If you can't measure something it probably isn't a real or effective part of your business.
Click throughs. The software or program allows you to track and record the click throughs made by visitors to your site and others who have your referral link. In other words, you keep track of your marketing campaigns. Let's say you've got several links in several different types of ads in a campaign, such as Pay Per Click and email ads. You can give them a code which the tracker responds to when someone clicks the link. So you can gain figures on click rate and numbers for ads and the placing of those ads.
Details. By using a program like this you can get a lot of detailed information to help you make decisions about return on your ad investment in various ways. For example, you'll also know how many emails were opened, how many then clicked through to your site or the merchant's site, how many products were bought, which banner ads brought you the most leads and sales and so on through your various ad formats.
Decisions. Such data will help in deciding which affiliate programs are worth continuing with and which of your own products could benefit from different ads. It provides details for decisions about which marketing method fits which type of product and in which area. So, for instance, you might find an email campaign is better for sales of an affiliate product than using banners in particular places. Once you've tried various permutations you can decide which method is best for which product and whether to simply drop a product as not being worth trying to sell.
