To give you a picture of how the back-end works for THCG:
InfusionSoft is the leading affiliate tracking software and powers our affiliate program. It uses combination of cookies and IP address to track referrals for the best possible reliability. When the visitor follows your affiliate link to our site, our affiliate system registers this referral and places a unique cookie on the visitor’s computer. When the visitor pays for their products, InfusionSoft affiliate system checks for your unique cookie (if not found, checks for your unique IP address of referral) and credits your account with commission. This process is absolutely automatic. All referrals are properly tracked but credits only the link that is clicked and a sale transpires. The unique link tracking software creates the ability for us to read the data needed to resolve questions such as the originating link ownership.
