Privacy-Compliant Consent Management

A French professional training organization serving the healthcare sector implemented a consent management platform from Didomi in 2024 to address fragmented consent collection across multiple digital properties. Before the implementation, consent management lacked a centralized interface, limiting visibility into cookie and tracker impact. According to a 2025 Didomi case study, the organization increased its overall consent rate by 40% in less than a year by deploying customizable consent banners, restructuring web analytics with server-side tracking, and aligning with CNIL recommendations. The project also involved migrating from Universal Analytics to a compliant tracking foundation, demonstrating how consent optimization and analytics modernization can proceed in parallel.

A European vehicle rental company achieved up to 18% more consent and 12% more collected events after optimizing consent flows, according to Didomi case study data published in 2025. Separately, a European lingerie retailer gained 12% more traffic and reached a 68% consent rate through consent banner optimization. A major French telecommunications operator serving more than 25 million monthly users across web, mobile, and TV platforms implemented cross-device consent sharing, which increased consent rates by 10% by reducing banner display frequency for returning users who had already provided consent on another device. These examples illustrate that consent optimization yields compounding returns: each percentage point of additional consent translates directly into expanded data availability for analytics, attribution, and personalization across the marketing technology stack.
