I hear people say that it is possible to earn some money when people click on adverts that Facebook places on the right hand side of one's facebook page. (It cannot work with a Facebook profile or group, it must be a Facebook Page they say). Does anybody know where I can get clear info about how this can be done, please? How to enrol, do you have to have a PayPal account or a bank account associated with the pay-per-click procedure? etc.
