I read a great article the other day by Melissa Culbertson from BlogClarity.com.
It was called “How to Easily Shorten and Track Affiliate Links.” For a lot of people that are first getting into affiliate marketing, this is something they overlook. I promise you however, that you most definitely want to be tracking your affiliate links. The fact of the matter is, you only have so much energy. You need to know what you are doing that is effective and what you are doing that is not effective. Knowing where your traffic and sales are coming from are a big part of that.
I created this simple summary infographic based on the original work of Melissa. Hope it helps! -Kam
