My programmer generates customized links for our affiliates who drive traffic to our site....
They can track impressions and clicks with this, which I understand and already bought program to recreate these links
We have a contact request form that visitors fill out and thus become a lead
Affiliates can track this too with the same original link
So there must be some sort of pixel tracker when they hit submit that integrates with affiliate tracking url
Need explanation of this, how I can reproduce it myself to work with my new software, and person to do it
