I just found out something very interesting and useful about AdSense, might not be totally legal though.Plase give your comments.
This trick allows you to increase your eCPM. As you all know, there is a "publisher id" that Google AdSense provides you. As some of you might have experienced before, once you delete the publisher id, the ads will keep being shown on the site, but you will be publishing them for no cost by Google's side. So you will be publishing freely. I will tell you something that won't bother you to leave your AdSense code without a publisher id for 4-5 days.
