Business Hangouts offers comprehensive reporting on all of your events. Reporting includes attendee contact lists, absent attendees, and pre event registrations. You will know when your attendees entered the event and when they exited the event. From this, you can calculate how long each person attended, the average watch time and many other statistics.
We even give you stats on your whole organization when you have multiple accounts with us.
All registration and reporting information can be exported in spreadsheet format.
