I found that my most trafficked pages didn't pay very well as not many advertisers are paying for those pages keywords. Removing it from those busy pages means the data Google is getting about 'on load' is faster and the bounce rate is lower, it has a positive impact on the rest of the sites rankings. Enough of a positive impact to reward me more than an army of penny clicks would? I don't know yet.
