Considering this, who can see what you post in a public group on Facebook?
The content shared in Public groups is visible to anyone on and off Facebook, and the member list is visible to anyone on Facebook. With these changes, it is more likely that more people will see, and may interact with, the content posted to Public Groups. This includes people who may not be members of the group.
Also Know, can everyone see posts in a public group? Public groups are just what they sound like: public. Anyone can see the group's name, location, member list, and posts, and the group can show up in anyone's searches or News Feed.
Keeping this in consideration, can you post in a Facebook group without friends seeing?
Unfortunately there is no way to choose to hide it from certain friends. If you post in a Private group, then only the other members of the group will be able to see your posts. For Public groups, everything you post inside the group will be visible to all your Facebook friends.
Can my friends see my comments in a public group on Facebook?
They will be able to see your comments in public groups but not private groups of which they aren't members. Public groups are public so they can scroll through the page, but if they're not a member, that group's posts won't show up on their feed.
