Case Study: CPEx improves cross-domain consent management with Didomi

How does CPEx collect user consent across 300 websites

CPEx, short for Czech Publisher Exchange, is the biggest association of Czech online media operators, managing a network of 300 websites across 15 publishers. As GDPR requirements grew more complex, CPEx needed a flexible Consent Management Platform to handle diverse publisher needs, improve reporting, and support customization across many domains. They turned to Didomi for a third-party CMP solution after finding their in-house and previous provider options too difficult to maintain and adapt.

With Didomi’s Consent Management Platform, CPEx gained cross-domain consent sharing, detailed analytics and reporting, and extensive banner customization options, including custom CSS, layouts, colors, logos, and A/B testing. Didomi helped CPEx stabilize consent rates despite an industry-wide decline, improve understanding of user behavior, and deliver a better privacy user experience. The result was a more flexible, stable, and scalable consent setup across all 300 domains, supported by responsive Didomi technical support.
