Key Takeaways
- ON24 reports 60% registration-to-attendee conversion when live and on-demand attendance are combined.
- Livestorm reports a 47.7% live show-up rate across 33,786 qualifying webinar sessions held in 2025.
- Nearly half of Livestorm registrations occurred in the final seven days, including 15.3% on the event day.
- Attendance, no-show, and replay rates need separate denominators so one person is not counted twice.
- Post-event work includes identity cleanup, replay delivery, question routing, consent handling, and CRM reconciliation.
Webinar registration and attendance statistics need a denominator beside every percentage. A live show-up rate answers a different question from total audience conversion after a recording becomes available. Treating those measures as interchangeable can make a routine change in viewing behavior look like a campaign gain or loss.
Two current platform datasets illustrate the difference. ON24's 2026 benchmark reports 60% registration-to-attendee conversion across live and on-demand viewing. Livestorm's 2026 benchmark, based on events held in 2025, reports a 47.7% live show-up rate. These figures are useful together because they describe different stages of the same funnel. They should not be averaged.
For teams managing registration records, reminders, and follow-up, the gap between registration and attendance is also a workload forecast. Every registrant must receive the correct confirmation and event access. Afterward, attendance status determines whether the next message should contain a replay, an answer to a question, or a sales handoff.

What counts as registration-to-attendance conversion?
Use unique, valid people in both parts of the calculation:
unique attendees / unique valid registrants x 100
That formula still needs a viewing window. For live conversion, count people who joined while the webinar was running. For total conversion, define how many days of on-demand viewing count after the live session. A seven-day and a 30-day conversion rate can both be correct, but they cannot be compared without the window.
Remove test users, staff, obvious bots, and duplicate registrations before calculating the denominator. Decide whether a person who joins from two devices is one attendee. Platform reports may count sessions while the CRM counts contacts, so the two systems can disagree even when both work as designed.
ON24 reports a 60% total conversion rate and says 52% of attendees watched on demand. Livestorm reports 175 average registrants and 83 average live attendees, which aligns with its stated 47.7% live show-up rate after rounding. The lower Livestorm figure does not establish weaker performance. It excludes later viewing and comes from a different platform population.
What is a useful webinar attendance benchmark for 2026?
A practical starting range is about 48% for live attendance and 60% for total attendance when on-demand viewers are included. Those are reference points from current vendor datasets, not universal targets.
Livestorm analyzed 33,786 sessions from 3,199 organizations between January 1 and December 31, 2025. It excluded test and internal events, sessions with fewer than 10 registrants, and sessions shorter than 15 minutes. That filtering makes the benchmark more interpretable, but it also means a private customer workshop or small executive briefing may not belong in the comparison.
ON24 describes its figures as global 2025 data from thousands of digital experiences. Its customer benchmark feature uses more than 23,000 customer webcasts over a rolling 12-month period and lets users compare by sector, industry, and event purpose. The more specific comparison is usually the better one. A product demonstration, professional training session, and broad thought-leadership event attract different audiences.
Track the same event type over time before treating a platform benchmark as a performance verdict. List size, traffic source, topic urgency, time zone, and whether attendance is required can shift the result.
Registration timing makes reminders operationally important
Livestorm found that 49.6% of registrations occurred in the final seven days. The breakdown included 26.2% registering two to six days before the event, 8.2% one day before, and 15.3% on the event day. Only 16.4% registered at least three weeks early.
This timing creates two different reminder needs. Early registrants need help retaining the date. Same-day registrants need immediate confirmation, a working join link, the correct time zone, and a fast route for access problems. A fixed reminder sequence can mishandle both groups if it sends messages based only on the event date rather than the person's registration time.
Livestorm says teams with show-up rates above 60% use personalized reminders at three days, one day, and the event day, among other practices. That observation is descriptive, not a randomized test of reminder frequency. It identifies a pattern among higher-performing teams but does not isolate reminders from audience quality, topic, or promotion channel.
No-shows are a reporting group, not a dead list
The basic live no-show rate is:
valid registrants with no live attendance / unique valid registrants x 100
Livestorm's 47.7% live show-up rate implies a 52.3% live no-show rate under the same eligibility rules. Its published averages make the volume tangible: 175 registrants, 83 live attendees, and 92 live no-shows per webinar.
Do not label all 92 people as lost. Some may watch the recording, and ON24's benchmark shows how important that behavior has become. Fifty-two percent of ON24 attendees watched on demand. Because a person can attend live and return to the recording, teams should document whether live and on-demand audience counts are mutually exclusive before adding them.
A clean report uses separate fields for registered, attended live, watched on demand, and did neither within the measurement window. It can then show a live no-show rate, replay conversion among live no-shows, and total audience conversion without double counting.
Post-event administration is part of webinar performance
The platform ending the broadcast does not finish the event. Someone still has to reconcile registration and attendance records, suppress test accounts, check consent, send the recording, answer questions that the speakers missed, and route requested follow-ups.
Zoom's webinar reporting documentation separates registration, attendee, performance, Q&A, poll, and survey reports. That structure explains why one export rarely contains everything needed for a complete campaign record. The attendee file may show presence while the Q&A report holds the question that determines the follow-up owner.
Post-event administration should record at least:
| Field | Why it matters |
|---|---|
| Unique contact ID | Prevents duplicate people and devices from inflating totals |
| Registration timestamp | Shows which confirmation and reminders the person could receive |
| Live attendance | Supports the live show-up and no-show calculations |
| On-demand attendance and date | Measures replay conversion within the declared window |
| Question or CTA | Routes a concrete request rather than a generic attendee list |
| Consent and suppression status | Prevents an event registration from overriding communication preferences |
| Follow-up owner and completion | Makes handoff work visible and auditable |
Teams that run frequent events can assign this work to a documented operating queue. Our guides to funnel building for webinars and virtual assistant services cover the campaign and staffing context.
A measurement plan that survives comparison
Publish the live show-up rate first, then total conversion after a fixed replay window. Keep the event purpose and audience source beside both figures. If the platform and CRM differ, reconcile identities before presenting a percentage rather than choosing the more favorable total.
For each event, retain the raw registration export, attendance export, calculation date, exclusion rules, and final counts. Track delivery failures for confirmations and reminders. A no-show caused by an invalid email or failed calendar invitation is a different operational problem from a registrant who chose not to attend.
The 2026 benchmarks provide a sensible frame: about half of valid registrants attend live, while on-demand viewing can raise total conversion materially. The strongest report keeps those behaviors separate and turns each status into a clear next action.
