I know that there are many ways how to make money through twitter out there, but I ensure the one I am going to introduce you is the best. The website, banner of which you are going to find at the end of this post, offers a lot of sponsors that ask you to publish an ad at your twitter account, and you will get paid if any of your followers clicks on that ad (and trust me there a lot who do that). The price per click varies from country to country but it is not lower than 5cents. All you need is an account at Paypal, in order to make the transaction possible and another account at the website where the banner is going to redirect you.
