Customer story : Galeries Lafayette & PlatformX

Overhaul of data collection : the winning strategy of Galeries Lafayette to boost consent rate

A renowned fashion leader with 130 years of history, Galeries Lafayette is a cornerstone of the retail industry, offering both French and international customers a curated selection of brands spanning accessible, premium, and luxury segments. With 19 company-owned stores and 38 franchises, the brand has a strong presence across France. It is also accelerating its international expansion, particularly in the Middle East and Asia, with 12 stores open or in development.

FEATURES USED

Galeries Lafayette rely on the following features of PlatformX

• Enterprise Tag Manager with CAPIs / Server-Side destinations
• Consent Management Platform (CMP)

CHALLENGE & GOALS

Like many in the industry, Galeries Lafayette has seen a gradual decline in both the volume and accuracy of data collected on its e-commerce platform. Two primary factors are driving this trend: the phasing out of third-party cookies, increasingly blocked by major web browsers, and the rising adoption of ad blockers, which prevent some tracking methods and limit data collection.

SOLUTION

The decline in consent rates appears to stem from user fatigue with standardized banner formats, leading to reduced engagement and attention. To counteract this trend, the team leveraged PlatformX’s CMP A/B testing feature to experiment with banner variations.

RESULTS

The impact was immediate. The consent rate grew to 85%, not only surpassing previous levels but also exceeding the market average, as reported by the Commanders Act barometer. This 10-point increase has re-established a solid foundation for analysis and optimization.
