From A/B Testing to Structural Growth: Personalization at Studio Anneloes

How do you make personalization measurable and scalable?

Studio Anneloes has been successfully working with Tweakwise for years, using A/B testing as the foundation for data-driven merchandising. In this session, we show how personalization on listing pages is structurally tested and optimized across all relevant KPIs: conversion rate, revenue, AOV, and UPT.

Through concrete experiments, you’ll discover why higher conversion does not automatically mean better overall performance. We share insights from tests comparing personalization versus generic listings, content positioning, and popular filter values.

A must-visit session for e-commerce managers and merchandisers who want to evolve from isolated experiments to a structural optimization strategy.
