Case Study: PromoFarma.com achieves 300% traffic growth and unified TV-to-sales attribution with Eulerian Technologies

Measure the impact of TV campaigns on an e-commerce website sales

Promofarma.com, a leading Spanish online parapharmacy marketplace, needed to measure and incorporate the impact of newly launched TV campaigns into its digital strategy and centralize all online and offline acquisition data. To achieve unified, deduplicated attribution and real-time reporting across channels, Promofarma.com partnered with Eulerian Technologies and deployed the Eulerian Data Decision Platform, using its analytics and attribution modules to track investments, sales, CPA and full user marketing histories.

Eulerian Technologies implemented a TV-specific measurement approach—logging broadcast times, calculating baseline visit rates, attributing excess visits within client-defined time windows, and deduplicating sales to integrate offline and online metrics in one platform. In less than a year Promofarma.com recorded a 300% increase in marketplace visits, a sixfold rise in referral visits, improved campaign ROI visibility (e.g., identifying more effective days and slots for TV), greater marketing autonomy, and optimized customer acquisition spend.
