Sup all. What do you think the best paying banner sizes are? I thought that the 336x280 were but after my new redesign of my site I went back to 300x250 and Ive been getting a very high CPM. All big company ads too, tylenol, nexium, sephora. Just curious how other people make out with the different size ads. Thanks
Definitely some large rectangle ads. Because, if you use 468x60, every other company has it, and there's a chance that you won't get some strong, well-paying companies.
In my opinion, I think that both the medium rectangle 300X250 and the large rectangle 336X280 have the same amount of eCPM.
