But that doesn't make any sense. Surely it is impossible for this to be a stat or other technical problem?

If you earn $100 a day from traffic for 6 weeks, then suddenly earn $1 a day for 2 weeks (despite no change to traffic source or volume) then there is some fraudulent behaviour going on with Google?

My PPC ads across several industries have not suddenly dropped in price. Is it really true that Google just stops tracking clicks for Adsense publishers sometimes? Is there a quarterly investors report coming up soon that they need better figures for? There must be an answer.
