This case study outlines how Moss, a UK retailer, significantly improved its return on ad spend (ROAS) by leveraging advocacy insights. The document details Moss's strategy of creating lookalike audiences based on unique advocacy data, which led to a 90% increase in ROAS, a 61% increase in conversions, and a 275% increase in conversion rate (CvR).
