The graphics I showed are not to scale. The column that the 336 adblock is in is only 500 wide, not really room for text to flow around it and still look good (IMHO). I do have an image next to it on some of the pages though.
i removed my 728x90 ad, and just left a small links unit on the left side of my page. many ppl think it's content from my site
Yea i signed up for it recently, like today, and have 0 . lol. is it worth it to do the ad share on this site?
"Flow" means nothing when it comes to making money. The first requirement for making money with Adsense is to let go of any preconceived design ideas you might have.
I strictly follow the Google Visual Heat map and it is working well for my website. Also, I have documented whatever Adsense optimization tricks I learned over the time here: http://labnol.blogspot.com/2005/09/z-adsense-tips-for-increasing-revenue.html
