Comparing August 2012 with 2003?
Page Views [minus] 70.04%
Clicks [minus] 91.63%
CTR [minus] 71.85%
EPC [minus] 40.70%
RPM [minus] 83.50%
Earnings [minus] 95.05%
Page views largely reflect the Google Zoo. The clicks and CTR would reflect tightening the click area etc which we all know. EPC I can't fully explain but the rising $A would account for most of it.
RPM and Earnings reflect all of the above.
