Case Study: Winkelstraat.nl achieves 44% stronger ROAS with Billy Grace

How Winkelstraat.nl Scaled Smarter

Winkelstraat.nl, a leading online fashion platform, was looking to better understand the true performance of its expanded marketing efforts across multiple digital channels. Together with its agency, IWB, the customer sought to move beyond assumptions and manual processes to identify the real contribution of each platform to sales. This lack of clarity meant high-potential channels were underutilized. They partnered with Billy Grace to gain smarter use of their data for more efficient scaling.

By implementing Billy Grace's UMM attribution model and Autopilot automation, the vendor provided clarity on the full-funnel impact of each channel. This gave the team the confidence to scale underused platforms like Snapchat and TikTok while automating bidding and budget allocation. Billy Grace's solution helped Winkelstraat.nl achieve a 44% stronger blended ROAS, an 11.7% YoY ROAS growth, an 18% reduction in CPA, and an 80% reduction in time spent managing bids.
