Get paid by showing ads on your website

Sign up for Google's Adsense program.
A good company that converts traffic into revenue. A classy company with a successful program. A plus is that it fits in nicely to any website without making it look trashy. People don't like to be bombarded with ads, so text is a good idea for your own website. That's why I use it. I'm just like you, it's nothing personal, I just don't see that there's anything to lose from gaining a little bit of money no matter what the site is about.
Some sites are following-:
1-: https://www.google.com/adsense/login/en_US/
2-: www.adbrite.com
3-: www.claxon.com
