Product Content That Sells:
DERTOUR'S Winning Strategies for the Digital Shelf
MasterClass | 24.06.2025 | 16:15–16:45
DERTOUR – a real-world success story: mastering complexity in tourism retail.
How does an international tourism group create, manage, and distribute product and campaign content efficiently—and, most importantly, profitably?
In this Masterclass, CELUM together with Burcu Özduran, Project Manager Special Websites/Online Projects at DERTOUR Germany, offers exciting practical insights: from the challenges of handling content that must convey emotion and ensure a consistent experience across all booking touchpoints, through the requirements for a scalable solution, to measurable successes.
The core question: how can brands structure their product content to make an impact on the digital shelf? The key lies in consistency, brand alignment, instant availability, and seamless distribution across all channels.
CELUM Founder & CEO Michael Kräftner shares his perspective on the future of digital commerce. What challenges lie ahead for retailers and e-commerce businesses — and how can a strong content supply chain help them stay ahead of the curve?
