First, users entered their email addresses on a splash page. This first step was essential since we wanted to capture emails both for our list and so that we could use it as an identifier for tracking referrals.
the second page was where the referral mechanisms lived. It contained a shareable link to the splash page coded specifically to the user. Below the page were buttons to share the link through email, Facebook and Twitter with the click of a mouse. By sharing the link with friends, users had the opportunity to earn free product. The more friends who signed up using your unique referral, the bigger the prize you earned.
