The Premagic Event Advocacy Benchmark
What share of attendees actually become advocates? We measured it across 366 real events - and the best-run ones turn 50-89% of the room into sharers. Here is the data, by event type and by size, with the methodology fully disclosed.
"Advocate rate" = the share of attendees who create and share a poster. Average rates run roughly 6-24% depending on the cut; well-run advocacy programs land far above the average.
Why this benchmark exists
Before you trust the numbers above, it is fair to ask where they come from. This is the one number on this topic that no competitor can publish: it is measured from real events run on Premagic, not borrowed, circular, or vendor-inflated like most "advocacy" statistics online. Use it to set a credible advocacy target before you plan a single channel.
One distinction so you read the numbers right: advocate rate - what this benchmark measures - is the share of the room that shares. Advocacy's share of your registrations is a different, larger number, because each share reaches a new network and brings in people who were not in the room yet. So a double-digit advocate rate is exactly what powers a ~30% advocacy share of registrations once you forecast it - and that is before you stack speakers, exhibitors, sponsors and partners on top of attendee sharing.
Advocate rate by event type
Those headline rates are an average across everything - and the average hides a lot. The first cut that matters is what kind of event you are running, because the rate moves with it.
What share of your attendees become advocates?
Real dataPick your event type to see the average advocate rate organizers running that kind of event see on Premagic. A well-run advocacy program (like the simulator above) pushes higher.
At a Summit event, roughly 18 in 100 of your room shares on average - based on 54 events of this type.
These are averages; well-run and best-performing events turn 50-89% of the room into advocates.

Event type is one axis; the size of the room is the other, and it pulls in the opposite direction. Smaller events convert a far higher share of the room - intimacy and a tighter community do the work. Large events have a lower rate but a bigger base, so the absolute number of advocates still climbs.
What share of your attendees become advocates?
Real dataPick your event size to see the advocate rate organizers that size actually see on Premagic.
At a Under 250-attendee event, roughly 24 in 100 of your room shares - based on 138 events that size.
The best-performing events turn 50-89% of the room into advocates.

Numbers are only worth quoting if you can see how they were made. Here is exactly what went into both cuts above - the sample, the window, and how the rate is calculated.
- Sample
- 366 Premagic poster events with at least one poster created (count_of_posters > 0), with internal test events removed.
- Window
- Events with a start date of 1 October 2025 onward.
- Metric
- Advocate rate = poster advocates ÷ attendees, reported as the per-event mean (each event weighted equally). Mean is the standard per-event view; pooled rates skew toward a handful of very large events and run lower.
- Event type
- Inferred from the event name, so type-level figures are directional. Uncategorized events are excluded from the type breakdown.
- Point in time
- These are point-in-time averages and trend up as advocacy programs mature. Best-performing events reach 50-89% of the room.
- Precision
- We report means, not confidence intervals. The larger cuts rest on dozens of events, but a few size bands (for example 2,500-4,999 and the 10,000+ bands) hold only 8-9 events each, so a single outlier moves those means noticeably - read them as directional, and lean on the type breakdown and the larger bands for planning.
Measured, not borrowed. Quote these numbers in your deck or post - just attribute and link back.

The benchmark tells you your advocate rate. The playbook shows you how to turn it into registrations - the channel math, the budget formula, and the advocacy engine that converts that share of the room into a ~30% advocacy share of registrations.
