Shatner, you're focusing too much on one factor. You can have 9 ads on a page, but does your content warrant 9 ads? Its the number of ads, combined with the placement combined with the non disclosure that can be causing them to be effected. It is extremely unlikely that any 1 given factor is causing this, google does not work that way, if they did they would be much easier to game.
