The V7N Affiliate Program is one of the higher converting affiliate programs on the Internet.
Most webmasters have some degree of experience with affiliate programs. Most do not convert. This one does.
Why?
This is just a guess, but I'd say that the V7N Affiliate Program converts because it offers a valuable product at a bargain price. The V7N Web Directory is one of the highest trafficked web directories on the Internet, webmasters know it, and want to be included.
Payout is by PayPal.
