Tracking Links

Yea so, forgive the retarded question but I am a total noob at this and am just learning. I'm working on my first campaign and want to promote using Clickbank hoplinks for a product that I think could do well. How can I track the link to make sure if a customer buys the product I earn the commission. Thanks in advance for any help out.

Click bank has an interface for that, its under reporting, if your advertising on a site you own, use any analytics software out there. Google analytics is free.
