Advice: Google Ad placement

Hi Guys

Want your advice on google ad placement on my site.

I have a side scrapper below my menu, and top banner next to my logo and for my 3rd ad block, i want to put in the page content, should i put al the top always? Or shall i put it lower?

Remove the top banner.

Put text links below your header but above your content. Put a block in the text below the fold, and a block or banner at the bottom of the page, in case people get that far.

Then test with a sidebar skyscraper.
