You certainly already know what is fanpage is not it?
Yes, fanpage is a collection of thousands or possibly millions of people who love a page. A page could be a brand name of a product or artist's name or band name and so on. Do a simple research to determine which fanpage you will use later. After finding the fanpage, look at the interaction that occurs on the fanpage. Fanpage with a large number of fans like not necessarily good interaction. Once the conditions are met, the next step is to pay attention to who the FB account is doing the interaction. Do add friend only to fb account whose interaction shows interest if he seriously wants to buy something offered from the fanpage. And that needs to be considered in add friend is not to be too aggressive maximum every day add friend as much as 10-20 account just so as not blocked by facebook.
