How are anonymous participants counted in the attendee report?

[scj13]

When we host a webinar, we look at the attendee report to see how many people joined. I noticed, though, that this report only includes people by name and email. We do allow people to join without signing in, and one participant during the webinar was listed only as "anonymous". Does anyone know if these anonymous attendees still counted in the report? Mostly curious if the attendee report is a true count of all the people who attended.

The attendee report would not include emails for anonymous attendees as well as double counting attendees who drop and rejoin and does not reflect total time in session. You could use APIs to aggregate total time in session per attendee to get a more accurate webinar attendance report. If you are not a developer there is a marketplace app, Salepager, that can do this for you.
