Adsense rocks but your blog stinks...move over to self-hosted and optimize for Search Engine traffic. Also your adsense placement really really is horrible!
Yes, you'll struggle with that layout. You have to scroll right to the bottom of the page to see you (tiny) adsense advertisment. It is best to have atleast one ad towards the top of the page. So, if you happen to have a high bounce rate, atleast there is the slim possibility that the way out will be through one of your adverts. And with your search facility down the bottom, why not use search from adsense?
Try to run your own study of your ads earnings. Track your earnings where this come from and try to use other ads type and placement.
Oh your blog is about "helping others make money online", so i'm guessing your "tips" don't work at all then since you are needing the "help"
