I have started writing for one of them and have been paid. I am going to start a new blog discussing my online writing endeavors and more about these websites.
Freelance writing of articles. They have thousands of topics to choose from and you get paid $15 for most articles 400-500 words and $7.50 for fact sheet articles, 150-200 words. You can also suggest article topics and get $5 each for them.
You write the article, it goes to a copy editor, who either approves it or sends it back to be rewritten. Then you can either rewrite or just abandon it. You get to write 10 articles at a time. All of the articles need a reference and you may need to research some titles a little longer. I have found google books to be a great way to research and have a credible citation.
You alsoget paid twice a week, which is awesome. They pay via paypal, which you can then transfer to your bank account.
A site composed of about 32 different blogs. You sign up and can write posts for any blogs. The only requirement is 200 words and the pay is pretty low, $0.50 a post but can add up if you write a lot of posts. You can pretty much write whatever you want. You get paid through paypal once a month if your account balance reached $25 the previous month.
They pay you $10 to write articles in categories that you choose. However, it can be hard to get into more mainstream categories.
They pay $2 for everything you review and you can review absolutely anything.
