Case Study: OLLY uncovers cross-retailer Amazon ad impact with Stackline

OLLY uncovers 48% off-Amazon attributed sales with Stackline

Olly, a vitamins and supplements brand, faced a challenge in quantifying how their Amazon advertising campaigns were influencing sales at other major retailers like Walmart and Target. Their traditional tools could not provide a complete picture of this cross-retailer impact. To bridge this measurement gap, they partnered with vendor Stackline to implement its Multi-Retailer Attribution platform.

Stackline implemented its solution, which used verified transaction data to deterministically match Amazon ad views to purchases across other retailers within a 14-day window. This revealed that 48% of the total sales attributed to Amazon Ads actually occurred off Amazon, nearly doubling their ROAS. The insights from Stackline empowered Olly to shift from an Amazon-first to an omni-retailer media strategy with confidence.
