In online earning, there are lots of method, some can help you earn a lot , some can help you loss a lot. I never invest online as I do not trust them. To earn by click banner is just mini money, the afford your put on it is not worth if you count on money you can earn per hour.
To earn more we can be a freelancer post our service in the internet. There are lots of ecommerce gratis, which is Marketplace platform for people to sell and buy services. For example, help to setup a blog with creative theme for 5 US. You may need to click lots of banner non-stop for a month to arrive 5 US. However, just a few click on the internet can setup a blog and with little time to design a theme. If you are a expert, it just a little afford. This way is the best method to earn from my view and it can help people at the same time. It is win-win marketplace.
