One of their suggestions worked great for me. About two months ago got a message in my account; they suggested I replace the old 428 by 60 with the bigger 728 by 90 banner on my automotive site. Well, I have seen ecpm go up significantly on that site since. ECPM has gone up comparatively more than the increase in CTR. I guess you do get higher paying ads in the bigger blocks. And the drop in earnings in May has not really been on that site. In fact, this site has kept earnings reasonable or it would have looked really bad.
In hindsight, it may have been a no-brainer suggestion, but at the time I wasn't wise to it. So I am really thankful for the tip.
