If an affiliate changes the terms of its program, your revenues could be directly affected. Choosing the wrong affiliates can also be problematic if your blog or website audience doesn't feel compelled to buy their products or services. With the affiliate-marketing industry experiencing a boom, you’ll also have to contend with competition from other marketers shilling the same affiliate products.
The last thing I would say to new affiliate marketers is that self awareness is SO important. It’s easy to get caught in the routine of doing what you think is working, when it’s actually not working. Always be looking at what others are doing in your niche; always be re-evaluating your game plan; and always be thinking about new ways to hit your audience.
The concept of affiliate marketing on the Internet was conceived of, put into practice and patented by William J. Tobin, the founder of PC Flowers & Gifts. Launched on the Prodigy Network in 1989, PC Flowers & Gifts remained on the service until 1996. By 1993, PC Flowers & Gifts generated sales in excess of $6 million per year on the Prodigy service. In 1998, PC Flowers and Gifts developed the business model of paying a commission on sales to the Prodigy Network.
