Case Study: Semaine Health achieves 12.4% incremental lift and uncovers an 87% halo effect with WorkMagic

How Semaine Health Uncovered an 87% Halo Effect from Pinterest with A 3-Cell Lift Test

a major health brand, Semaine Health, was struggling to accurately measure the impact of its Pinterest advertising due to non-linear customer journeys across its DTC site and retail partners. Their click-based attribution was failing to show the true value of different ad types. To quantify the channel's incremental lift and halo effect without disrupting campaigns, they partnered with WorkMagic.

WorkMagic implemented its pause-to-measure, 3-cell incrementality lift test. This solution revealed Pinterest was driving a 12.4% incremental sales lift, with a massive 87% of those conversions occurring off-site on Amazon and Walmart. The test, run by WorkMagic, also showed that 50% of the incremental sales came from new customers, proving Pinterest's vital role in acquisition.
