Okay. I was really pumped. I had my campaign all set. I had my affiliate links ready to go. I started putting promos out left and right; Facebook, PPC on Bing Ads and Adwords, Twitter, Google+, etc. Then, after a while, I got a sale! Then lo and behold, I got another. I need to do this again, I thought. I’ll put the ads out again where I got the sales from. Just one thing. I didn’t know where my sales came from. Instead, now I had to put ads out to all of them again, not knowing which ones were worth the effort. That’s when I realized the importance of link tracking.
