Unless you are selling advertisement I would recommending using one of these companies and you become a publisher. You are paid base off CPM every 1000 views not click you earn money. They will rotate advertisment through your site where ever you place their code. You can select from many different banner sizes. Remember, you would want to sign up as a publisher, and if you would like to advertise you can sign up as an advertiser.
