Two-tier programs exist in the minority of affiliate programs; most are simply one-tier. Referral programs beyond two-tier resemble multi-level marketing (MLM) or network marketing but are different: Multi-level marketing (MLM) or network marketing associations tend to have more complex commission requirements/qualifications than standard affiliate programs.
StudioPress is a WordPress hosting service and framework that is designed to make setting up and running a WordPress site much simpler and easier. StudioPress comes with its own unique themes and SEO tools, collectively known as the “Genesis framework.”. Their affiliate program is solely for referrals to pay for a StudioPress framework account or buying a StudioPress theme. Previously, the affiliate program also included web hosting, but this is now managed separately by StudioPress’s owner, WPEngine.
