Ok so I just realized that when you put a link in your twitter biography that the link is clickable as long as you have the http on the front. Now what I have done is used my biography to advertise my affiliate program..put a brief description with my affiliate link. Then just follow people and for every person you follow and who also follow you back your affiliate link will be visible on their followers page. If you follow 200 people then boom your affiliate link is under all 200 followers pages. Now the only thing is I have seen very little traffic from using this method. So my question is do people actually read others biography before following them? What can I do to get people to notice my biographies? If done right this could mean serious traffic!
