Facebook group is a wonderful feature on Facebook to create a community. By building a Facebook Group, you will be able to build a community where meaningful discussions can happen or where you can market and promote your products. If you want to create a group on Facebook, you should first define your community's purpose and values. You need to set clear goals like whether it would be open or closed, whether you will manually approve posts or they appear automatically. Your community is not just a bunch of people hanging out, it should be providing resources or assistance in your chosen niche.
