In case you have been looking for a tip that I have tried and tested to increase your cpm. Please go to http://rudefox.com/increase-your-adsense-cpm/
Has anyone tested this to see if it really helps any? To me it doesn't sound much different than turning off Interest-based ads (which doesn't help either) in your account settings.
