Personal data is crucial for brands.
How can its collection be optimized in a context of increasing legal constraints and growing user suspicion?
By Gimii

Since the implementation of the GDPR in 2018, regulations about user consent for the use of personal data for advertising purposes have become more stringent for websites. On average, across all sites, 41% of users do not accept cookies. When consent is not given, page revenue is nearly 2.5 times lower for ad-supported sites. And for advertisers, in a no-consent context, ad campaigns generate around 5.5 times fewer conversions. These figures show just how vital consent is to monetizing advertising campaigns. However, obtaining consent is becoming increasingly difficult, due to rising user awareness and tighter legal constraints.

Indeed, the CNIL (France’s data protection authority) is continuously evolving its guidelines around privacy. One controversial case is the paywalls (i.e., “accept cookies or pay for access”): the CNIL attempted to ban them, but the French Council of State overturned the decision. In addition to these legal uncertainties, internet users are increasingly reluctant to allow their personal data to be processed. Privacy scandals—especially involving tech giants—have further eroded trust, making users less willing to give consent.
Moreover, CSR (Corporate Social Responsibility) goals—such as the need to reduce carbon emissions from advertising campaigns by limiting data processing—must also be considered in this complex equation.

Brands today face numerous and often conflicting challenges: complying with tightly enforced regulations, regaining user trust while handling personal data, persuading without pressuring, guiding without manipulating, targeting better without excessive tracking, growing revenue while reducing emissions…

Hybrid and innovative solutions like Gimii’s can help meet these challenges.
Gimii aims to work within the new legal landscape while offering a fair alternative—combining responsible advertising with privacy protection—to create a meaningful compromise that benefits both brands and users.
