what is s4s and how we can do s4s on Facebook
Shout out for shout out. You tell people to follow a person, then they will do the same. If its a popular page it's a scam to get more followers so only do it with friends
On Facebook, S4S means Share for Share. It is used by administrators on various pages, where they post your name on their page and you post theirs. The method has proven to be effective in getting more "likes".
