How Smart On-Site Triggers Drove Engagement at the 2026 Men’s Water Polo Championship in Belgrade
Live sports events generate emotion, atmosphere, and unforgettable moments but converting that excitement into measurable digital engagement is where real value is created for clubs, leagues, and sponsors.
Seyu’s data-driven fan engagement activation showed how well-designed in-venue touchpoints can connect with fans at exactly the right moment, when they are most open to engaging and considering merchandise. These positive shared experiences, created by the event’s fan engagement service, helped turn excitement into action.
The standout takeaway was an exceptionally high 38% Pop-Up Click-Through Rate (CTR), a figure that represents best-in-class performance for live sports environments.



From Atmosphere to Action: What Happened in Belgrade?
Over the course of the event, Seyu-powered fan selfie activations captured:
24% of attendees interacted with Seyu’s fan photo channel and enjoyed the activation, which once again proved to be a socially inclusive tool, with an average of 2.46 fans featured in each image.
These figures already signal strong participation. But the real business impact became visible in what fans did after engaging with the activation.

Why the 38% Pop-Up CTR Matters
One of the central mechanics of the activation was a digital pop-up banner displayed to fans after their selfie experience. This pop-up invited them to take the next step and engage further with content, offers, or digital assets.
To put this in context:
- Typical event-based digital pop-ups often sit between 5–15% CTR.
- Anything above 20% is generally considered very strong.
- 38% signals that the creative, timing, and relevance of the message were exceptionally well aligned with fan behavior and emotions in the arena and beyond.
This suggests three key success factors:
- Perfect moment of relevance: Fans were already excited, engaged, and visible on screens.
- Clear value proposition: The pop-up wasn’t just advertising; it offered something fans actually wanted.
- Seamless user journey: One tap, no friction, immediate payoff.

Wallet Pass Adoption: A Second Major Win
Beyond clicks, the campaign delivered another impressive outcome. 63% of the fans who showed interest in merchandise saved a long-term digital discount card for year-round use, enabled by Seyu’s wallet card solution powered by passes saved directly to fans’ phones.
This means hundreds of spectators chose to:
- Add a branded digital pass to their phone
- Stay connected beyond the event
- Create a direct, owned communication channel for future matches or activations
High wallet pass adoption is particularly valuable because it transforms a one-time attendee into a digitally reachable fan—opening doors for:
- Increased sales
- Personalized messaging
- Loyalty programs
- Sponsor integrations
- Retargeting and engagement campaigns
In other words, the event did not just capture attention. It built a sustainable digital fan base.
Marketing Opt-In: Trust + Interest Combined
Another critical metric was the 87.66% marketing opt-in rate.
This means nearly 9 out of 10 engaged fans were willing to receive future communications, an outstanding level of trust and interest for a sports activation.
For rights holders and organizers, this transforms a single championship into a long-term engagement opportunity rather than a one-off event moment.
Key takeaways
The 2026 Men’s Water Polo Championship in Belgrade demonstrated how a well-designed, data-driven fan activation can turn excitement into measurable engagement.
With a standout 38% pop-up click-through rate, strong wallet pass adoption, and an 87.66% marketing opt-in rate, the campaign showed that real-time digital touchpoints do more than entertain fans. They create lasting relationships between fans, teams, and organizers.
Most importantly, the case shows that when technology meets emotion at the right moment, live sport becomes not just a spectacle, but a powerful engagement engine.
