Just when I was about to lose my shirt about my LOW clicks and earnings this after noon, I gave google the benefit of the doubt and waited it off to see what the deal was and ... BANG.. my stats are back to normal and my earnings and clicks have been updated completely... swwweeeeeet! My point? Your stats/earnings may be in the process of updating as well. Ms. Pearl
On average web traffic in general is always down on weekends because people go out and do things on weekends and are not by there computer with no lives. It does catch up when google is down.
Geez people if you are really unsattisfied with Adsense then start selling banners and links directly to advertisers. Adsense is a nice program that allows you to check your stats in almost real-time unlike sites like kontera which usually waits for 1-2 days before they update your account. In addition to that, what difference does it make if they update it today or tomorrow? You are still getting paid the last week of September..
I also see the no of impressions in my adsense is down to almost half and also adsense was down for mantainence some time back.
