Key Learning
Problem: Users arriving at the mobile can't efficiently find what they're looking for, increasing bounce rates.
What was tried: The variant changed the existing experience but introduced unexpected friction. (-13.5% change)
Why it failed: Major layout changes often lose because they disrupt learned user behavior. Test smaller, incremental layout tweaks instead.
