The easiest thing to do is to sign up for an affiliate marketing network like Commission Junction. They provide a marketplace where your affiliate program will be advertised to other affiliate marketers. They also provide the tracking software for your affiliates so you don’t have to build your own tracking system. In some ways this is better because it takes care of the trust issues. Affiliates are always suspicious of whether or not they’re getting credited for the sales they generate. By having an intermediary take care of transaction tracking and payments, the fear of being cheated is alleviated. 
1. New vs. existing customers. New customers traditionally have higher lifetime value than existing ones. This is because every new customer grows your customer base. And once you own the customers, you pay less to convert them on future purchases. Customers who have purchased from you already know your product, value your service, and presumably trust you. It costs more to acquire a new customer because you have to build that credibility and trust.
(b) Obtaining Product Advertising Content. You may obtain Product Advertising Content by making calls to PA API. If we provide express prior written approval, you may also obtain Product Advertising Content through a data feed (“Data Feeds”) that we make available via file transfer protocol. To request our approval for access to Product Advertising Content through Data Feeds, contact us via this link. If you obtain Product Advertising Content through Data Feeds, your access to and use of Data Feeds is subject to this License. You acknowledge that we may change, deprecate, or republish PA API or Data Feeds, or any features of PA API or Data Feeds, at any time and from time to time, and you agree that it is your responsibility to ensure that your access to and use of PA API or Data Feeds is compatible with the then-current requirements (including this License and all Program Policies).

The Commissions Report table gives you information about your sales. You can see on what date they were created what type of plan was purchased, and the campaign from which the sale has originated. If you only refer clients with your affiliate link directly without using campaigns, you will see that in the column "default". The last 2 columns show what the status of a sale is and what commission you can expect for it.
In November 1994, CDNow launched its BuyWeb program. CDNow had the idea that music-oriented websites could review or list albums on their pages that their visitors might be interested in purchasing. These websites could also offer a link that would take visitors directly to CDNow to purchase the albums. The idea for remote purchasing originally arose from conversations with music label Geffen Records in the fall of 1994. The management at Geffen wanted to sell its artists' CD's directly from its website but did not want to implement this capability itself. Geffen asked CDNow if it could design a program where CDNow would handle the order fulfillment. Geffen realized that CDNow could link directly from the artist on its website to Geffen's website, bypassing the CDNow home page and going directly to an artist's music page.[14]
