Yes, affiliate marketing works. Many people earn a good living from it. I personally bring in a decent percentage of income from doing this.

It is hard work, especially at first, and you have to know what you are doing. I have two suggestions. First, join the Warrior Forum (free). This is a forum where Internet marketers hang out and exchange information. It is excellent you need to be there because the members have much to teach you. It is all free.
