I would not put the adsense code at the top of the document. Since bots will read it from the top down. And if you haven't been following this might have an effect on your rankings. Even though they say too much ads above the fold is bad, I also think too much ads at the top of your source code is bad.
I put my ads at the bottom and they seem relevant enough. All the way at the bottom. This also lets my website load before the ad code.
