Ninepine boosts revenue per visitor by 25% with Klarna

Ninepine is one of the most data-driven apparel brands in the Nordics, known for continuous A/B testing across its entire e-commerce experience, from site design to checkout and retention. The question was clear: could Klarna’s on-site messaging drive measurable gains in conversion and customer value within such a highly optimized, test-focused environment?

Ninepine integrated Klarna’s on-site messaging across five key markets: Sweden, Finland, Norway, Denmark, and the UK. By highlighting flexible payment options at product and checkout stages, the solution aimed to boost shopper confidence and reduce hesitation — especially at the point of purchase. The integration was seamless and aligned with Ninepine’s data-driven testing culture, enabling precise measurement of its impact on conversion, return per visitor, and average order value.

The results of implementing Klarna’s on-site messaging were striking across all five markets. Ninepine achieved a 25.3% increase in revenue per visitor (RPV), a lift driven by the combination of a 21.5% improvement in CVR and a 3.3% increase in AOV. Together, these results demonstrate how Klarna’s solution not only encouraged more customers to complete their purchases but also increased the value of each transaction, delivering a powerful and measurable impact on overall revenue efficiency.
