Case Study: Manna achieves a 490% increase in Add-to-Cart clicks with VWO A/B Testing

How Manna Used A/B Testing To Increase Add-To-Cart Clicks

Manna is a Hungary-based online retailer of chemical-free, organic, handmade personal-care products that struggled with customer trust in markets like Germany. Using VWO’s A/B Testing platform, Manna set out to increase clicks on the Add to Cart CTA by adding third-party product test certification logos and internationally recognized payment icons to its product pages.

With VWO, Manna ran a three-way A/B test on more than 3,000 visitors (evenly split). Variation 1—featuring a prominent banner with payment icons and three certification logos—achieved an 11.26% Add to Cart click rate versus 8.73% for Variation 2 and 1.48% for the control. VWO’s experiment showed that combining payment reassurance with product-authenticity badges delivered the best results, producing the case’s reported uplift (up to a 490% increase in click rate).
