@thegeekguy What you're asking is about to open up a whole new world that exists right in front of you but you never knew it. The knowledge will blow your mind out. I suggest that you start a new thread and ask your question "What Ad companies do you recommend ?" or reword something along those lines. Post it in the correct thread for maximum responses.
@evil People still make money from adsense but the problem has always been your lack of control in displaying highly targeted ads to your visitors. General ads from adsense CAN work but targeted ads from other companies are much more LIKELY to work. Adsense is very much luck of the draw and google rules can be infuriatingly anal in what they do an do not allow. I'm a newbie in most things related to domains but ads I can help you with from first hand experience although I'm not claiming to be some sort of guru. There are probably hundreds of Namepros lurking in the shadows with an obscene amount of knowledge about monetising domain names with ads.
@evil You don't need to work for years but often you find the biggest success in your second or third year because you have seen the full cycle of visitors and you have statistics to understand the trends at different times of the year. Try oribi, adobe, statcounter or google analytics. Some people still use the default statistics offered by your hosting provider C.M.S. control panel software.
