Outcome
Winner
Before
After
If shoppers see a cleaner two-column layout that separates filters from results, then they will use filters more and convert at a higher rate because the page feels more organized and easier to refine.
What We Changed
- Split desktop collection pages into a filter sidebar (up to 1/3 width) and product results (at least 2/3 width).
- Made the filters sticky as shoppers scroll.
- Added an option to hide the filters.
- Left the mobile layout unchanged.

- Add-to-cart rate, the metric the test targeted, rose 7.6%, a statistically significant result.
- Bounce rate fell 9.2%, in line with easier filtering keeping shoppers browsing.
- The test ran only 9 days, so the revenue figures may settle lower over time.
