- Event attendance figures alone cannot measure experiential marketing success or prove ROI.
- An Outcomes Rocket survey found 68.9% of marketing and sales professionals lacked confidence in the event ROI figures they presented to leadership.
- Audience participation, including product trials, meeting bookings, questions and post-event conversations, provides stronger engagement indicators.
- Brands should define commercial objectives and measurable audience actions before an event begins.
- Linking attendee engagement to leads, sales pipeline activity and conversions helps demonstrate experiential marketing ROI. *
Brands are putting more money into live experiences. In the UK, the IPA Bellwether report just showed the strongest upward revisions to event marketing budgets in nine quarters.
What comes back after the event usually looks the same as it did ten years ago: a headcount, a photo of the queue, maybe a reel with good numbers. None of that says whether anyone cared.
Nunify, an event management platform, puts it bluntly in its guide to event marketing plans: “track engagement” isn’t a KPI, and the numbers that matter have to be named before the event starts, not after.
Nobody trusts the number
Marketers are mostly honest about this when asked. A survey of 87 senior marketers in Australia and New Zealand found just 2% are very confident measuring return on below-the-line spend, and almost a third said experiential was their primary measurement challenge.
One respondent said counting the basics was easy. Their problem was proving the person at the January event was the person who bought in March.
B2B teams aren’t doing much better. In Outcomes Rocket’s September 2026 survey of 841 marketing and sales professionals, 68.9% had given leadership an event ROI figure they weren’t confident in.
That’s seven in 10 people presenting a number they privately doubt. It works until a CFO asks a second question.
Attendance measures the wrong thing
Headcount gets reported because it’s easy to pull. But it mostly reflects your invite list, the venue and whether it rained.
It doesn’t even guarantee memory. ZEAL Group and Censuswide surveyed 2 000 UK adults and found only 26% recall seeing or taking part in a live brand experience in the past year. Age made a big difference: 48% of Gen Z remembered one, compared with 9% of baby boomers.
A footfall figure can’t tell a room that was paying attention from a room that walked past on the way to the coffee.
What counts as participation
Participation is something a person chose to do when they didn’t have to. Booking a meeting counts. So does asking a question in a session, trying the product, scanning a code to hear from you again, or mentioning the event to a colleague the next day.
The last of those gets missed most. ZEAL found that 96% of people who remembered an experience took some action afterwards, and the most common one was simply talking about it in person or on the phone. Their argument is that brands measuring only public posts and clicks are missing part of the response. The research is self-reported, and ZEAL says plainly it can’t prove the experience caused the action. It still shows where to look.
In India, EY-Parthenon and BookMyShow made a similar case in their report on experiential marketing, with EY-Parthenon’s Raghav Anand calling audience participation “the new currency of relevance”.
Measuring it in practice
Start with the brief. Before anyone designs anything, write down the one commercial result the activation is for, whether that’s pipeline, trials or sign-ups. Then list the two or three things attendees would do if it were working. If the team can’t agree on those actions before the event, there’s nothing to measure after it.
Plan who you want to talk to. Outcomes Rocket found 74.2% of booth conversations at respondents’ last major event were unplanned, and only 32% of teams set meeting goals beforehand. A conversation nobody planned rarely gets logged, so it never shows up in the ROI.
Attach actions to names. Only 39.2% of teams in the same survey tag every conference lead to the event it came from, and 28.9% said nobody clearly owns the event pipeline. Engagement you can’t tie to a person won’t survive a pipeline review.
Capture it on the phone. That’s the one device everyone at the event is holding. Salesforce does this at Dreamforce: attendees use the event app to see their agenda, bookmark sessions and book meetings, and Salesforce can now connect what people did there to what happened in the sales pipeline afterward.
Then ask about the parts no tool records. A one-question follow-up survey (“Did you tell anyone about this?”) picks up the conversations ZEAL says most brands miss.
What to report next time
Keep the headcount. It’s the denominator. Add how many of those people did something, what they did, and what happened afterwards.”2 000 people came” invites a shrug. Telling leadership how many booked a meeting or tried the product, and how many of those are now in pipeline, gets you next year’s budget.
