Repeat attendance rate

People vote on events with next year's diary. Marketing can inflate one edition's attendance, but nobody re-attends a show that wasted their time, which makes repeat attendance rate hard to fake and therefore worth watching. For organizers, the commercial logic is the same as any subscription business: returning attendees cost a fraction of newly acquired ones, they register earlier, and they're the population most likely to recommend the show to colleagues. A healthy rate also strengthens the exhibitor pitch — "our audience comes back" is evidence of a real community, not a rented crowd. In practice, measuring it needs person-level matching across editions, and the rate should be read alongside its mirror: new-attendee share. An event needs both returners and fresh faces; 80% repeat attendance can signal a beloved institution or an aging one that's stopped attracting anyone new. The common mistake is measuring repeat rate at company level and calling it loyalty — the company badge returning with three different junior employees each year is not the same signal as the same buyer returning. One honest nuance: the right rate depends on your market's rhythm. In industries with three-year purchase cycles, a modest annual repeat rate can be perfectly healthy; judge the number against how often your audience actually needs the show.
