Some websites allow you to engage in pay-per-click affiliate marketing without running your own website or blog. Direct links through outside merchant websites allow you to create and make money off of ads without having to post them to your own website. For instance, you might make an ad for a dating website and advertise on Facebook; when someone clicks on your ad, they go straight to the dating site, instead of a website or landing page you have created. Some affiliate networks that specialize in direct linking include Associate Programs, Affiliates Directory, E-commerce Guide, and Link Share.
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.
