I know it's an anomoly.....but.... Taking into account the days I received normal traffic in the last 2 months there were 5 days I was away from my computer and thus never had a chance to check my adsense stats more than 2 or 3 times that day. Normally I check them 10+ times/day. On each of those 5 days my earnings were 50% higher than normal. Believe it or not!
I believe it. For two weeks in December I was nowhere near my computer, and December turned out to be my best adsense month to date. Strange.
