This is probably one web-based business that presents a low entry barrier, which also explains partly the huge popularity associated with affiliate marketing.
With affiliate marketing, you are not involved in the creative part of the work, like conceiving products or services.
As an affiliate, your main responsibility is to move products made by others in order to earn a commission.
Some of these digital products include e-books and short reports.
If you have trouble sourcing products for sales, then you might want to check out websites such as ClickBank and PayDotCom, which represent two of the biggest affiliate networks out there.
