Two-Tier Affiliate Programs are a type of affiliate marketing program where the affiliate not only earns a commission on the sales they generate, but they can also earn a commission on sales generated by other affiliates they refer. This type of program allows an affiliate to benefit from the traffic of other affiliates they refer, as well as their own.In a two-tier affiliate program, an affiliate is rewarded two levels deep. This means that if an affiliate refers another affiliate, they will earn a commission on any sales the referred affiliate generates. This is beneficial for two reasons. First, it allows an affiliate to benefit from the success of other affiliates they refer. Second, it encourages affiliates to refer more affiliates, thereby increasing the size of the program.For example, let’s say that John is an affiliate for a company that offers a two-tier affiliate program. He refers Jane to the program. Jane then starts promoting the program and generates several sales. John then earns a commission on each of Jane’s sales. In this scenario, John benefits from the sales generated by Jane, as well as his own.
