Challenges
Low Engagement on a High-Impact Surface
Zalando’s PDP contained valuable product information, but low engagement with this content limited its impact on purchasing decisions.
Have a Similar Problem?
Let’s optimize your core product experiences for measurable growth.
Low engagement baseline
Only 5% of users opened product information sections, leaving most customers without key decision-making details.
High-risk experimentation
Changes to a high-traffic page required careful testing to avoid negative impact on conversion and GMV.
Concurrent experiments
Multiple experiments required isolation to prevent overlapping effects and ensure accurate measurement.
Unclear conversion link
Connecting engagement improvements to actual GMV impact required a robust measurement strategy.
