Many people believe that in order to make money online, you have to have a website. This is far from the truth. In fact, you can start making money online without a website and without any sort of investment.
One of the sites that I use to make a full time income online is Hubpages.com. There are several ways you can use this site to make money and the built in community is always fun.
This article, How To Make Money On Hubpages, gives the lowdown on how you can use the site to your advantage.
Being an affiliate marketer is by far the best income source when using Hubpages so you'll still need to learn a little about that if you want to make substantial amounts of money with Hubpages. Otherwise, learning affiliate marketing is optional.
