I posted a thread about image vs text ads a while back, and the winner was obviously text ads. However, times have changed and I noticed that the description is no longer clickable on most Adsense text ads. So do image ads work better than text ads now or is it still general preference? Thanks.
They both pay out the same. http://adsense.blogspot.com/2006/03/cpm-ads-knowing-facts-can-pay-off.html
