Case Study: Pom Pom London boosts iROAS by 94% with Bark.London’s Meta Incremental Attribution

Pom Pom London boosts iROAS by 94% with Bark.London

Pom Pom London, a global retailer of bags and accessories, partnered with performance marketing vendor Bark.London. Their challenge was that Meta’s default attribution settings did not accurately reflect the true business impact of their advertising efforts, particularly for campaigns targeting new customers. This made it difficult to optimize their ad spend for genuine, incremental growth.

Bark.London implemented a test of Meta’s new Incremental Attribution beta setting, using a conversion lift study and Meta's Robyn modeling framework to measure true impact. The solution provided a more accurate picture of which ads were driving real value. As a result, Bark.London boosted Pom Pom London's incremental return on ad spend (iROAS) by 94%, uncovering significant new opportunities for profitable growth and channel diversification.
