With Facebook, the thing that I’ve found best is to make my own business page (see mine at https://www.facebook.com/TypewriteTranscription).  When I started out, I tried to be purely professional on there. Every single thing on there was business related. Slowly I began to realise that you actually have to let your personality shine through even on a business page on Facebook. This is because Facebook is a social platform and people like the interaction. So you can build a page, invite your friends and ask them to share. But the big thing is to be on there daily or as often as you can and write posts or content that is engaging. There was a time when I would have sworn to you that Facebook alone could be enough to market a business. Now I am not sure that you get your main business from Facebook purely. Facebook is part of a larger picture even in the online scenario. So it’s a good idea to have your own website, twitter, submit your link to business directories. And offline you can do things like print brochures, stick them in letter boxes, put them up in local post offices.
