A Compact Navigation Bar Redesign Makes No Clear Difference to Conversion Rate


If we redesign the navigation to take less space and read more clearly, then visitors will navigate more efficiently and engage with more pages because a cleaner structure helps them find products faster.
What We Changed
- Made the navigation bar more compact, so it takes less vertical space, especially on desktop.
- Grouped categories more clearly and made key links easier to see.
- Kept cart, search and account within easy reach.
- Kept the navigation consistent across desktop and mobile.

Key Learnings
- Across 31,434 visitors, conversion rate moved just 0.3%, within normal variation.
- Desktop leaned positive: conversion rate rose 23.9% and revenue per visitor 49.6% on 7,288 visitors.
- On mobile, conversion rate fell 4.7%, which cancelled out the desktop gain.
- The space savings were largest on desktop, which may explain where the gain showed up.
