Case Study: Clarins achieves 20% more deduplicated conversions with Commanders Act (OneTag + Facebook CAPI)

Clarins has 20% additional deduplicated conversions thanks to Server-Side with Facebook CAPI

Clarins, a leading European prestige skincare brand present in 150 countries across 30+ e‑commerce sites, needed more accurate conversion tracking to boost acquisition, loyalty and optimise marketing spend while ensuring consent compliance and real‑time data quality across its global sites.

Commanders Act implemented server‑side tracking with OneTag and Facebook Conversion API (CAPI) across Clarins’ World, Asia and America sites, enabling reliable, privacy‑safe event routing and real‑time monitoring. The rollout delivered about 20% more deduplicated conversions via CAPI versus the Pixel and increased first‑party data onboarding by ~40% on page views, giving Clarins finer audience segmentation and improved campaign attribution.
