Though we have to make money from our content, but i think less is more when it comes to online publication. Even on TV , Have you ever watched a TV station when shows you adverts in the middle of an interesting program. OMG that can put me off. I have tested some thing on one of my sides, i removed ads from my content and kept only two ads one on the side and a small one at the top. Page views increased to and CTR also increased. Meaning readers will reward you if you don’t interrupt them with ads. Look at a site like businessinsider , you will read with no interruption all their ads are outside the content.
