Hello, How are your adsense earnings improving? Here is my adsense earning curve since I started using adsense in october 2006... (modified for better reading) Create yours at http://www.digitalpoint.com/tools/adsense-charts/ and tell us what you did to earn more revenue from adsense.
Adsense is great and it improves gradually. It makes the bulk of my income. You just have to push a lot of traffic to your sites and this means knowing how to get them to the top of the serps or close to. My adsense income is much higher than my affiliate income.
