A redesigned mobile "selling fast" badge on five selected products changed conversion rate by -0.9%, a result too small to call either way. Clean Commit ran this follow-up test for an anonymized Shopify store and published it in its A/B test library. The redesign did lift mobile order value, the problem it was built to fix.

## Result

**-0.9% conversion, flat**

- Conversion rate: -0.9%. Inconclusive: the original had only a 66.8% probability of being better.
- Revenue per visitor: +1.8%, also within normal variation.
- Average order value: +2.7% overall and +3.8% on mobile, the metric the redesign targeted.
- Orders: -1.4%, another small, inconclusive move.

## Control

The store without the "selling fast" badge.

## Variant

A "selling fast" badge sat on the product images of five selected products, with a new mobile design. The redesign followed an earlier version that had lowered mobile order value.

## Why it likely came out this way (our reading)

- A badge on only five products is unlikely to shift store-wide conversion much.
- The new mobile design may have removed whatever pulled shoppers toward cheaper items in the first version.
- Shoppers who have already seen urgency cues often learn to ignore them, which can blunt the effect over time.

## Caveats

95,695 visitors over 35 days, and none of the changes reached significance. Treat the order value gain as a hint, not proof.

## How to run this test

- Hypothesis: If we redesign the mobile "selling fast" badge, then mobile order value will recover without hurting conversion because the badge will no longer steer shoppers toward low-value items.
- Primary metric: Conversion rate
- Guardrail: Mobile average order value
- Guardrail: Revenue per visitor
- Guardrail: Orders
- Who should test it: Stores that already ran an urgency badge test and saw a device-specific problem. If the badge only covers a handful of products, expect small store-wide effects.
