Pinning the Pump Finder tool as a sticky button on mobile collection pages lifted conversion rate by 69.25% for Aeromotive, an automotive parts brand. Blend Commerce ran this 13-day A/B test, which reached 97.4% significance. Cart completion rose 42.8%.

## Result

**+69% conversion**

- Conversion rate: +69.25%.
- Cart completion: +42.8%.
- Revenue per visitor: +18.72%, and total revenue +15.4%.
- Average order value: +13.4%.
- Products viewed per visitor fell 37.76%, so shoppers browsed less and bought more directly.

## Control

The standard mobile collection page did not make the Pump Finder tool prominent.

## Variant

The Pump Finder was pinned as a sticky button that stayed in reach as shoppers scrolled mobile collection pages.

## Why it likely won (our reading)

- Fuel pump buyers need a part that fits their vehicle. A finder answers that question quickly.
- About 60% of visitors were on mobile, where long collection pages make it hard to compare parts.
- A sticky, thumb-reachable button keeps the finder available wherever the shopper is on the page.

## Caveats

The test ran for 13 days, which is short. Sample size was not shared, and lifts this large often shrink over time.

## How to run this test

- Hypothesis: If we pin our product finder as a sticky button on mobile collection pages, then conversion will rise because shoppers can confirm fit without scrolling through products.
- Primary metric: Conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Finder completion rate
- Guardrail: Returns for wrong fit
- Who should test it: Stores that already have a finder or quiz and sell products where fit matters, such as parts, sizing or compatibility. Without a good finder tool behind the button, there is nothing to promote.
