Case Study: Dutch online seller Overtoom achieves 24% conversion lift with VWO A/B testing

How Dutch Online Seller Overtoom Increased Its Conversions Using VWO

Overtoom, part of the international Manutan Group, is a Dutch online seller of office supplies that wanted to increase Add to basket clicks on its product pages. To address this, Overtoom used VWO’s A/B testing platform to run experiments aimed at improving conversion rates.

Using VWO, Webshop Marketer Giuseppe Hentenaar tested a variation that placed three elements beneath the Add to Basket CTA—star ratings, a free‑shipping threshold for orders over €200, and visible payment options. The VWO-driven A/B test ran about 10 days and produced an almost 25% lift in conversions with 99.9% statistical significance.
