I have been writing technical articles since 2004, but never really thought about monetizing my work until two years ago. I own more than a dozen websites, and it really becomes hard to maintain all of them. In the 4th Quarter of 2010, I started selling advertisements on Web Hosting Resources, and Geolocation websites and started generating passive income from them on a monthly basis. Due to the time it takes to find quality advertisers, and running and maintaining an Ad server is somewhat troublesome; I have decided to convert all of my Ads into Google Adsense. I have been running Google Adsense for nearly 8 months, and I am pretty happy with its results as compared to other advertisement networks I've tried including Adbrite and Chitika.
