Every event has a dynamic event page. It can be indexed on Google and search engines as well. When indexed by Google, it is listed in the special Google Events Search and brings new prospective members to the group.
In addition to the name of the group, event basics are displayed publicly such as the event name, date, time, photo, hosts, and location. Attendees are not displayed.
To index group events in Google search, set visibility in group admin settings to public.
Alternatively, if the event is Members Only, it is not shown on the group page, not indexed by Google or search engines, and remains private to all members in the group. No one can join the event without being explicitly invited or existing members of the group.
