Madame Coco, Turkey’s leading home textiles and décor brand, operates across 3 countries, attracting 100M annual visitors and 7.5M social followers. Despite this scale, they lacked accurate conversion data, limiting campaign optimization, budget allocation, and audience building.

The Challenge

Within our traditional pixel-based processes, we needed improvements driven by the reasons below in order to simplify ROAS tracking optimization and better understand campaign performance.

Key Problems:

  • Safari ITP & iOS privacy updates blocking cookies
  • Ad blockers reducing data accuracy
  • Cross-device behavior complicating attribution

The Solution

Partnering with OneIngage, Madame Coco implemented Hardal’s server-side tracking via Meta’s Conversions API:

  • 99% event coverage bypassing browser restrictions
  • Real-time, privacy-compliant data from e-commerce backend
  • Advanced customer matching enriching 40% of purchase events
  • Event quality score: 8.7/10, far above industry average

Impact and Results

  • 110% increase in tracked purchases vs. pixel-only
  • Improved attribution accuracy across all markets
  • Better ROAS through Meta’s enhanced optimization
  • Larger, high-quality audiences for remarketing
  • Data-driven decisions for international growth
