I have create site at : http://examineonline.googlepages.com/index.htm Please help me about pointion of ads !
You might want to try to remove one ad placement (on the right or left) and place a nice block ad below your content in the middle.
Overall a good placement on both the sides. I would leave a ad above the fold too to get maximum CTR.
you placement looks cool but if you change the places of link unit and 336*280 ads unit. you can get better results
Definitly want to get your own domian. Also the add placement could use a bit of work. I like the overall layout though.
