Hi,
We all know that day to day earnings can fluctuate a great deal. I was thinking that a helpful thread could be a look back at the previous month and comment on changes that you have made.
For example my earnings September 2011 vs previous month (or September 2010) went up/down. During this time I changed the ad size or type.
There are many post in the "Month AdSense Earnings & Observations" regarding the daily earnings but few people mention if they changed anything.
This will (hopefully) provide all of us more data, confidence and ideas on what to change.

Last month I increased the number of leader board ads and changed all formats to image/text.
My over all earnings for September 2011 were up when compared to both previous month and September 2010
