A Tracking ID is an alphanumeric string of up to 100 characters, including numbers, lowercase letters, and underscores, that you can add to the end of a HopLink. Your Tracking IDs are visible only to you as the affiliate.
When a customer follows a HopLink with a Tracking ID, and when they purchase a product, the Tracking ID is linked with those events. You can use tracking IDs to differentiate between different sources of traffic and compare your promotional methods.
For example, let's say you're promoting the same product on a blog, in a forum post, and on Twitter. You could use three different Tracking IDs with the same Clickbank account and this would help you track each medium.
