This case study details how Windsor.ai assisted Schroders, a global investment management company, in reducing their marketing cost per acquisition (CPA) by 41%. The document outlines the challenges faced by Schroders in analyzing customer journeys across multiple advertising channels, including AdWords, Social Media, Outbrain, Email, and Programmatic. The marketing team sought a method to analyze these journeys without bias or double-counting conversions. The solution implemented involved three key steps: first, onboarding all DoubleClick Campaign Manager and Google Analytics journey data onto the Windsor.ai Attribution Insights platform to understand user conversion across channels; second, integrating cost data from various sources via APIs with customer journey data; and third, applying a data-driven multi-touch attribution model to accurately calculate the true CPA. The case study concludes with Schroders' intention to continue decreasing CPA and expanding the Attribution Insights platform's use across APAC markets.
