No problem at all. At least you understand that you will need some unique content. My suggestion to you and others is to not concentrate on the "ads" them self but on something you have a passion about. After you have a nice following of readers it will just grow form there and the revenue will grow as well. You can sell Ad's on your site for a set amount etc.. Work on your site then worry about the ads. Don't put the buggy before the horse cause if you do you wont go any where Get a nice plan together then duplicate it. Best of luck
