Case Study: FNAC achieves full cross-platform attribution and improved acquisition ROI with Adjust

How FNAC made the move

Fnac, one of France’s largest retailers, built a mobile app to respond to rapid mobile growth but faced a major attribution challenge: purchases occurred in an in‑app webview, breaking the normal tracking flow. Their previous attribution provider couldn’t reliably stitch together the app-to-web customer journey, so Fnac needed an advanced cross‑platform solution that could migrate historical data without skewing install metrics.

Fnac selected Adjust for its webview capabilities and dedicated, hands‑on support. Adjust’s integration (including tailored workshops and on‑site help) restored historical data and enabled tracking of installs, custom member IDs and purchase events, while consolidating partner integrations. As a result Fnac gained clearer user‑journey insights, improved acquisition optimization, and the ability to run customized retargeting and re‑engagement campaigns.
