Homepage: Recently Viewed Products for Returning Users
Hypothesis
Showing returning visitors recently viewed products on the homepage will reduce re-discovery friction and increase purchase intent.
Test Results
Key Learning
Problem: Friction during the homepage process causes users to abandon right when they're closest to converting.
What worked: Recently viewed products reduce browse-and-return friction. Modest but reliable lift for returning users who already expressed interest. Best implemented as a personalized section below the fold rather than replacing the main hero. (+3.0% lift)
Takeaway: Even small lifts compound — across thousands of sessions, this adds up. Use this win as a foundation for further iteration on adjacent elements.
