How to earn money on web?

This is a question I always ask with myself. I spend a lot of time to get answer to this question. I never got satisfacton getting answer to my question. The best option to earn money could be Adsense owned by Google. Other options could be by posting youtube videos, Adbrite etc.

I am trying to get more sources to get revenue of your own effort. I will make these public once I get to it.

Thank you all people.
