3. Attrition Rate
The Attrition Rate represents the average fraction of your event registrants who didn’t attend the event after registering. The formula for calculating attrition is: (number of absentees / total registrants) x 100.
You can assess the attrition rate for both virtual and in-person audiences separately to know which event strategy proved less effective. There can be many reasons for registrants to miss your event. You can send out emails to your event registrants asking the reason for missing the event. This will help you in planning your future marketing strategies to overcome those issues.
4. Email Open and Click Through Rate (CTR)
Sending customized email with compelling CTAs is one of the best strategies for event broadcasting, content sharing, sending invitations, and gaining ROI. To know if your email marketing strategy is working or not, consider the click-through rate (CTR) of every email you broadcast. CTR tracks the total number of participants who clicked on the link in your mail out of all the participants in your mailing list. Though the average event CTR is a little less than 5% today, you can improvise on the specific content strategies that get better CTR and potentially increase the number of participants in your virtual and physical venues.
5. Attendee Satisfaction Rate
Response rates for live polls and surveys are also another valuable metric for measuring attendee engagement at your hybrid event. When your attendees are interested in your event they get actively involved in surveys, live polls or Q&A sessions held during the event. With the right event app or virtual event platform, you can have attendees vote in live polls or ask questions during an event session. This response rate will indicate the audience engagement levels and help event organizers understand which sessions were most successful.
