The adsense optimization issue: I have been testing google adsense on Explain Stuff site as I am doing some adsense optimization. And I come to this conclusion that more google adsense ads you put on the landing frame, <i>(My reference to frame here would be the visible portion of the screen the user sees when he/she lands on the page)</i>, the higher the bounce rate is. Why I think so? I used to have two big rectangles (336X268 ? )right below the post header, which is below the page header. So, it looked like this: Visit Adsense placements and why I think bounce rate also depends on Adsense and revenue also depends on the number of adsense items used.
