Paid advertising — this method requires an effective combination of ad copy, graphics, and a highly-clickable link. Unlike more traditional affiliate marketing strategies, paid advertising (through pay-per-click ads) earn you money regardless of whether a reader buys the product or not. Services like Google's AdSense make this quick and easy for you, and can even supply you with an advertising code.
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.
