Meta on Monday announced an update to Facebook Groups that enables admins to switch their private groups to public while keeping existing members’ privacy intact. Past content will remain confidential after the change, and member lists will stay protected.Many admins start groups privately, expecting them to stay small, but later realize they can reach a wider audience if the groups are more discoverable. This update allows groups to expand without creating a new public group or exposing prior posts.To change a group’s privacy setting, admins can use the Facebook settings page. When switching a private group to public, all other admins are notified and have three days to review and revoke the change if they disagree.All past group content after the update, including posts, comments, and reactions, will only be visible to members who were in the group before the conversion, as well as to admins and moderators. The Group members’ list is well protected and is only visible to the admin team.Group members will also get a notification about the change and will be reminded again when they post or comment for the first time in the newly public group.Once public, all new posts, comments, and reactions will be visible to everyone, including non-Facebook users, just like any other public group. This change may also improve Facebook content’s visibility in search engine results, such as Google, by allowing these groups to be more easily indexed for relevant queries.The update also allows admins to decide that being a public group isn’t the right call; they can convert the group to private again.
