I have one page on my site that brings in most of my AS revenue. I noticed via my AS tracking that the #1 clicked ad on that page is a MFA site. This ad is almost always showing in the #1 slot in the Google ad unit. People have mentioned blocking MFA sites as a way to increase revenue. But, isnt the fact that Google puts this in the #1 spot an indicator that it will bring me the highest price per click? Or is that wrong? If I block it, and Google shows the #2 ad, will that pay less?
