What are they for:
When your Social App is submitted, all its social features get revealed, including the Interest Tags. Appropriate application of this feature encourages networking on your event and helps to break the ice between the attendees.
How it works:
Tags that you add to the builder are available to the attendees in their profile settings. They can add one or more tags to their profile, so other attendees with the same tags can find them by using the in-app attendee filter.
You can add any tags that would best fit your event, starting from hobbies (Sports, Photography, Cycling) and ending with the attendee’s role at the event (Planner, Speaker, Investor, Sponsor). Just use your imagination!
To add interest tags, go to the Social Settings section of the Settings pane and scroll to the bottom:
Later attendees are able to select relevant tags in profile details to let other participants know their interests:
