It's not just selling, clicking on ads and doing old school things. There are actually many more websites that can help you make money doing a lot of creative things.
Of all the services that exist, I'm writing here the most popular ones so you can get the most out of the information I'm giving.
Squidoo
Did you know that you could make money just by writing about things you like? At Squidoo you can create hundreds of pages which would bring you money every single month. The amount of money you get depends of several factors, of course, but you'll learn them easily in day or two if you actually start writing and participating in the community.
PayPerPost
Blogging can make you serious money too at PayPerPost. If you have a popular blog, you can go and write reviews or do sponsored offers on it. In return, you'll get 50$ to 1000$ for every written review. This is very good if you have a popular blog and a loyal audience.
Thirty Day Challenge
I've noticed in recent months that many “complete suite” websites appeared which told you they are going to teach you for free to start making money online. Well, Thirty Day Challenge is the most popular one. To make things interesting, they made a free challenge to make your first $10 online. I like the concept.
Tutor
Tutor has a very original idea. You get paid to tutor people. You basically share knowledge and get paid. If you're skilled into something, you can help children to better “get” their school material. Perfect if you're a school kid and even more perfect if you're a schoolteacher.
MetaCafe
Did you know that you could actually make money producing videos online at MetaCafe? If that's your hobby, why not make some buck out of it. MetaCafe has one of best services out there to help you achieve this goal.
