Making money on the internet is no easy business. It's a tough thing to get into. You might make a little money here and there, and maybe for a short period of time. But everyone looks for a long-term business which will bring them enough money on a regular basis. It takes time to build a business which will be good in the long run. It takes huge amounts of time and effort, and you have to give up some luxuries.
Advertising is probably the most easiest way to make money on the internet. Because the visitor of a site doesn't need to pay to look at the content, and the owner won't have much overheads. The hardest thing though is getting visitors to your site.
