Perhaps the content to ads ratio is all wrong and I need to thin out the ads a little.
I would look at this, and also at ad placement. If at first glance the ads stand out more than the content, that could be your problem.
Since you're seeing such a black and white difference between ads and no ads, then you can do some testing - try putting one ad below the fold, and see if that helps. Test your placements for number of ads and location to see if you can find a place both you and Google are comfortable with.
