I'm familiar with Twitter and Instagram but I've recently become interested in growing my Facebook page. Currently I have 750 likes which I am very pleased with seeing as I have rarely advertised that page and post maybe 1-2 times a month. I want to focus more on the Facebook page and try to get UK/US people following it. How do I advertise and grow this page (without spending a single penny)? I tried posting a link to my page on popular groups but I get banned from the group. If I add lots of strangers then my account gets disabled. What do I do?
