If you are building You Inc business, you should know your target market. How to know more people in your target market? The fastest way is through Facebook group. Join Facebook groups that are relevant to your target market. You can add them to become your friends. BUT, if they don’t know you, they may not approve it although they know that you are from the same group. When you have many pending requests for friends, you will get a warning from Facebook. One thing that you should not do on Facebook group is to promote your business directly unless the Facebook group is for the purpose for business promotion. You will be expelled from the group; people dislike you and you are building a bad reputation instead of good reputation.
