Case Study: Trendday.dk achieves 51% revenue growth and 9.5X return on ad spend with Facebook

Trendday.dk - Customer Case Study

Trendday.dk is a Danish online fashion retailer founded by Camilla and Kasper that sells affordable women’s fashion to customers in eight European markets. After establishing the brand, their challenge was to keep acquisition costs low while continuing to find new customers and drive more online sales among their core 16–29 female audience.

They partnered with an agency and used Facebook tools—lookalike audiences, carousel and video ads, split-tested creative with Power Editor, and dynamic ads plus website Custom Audiences—to re-engage visitors and show personalized products. The campaign delivered 10 million impressions, became their number-one marketing channel, achieved a 9.5x return on ad spend and grew revenues by 51% over five months.
