I'm not a huge Adsense earner, but I've been aggressively pushing on increasing my earnings this month. I think many DP members are pretty clued up on improving Adsense revenues, but I thought I may as well post my story anyway: http://www.ibrian.co.uk/15-02-2007/how-ive-increased-adsense-earnings-by-40/ The bottom line, as has already been said at DP, is to experiment - and also focus on what you find works in terms if income generation with the higher paying keywords. Still pushing.
