Write an e-book on a topic that is related to your affiliates. For example, if you team up with an affiliate that sells fitness equipment, you may want to write an e-book about different workout techniques that involve the fitness equipment. Embed affiliate links into sections of your e-book. For example, if your e-book is about fitness, you can write about the importance of wearing appropriate running shoes during your workout, then embed affiliate links for a specific brand of running shoes that you recommend to your readers.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
