Cofidis is a leading European financial services company specializing in consumer credit and personal loans, primarily delivered through digital and remote channels. Headquartered in France, its portfolio includes personal loans, revolving credit, auto financing, debt consolidation, home equipment loans, insurance products, and payment solutions - all delivered with a commitment to responsible and accessible lending.
In 2025, Cofidis set out to strengthen consideration for its diverse credit services by reaching highly specific audience segments without relying on third-party cookies, thanks to innovative programmatic targeting strategies.
The need for Cofidis to identify, reach, and engage the right audience at the right time meant addressing multiple personas, each with specific needs and interests. For this reason, six distinct personas were identified for this campaign, each requiring tailored creatives to enhance relevance and engagement.
The challenge had two dimensions:
This required a targeting approach capable of combining scale and granularity, without compromising performance.
In close collaboration with Dentsu and Cofidis, Adlook deployed a multi-phase, privacy-first digital strategy designed to test and refine several ID-less targeting solutions:
In Q1 2025, we tested Adlook’s full set of identity-agnostic capabilities in order to compare the contribution of each method in reaching different personas and driving qualified traffic across Display and Native formats. This multi-tactic approach enabled benchmarking of Adlook’s cookieless strategies, and revealed Prime Audiences as the most effective solution for engaging Cofidis’ high-value niche personas - demonstrating that precision and scale can be reconciled without relying on third-party cookies.
Building on these insights, we focused the Q2 2025 plan on the most effective targeting tactics to maximize efficiency. Prime Audiences was deployed into five parallel behavioral pools, moving from broad targeting to greater granularity. This enabled both broad reach and hyper-specific targeting, perfectly aligned with Cofidis’ different customer profiles.Finally, an additional intelligence layer was integrated through attention measurement with Adelaide and carbon footprint tracking with Scope3, thereby adding quality and sustainability to every delivered impression.
“This campaign has shown us that it is possible to reach the right audiences with precision, performance, and respect for privacy. The Adlook DSP solution not only exceeded our expectations in terms of engagement but also delivered measurable sustainability gains — proof that performance and responsibility can go hand in hand.”

Digital Lead, Cofidis
The partnership delivered remarkable gains in efficiency and engagement across all key KPIs:
In addition, our measurement partners observed a +25% increase in attention scores and a -67% reduction in CO₂ emissions compared to benchmarks.
These results validated Adlook cookieless solutions as truly effective, proving that ID-less targeting can match (and exceed!) the performance of cookie-based tactics while delivering measurable sustainability benefits.
“The partnership with Adlook allowed us to confidently navigate the cookieless landscape for Cofidis. By testing multiple targeting strategies, we identified effective and scalable tactics, perfectly aligned with our client’s objectives and with the industry’s shift toward privacy-first marketing.”

Client Director, iProspect, Dentsu
The insights from H1 2025 have laid the foundation for an innovation roadmap of the Cofidis-Dentsu-Adlook partnership in H2. With Adlook established as a top-performing solution, the next phase will focus on unlocking even greater efficiency through pre-bid attention optimization and deeper audience personalisation. By building on proven tactics and integrating advanced media quality signals, Cofidis is well positioned to continue driving high-value engagement while setting a benchmark for sustainable, programmatic excellence on the Open Web.
“The Open Web has long faced inefficiencies, fragmented supply chains, and a reliance on outdated targeting methods. With Cofidis, we wanted to demonstrate that it is possible to overcome these three obstacles — by using high-tech targeting solutions to reach precise, cookieless audiences at scale. These campaigns show that with the right programmatic strategy and tailored innovations, brands can achieve exceptional performance, full compliance with privacy standards, as well as measurable gains in media quality and sustainability.”
