Memories
Back in they heyday of affiliate marketing, you could make thousands of dollars per month just by using Google Adwords. Now that they have changed the program, it is a lot more difficult. It is better to focus on building your own content to sell affiliate products.
Sites That Allow Affiliate Links

There are two basic types of communities to join when it comes to affiliate marketing, electronic and physical products. Commission Junction focuses on selling physical products. This can be anything from flowers to web hosting to video games. Anything you can think of is probably available to sell on Commission Junction.
Signing up for Commission Junction is a relatively easy process. You just give them your information (name and email address, and they will allow you to join) You will have to supply them with tax information before you can get paid though. This is a small nuisance to make money online.
