What are your thoughts on suggestions from Google Adsense?

Anyone seen any suggestions from Google Adsense. It`s interesting that they`re pushing a non-standard IAB for me from 300x250 to 336x280.

Jim Munro: I do not know for sure, Kasey, I am not an expert, but I can say that we switched to these a while ago and, for us at least, they do earn more.
Kasey Moore: Thanks +Jim Munro, think I'll switch and see how it goes. It was just interesting that it's a depreciated standard from IAB. ;
Masatake Wasa: Unless you've opted out from similar-sized ads, 300x250 units also compete for the auction for a 336x280 unit, so theoretically you shouldn't be losing out: read http://adsense.blogspot.com/2013/06/getting-most-from-your-336x280-ad-unit.html
