Case Study: 3 Suisses achieves real-time sales attribution and automated deduplication to optimize marketing ROI with Eulerian Technologies

Attribution and deduplication of sales in real-time

3 Suisses, a leading French fashion & home e‑commerce group, faced increasingly complex customer journeys and high volumes of third‑party tags across affiliate and retargeting channels. To centralize tag management and accurately measure partner performance, 3 Suisses engaged Eulerian Technologies to deploy a centralized tag management solution with real‑time attribution and automated deduplication.

Eulerian Technologies implemented a universal tag, redirection‑based tracking and pre‑configured attribution rules (deployed in one month) so sales are deduplicated and attributed to the correct partner in real time. The result was elimination of double attribution, measurable time savings for marketing teams, reduced page‑loading times, more efficient traffic acquisition budgets and an increase in qualified traffic at equivalent spend, plus richer partner reporting and finer ROI control.
