Affiliate marketing owes its birth and first developments to CDNow.com and Amazon.com. Back in November, 1994 CDNow started its Buyweb Program — the first online marketing program of its kind at that time. Amazon continued this pattern in July 1996 with its Associates Program. Amazon claims that currently the number of their affiliates worldwide exceeds 1 million associates. (A Practical Guide to Affiliate Marketing, p. 11)
I’m not sure of the exact reasons why I started to rank, but I have a few theories. It was a very long, honest, and informative post on the subject. I believe this made it stand out from all the other reviews in which the author just wrote up a basic summary of what it’s about. It also is one of the latest reviews on the book, so perhaps google freshness has something to do with it. I haven’t done any linkbuilding on this page and it currently sits at #2.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
