Below adsense earning are from my golden time. At that time I was earning decent money by developing websites and also by blogging. Now for my profession I have to stop blogging as I have not spare time anymore. No spare time for blogging no spare time for family also :(
Earning $500-$800 in every month from adsense was common for me.
This is my highest adsense earning.
This may be my 3rd highest adsense earning (I have lost the copy of 2nd highest adsense earning)
