Placing Google Adsense Ads Below Post Title in Blogger? http://blogknowhow.blogspot.com/2009/05/place-adsense-below-post-title-blogger_04.html
nice hack. it probably will get your account banned. the ads will appear to all post in a page and that your ads will be more than 3 once you displayed 7 entries in the home. and that's alarming.
Man how many ad units are you putting on your single page remove that make it only 2 or 3 then only your click rates will be high ...
Why will it get banned, if he is using 2 adsense blocks, one after the post title and one after the end of post text. I think its absolutely fine. And about using more than 3 ad blocks? then forget it cause even if you use more than 3 ad blocks, they simply won't appear at all.
Usually anything you have to ask "Will this get my Adsense account banned" is not worth the risk. I think you have to have some content after title then the ad.
