It is important to note, however, that StudioPress is now a subsidiary of WPEngine which is the company that actually does the web hosting on which StudioPress’s Genesis framework runs. The affiliate program only works with choosing the StudioPress framework and themes, not the actual hosting on WPEngine. WPEngine has a separate affiliate program for its hosting services, which yes, is a bit confusing.
JVZoo was founded in 2011 and has since rocketed to near the top as one of the most popular affiliate programs out there. JVZoo is unusual in that there are no upfront costs for either publishers or merchants (advertisers). JVZoo’s income is exclusively from charging fees (to both the merchant and the affiliate) after a sale has been made. It is also unusual in that it pays commissions “instantly” via PayPal rather than once a week/fortnight/month like other affiliate programs.
