How to track advertising campaign with 2.2.x?


I recently just started testing a few ads on a forum website. The graphic banners when clicked on will just take the user directly to the product page. Is there some simple way in CS-Cart 2.2.x that can track each click and overall see if they make a purchase?

Such as in the referring URL like but then add a tracking code to that like

Then just in CS-Cart I can see if that click lead to a purchase.

I do use other things like Google Analytics and AddThis … but not sure how to set them up (if even possible) to track those specific ad banner clicks to see if they lead to a purchase. On the website itself where I placed two ads, they have stats which will show clicks and impressions but that is it.

Thanks for any suggestions!
