Webinar engagement starts slipping around 22 minutes in, only about 37% of viewers stay the full hour, and just over half of registrants ever show up. Those are the benchmarks worth planning around — but every figure here comes from vendor or aggregator datasets, not independent peer-reviewed research, so we label each as directional.
A note on rigor: there is no independent academic benchmark for webinar attention or attendance. So rather than dress vendor numbers up as definitive, we cite the source, the sample, and the caveat for each.
When attendees drop off (Contrast 2026)
The single most useful webinar stat is when you lose people — and the largest dataset puts it earlier than most presenters expect.
Contrast’s “Webinar Statistics 2026” report — built from platform data on over 1 million webinar registrants plus a survey of 524 B2B marketers — found, verbatim:
- “On average, webinar engagement begins to decline around the 22-minute mark.”
- “On average, 37% of viewers stay for the entire 60-minute webinar.”
This is vendor-sourced and directional, but it’s a large sample, and the implication is hard to ignore: if engagement starts eroding at minute 22 and nearly two-thirds of viewers are gone before the hour is up, the back half of a standard webinar is playing to a shrinking, drifting room. The fix isn’t a better slide at minute 40 — it’s giving the audience something to do well before minute 22, so they’re participants rather than passive viewers when the drop-off window opens. That’s the entire case for webinar engagement tools.
Registration-to-attendance (ON24 2025, Digital Applied 2026)
How many registrants actually show up is the other number every webinar planner needs — and the credible range is roughly 40–60%.
- ON24’s 2025 Webinar Benchmarks Report (drawn from millions of platform data points) put the average registration-to-attendee conversion at 57%. Of those attendees, 56% joined live, 45% on-demand, and 1% both. Vendor, large sample.
- A 2026 cross-platform analysis by Digital Applied — about 12,400 B2B webinars across ON24, GoTo, and BrightTALK (Q3 2025–Q1 2026) — found a median live attend rate of 41.6% (mean 46.2%; bottom-quartile cutoff 28.4%). Because it spans multiple platforms rather than one vendor’s book, it’s the most credible directional check on the “40–50% of registrants attend” rule of thumb.
Read together, these say: budget for roughly four to six of every ten registrants to attend live, and don’t be surprised if it lands closer to four. The lever that moves this number isn’t more reminder emails — it’s whether the live session is worth showing up for, which loops back to engagement.
Engagement and revenue impact (ON24 2025)
The reason any of this matters to a business: webinars are credited with pipeline — at least by the marketers running them.
ON24’s 2025 report found that 68% of marketers were able to attribute webinars to revenue, and 75% said webinars helped reduce cost-per-lead. These are self-reported vendor figures reflecting marketer perception and ON24’s customer base — not independent measurement — so weight them accordingly. Still, the signal is consistent: the webinars that earn that revenue attribution are the engaging ones, because an audience that drops off at minute 22 never reaches the call to action.
(One figure we deliberately leave out: the widely circulated BrightTALK “67% say live Q&A is their favorite engagement feature” claim could not be confirmed to a primary BrightTALK report, so we don’t cite it.)
The practical synthesis across all three sections: attendance is finite, attention erodes fast, and the revenue follows engagement. The highest-leverage move is turning the webinar from a broadcast into a conversation — live Q&A, anonymous questions, and instant answers — before the 22-minute cliff. A structured live Q&A layer is the most direct way to do that.

Beat the 22-minute cliff
The benchmarks all point the same way: your audience is shrinking and drifting earlier than you think, and the webinars that hold a room are the ones that make it interactive before attention starts to slide. Give people a reason to lean in — to ask, vote, and get answered — and the drop-off curve flattens.
PresEngage adds that interactive layer to any webinar: anonymous audience questions, upvoting, and an AI co-presenter that answers in real time and in 100+ languages, so the routine questions never stall you and quiet attendees finally speak up. It’s free for up to 25 audience members, then $29/month, with nothing to download.
