Keeping the filter and sort bar fixed on mobile collection pages lifted revenue per visitor by 95.34% for BBQ Land. Blend Commerce ran this A/B test. Conversion rate rose 21.39% and average order value 60.66%.

## Result

**+95% revenue per visitor**

- Revenue per visitor: +95.34%.
- Conversion rate: +21.39%, and add-to-cart rate: +34.01%.
- Average order value: +60.66%, so shoppers bought pricier items.
- Filter and sort clicks: +10.45%, and product page view rate: +2.02%.

## 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)

- 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

- 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
- Guardrail: Conversion rate
- Guardrail: Filter use rate
- Guardrail: 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.
