID given to you by the merchant – at EPN, we call this a Campaign ID. Then, when someone clicks on your affiliate link, the affiliate ID gets stored on that person’s browser within a text file known as a cookie. The EPN cookie contains several pieces of information, called “parameters”, including Campaign ID, to help us track the eBay shopping activity of users after they click on your link to ensure you get paid a commission.affiliate-tracking
The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.
