Blend Commerce ran this A/B test. Conversion rate rose 21.39% and average order value 60.66%.
- Revenue per visitor: +95.34%.
- Conversion rate: +21.39%, and add-to-cart rate: +34.01%.

The change
Filter and sort controls stay pinned on mobile instead of scrolling away.
Simplified mockup drawn by LiftArchive from the shared screenshots.
Control
On mobile collection pages, the filter and sort controls scrolled away. Shoppers had to scroll back up to refine the list.
Variant
A sticky filter and sort bar stayed at the top of the screen while shoppers browsed mobile collection pages.
Why it likely won
Our reading of the result, not the practitioner's claim.
- Heatmaps showed mobile shoppers going back to the filters again and again. Keeping them in reach saved that effort.
- Grills are a considered purchase where buyers compare specs and price, so easy filtering matters more.
- Better filtering may have helped shoppers find higher-priced products that matched their needs, which fits the jump in order value.
Caveats: No significance level, sample size or duration was shared. A 60% jump in order value on a small sample can come from a few large orders.

How to run this test on your store
- Hypothesis
- If we make the filter and sort bar sticky on mobile collection pages, then revenue per visitor will rise because shoppers can refine the list at any time.
- Primary metric
- Revenue per visitor
- Guardrails
- Conversion rate
- Filter use rate
- Mobile scroll depth
- Who should test it
- Stores with large catalogues and high-consideration products where shoppers compare specs. Small catalogues with few filters will likely see little change.
Questions
Should filters be sticky on mobile collection pages?
If shoppers use filters often, it is worth testing.
BBQ Land saw revenue per visitor almost double.
How do I know if my shoppers need easier filtering?
Check heatmaps or click data for repeated scrolls back to the filter controls.
Frequent use suggests making them easier to reach.
