Case Study: Bonprix achieves 4.5X return on ad spend and boosts incremental sales with Facebook

bonprix - Customer Case Study

bonprix, a Hamburg-based fashion retailer with 32 million customers in 29 countries, aimed to boost online sales and determine the optimal mix of brand and direct-response Facebook ads to maximize return on ad spend.

Using Facebook’s multi-cell lift frequency test, bonprix compared lower-frequency (avg. 3) and higher-frequency (avg. 6) brand campaigns alongside direct-response ads and found that higher brand investment and frequency across the full customer journey drove stronger performance—delivering a 4.5× increase in ROAS, +4.3% incremental sales, +4.1% incremental conversions, and a 12.9% rise in new incremental buyers.
