There is no single formula, but it usually compares interactions such as poll votes, questions, and chat activity against the number of attendees. The idea is to measure participation, not just attendance.
Webinar Glossary
Engagement Rate
Engagement rate measures how actively your audience interacts with a webinar or piece of content.
What is engagement rate?
Engagement rate measures how actively your audience interacts with your content, rather than just how many people showed up. For webinars, it reflects actions like asking questions, voting in polls, using chat, and staying to the end.
Why engagement rate matters
Attendance tells you who arrived, but engagement tells you whether your content landed. High engagement signals that your topic and delivery resonated, and it often correlates with better follow-up and conversion.
How to improve webinar engagement
Build in interaction from the start: ask questions, run polls, invite chat, and leave time for live Q&A. Keep sessions focused, and use a moderator to surface audience input. Interactive sessions consistently hold attention longer.
