What Gets Indexed In Buddypress

By default every page those are visible for the logged out users will be indexed including member’s profile. You can use BuddyPress Lock plugin to make your website private and as per choice hide some or all BuddyPress pages for logged out users for more features you can also check the paid plugin BuddyPress Private Community Pro that will limit your BuddyPress community features for logged out users and in this way stop them from indexing on google.
