A follow-up test redesigned the mobile version of a selling fast badge shown on selected products. See how 95,695 visitors responded over 35 days.
Redesigned Selling Fast Badge Makes No Clear Difference to Conversion Rate


If we draw attention to selected products with a selling fast badge, then more shoppers will click through to those products because the badge creates a fear of missing out.
What We Changed
- Showed a selling fast badge on the product images of five selected products.
- Redesigned the mobile badge after an earlier version lowered mobile average order value.
- Kept the badge as a store setting so it can push older stock or products already selling well.
The Results
How the new version compared with the original, across all devices.

Key Learnings
- Conversion rate, the main metric, fell 0.9%, and the original had only a 66.8% probability of performing better.
- On mobile, average order value rose 3.8%, the metric the redesign set out to fix.
- Revenue per visitor rose 1.8%, but every shift stayed within normal variation across 95,695 visitors.
- A badge on a handful of products had little effect on store-wide conversion.
