To boost the penetration of its peanut butter range, Menguy’s relied on a highly targeted media strategy, orchestrated by M6 Unlimited and Unlimitail. The objective: to generate an immediate impact on in-store sales.
Running from January 16 to February 9, 2025, the campaign combined the reach of M6+ with the precision of Carrefour’s transactional data. The results: 1.2 million impressions delivered to strategic audience segments.
The targeting strategy was built on two complementary levers: family-oriented contextual targeting on M6+ and Carrefour shopper data focused on audiences relevant to the supported products.
Results that speak for themselves:
- +11% sales uplift on peanut butter products
- +5.5% sales uplift across the entire Menguy’s brand
- +3.8% increase in average basket value
- 55% new brand buyers among those exposed
This activation demonstrates M6 Unlimited’s ability to design bespoke campaigns that combine media reach, targeting precision, and business efficiency, all driving brand performance.
It also highlights the value of Carrefour’s transactional data operated by Unlimitail, which transforms media exposure into tangible business outcomes, including on channels such as CTV.
