Using 234x60 ad like the one at the top of this forum will generate more for you than using a 336x300 ad. Take my example : I had 3 X 336x300 ads on my webpage and only get average $0.07 per click. I had 3 x 234x60 and got roughly $0.30 per click. Summary: 3 X 234x60 gives you better earnings
I'm not arguing or denying your results, but there are more factors than that, a lot of it has to do with specific site layout as well
Yes, it depends on a number of factors... Many people have different results depending on site layout, blending of ads, etc... A lot of people have been known to say the Skyscrapers, 160x600 are terrible, however, this is my most top clicked ad on one of my sites...
Well, Get one and only one 125x125 ad (not CPM/Image Ads) run in your site and you would generate double of what you are earning per clicks Try it if you want to..! More no. of ads displayed, that less will be the click, and the top most ad will pay the most..! so try one and get awsome result Tried and verified already
