For each Affiliate that joins under your name, you get a second tier commission as a percentage of their earnings. As an example, if you promote the affiliate program by displaying the link below on your web site, potential affiliates may follow your link and joins the affiliate program. When these Tier 2 affiliates earn commissions, you will earn additional commission on top. For example, if the Tier 2 affiliates made $10,000 this month and your Tier 2 commission rate is 20% then you will earn an additional $2,000.
