Hi I'm new here, I want to start a Facebook business, I already start building pages but I heard a lot of people talking about viral apps! I didn't understand anything at first, then I remembered some apps making auto posts in some people walls in facebook! so I think I know what's a viral app, but I still don't understand how to build them and use them in my business to make money or at least to grow my pages! So, if anyone has any idea about how build them and use them please share it with me! or at least if there are any educational sources or threads in BHW please put it here. I will appreciate that so much.
