Case Study: Wonderbly achieves 18.1% uplift in orders with Optimizely

How testing & optimization has driven data-led decision making a for a dedicated online-only retailer

Wonderbly, the online-only retailer of personalized children’s books, wanted to improve its digital experience and increase conversion by using data to guide visitor journeys. Working with Optimizely, the company expanded its optimization efforts to better understand what would move shoppers through the funnel and support critical decision-making.

Optimizely helped Wonderbly run more than 50 A/B tests, including an experiment targeting customers with three-letter names for personalized books. A follow-up test on that segment showed the hypothesis was right, delivering an 18.1% uplift in orders for visitors arriving via Facebook ads. This result demonstrated the value of Optimizely’s experimentation approach for driving measurable business impact.
