(Pro tip - if you ever want to show you appreciate those quiet folks, make a post thanking all those who do not use their voice. Say that you appreciate them and welcome them. They’ll like your post - and might even comment!).
(Pro tip - think about how you would try to find your group and call it that!)
(Pro tip - watchout for innocent looking profiles that want to point your members to their group. This is a poor practice and not recommended. Such people are permanently removed and blocked from my groups. And yes, Facebook sees that.)
(Pro tip - if you want to experiment with Facebook group tools, or learn them, without being public in your group, set up a new private group where you are the only member. Now you can do whatever you want with damaging anything or anyone!)
There are many more tools available and impossible to cover in detail here - get in touch if you'd like to chat about learning about all of them and when to use them.
And that should be your ultimate objective - somewhere people can talk to each other just as if they were down the pub - your pub ;)
I run OBVI-US, a creative facebook community and CRM management agency in Glasgow - do book a chat if I could help you develop or establish your Facebook group for your business and/or brand.
