The question seems to be, how do you make money on the internet?
It's actually quite simple:
1. Know what people are looking for. People are always looking to make their lives better, so weight-loss, personal improvement, how to quit a habit, and how to become wealthy are always common things people in general are interested in.
2. Have what the people are looking for. You can design your own product, or you can find one that is already in place that you can get money by selling or directing people to.
3. Market the product. Many people think this is the hard step, but it is actually the easiest. The internet is full of places to advertise. Some free ways are blogs and craigslist. Other times you have to pay, like google adwords or if you buy leads.
The internet is exploding so it is a great place to make money. Some ways make a decent amount of money, other ways are profoundly lucrative. Check out what I mean:
