On a furniture brand's side cart, shoppers frequently abandon or delay checkout on higher-priced items as they approach the checkout flow. This experiment tested whether adding real-time social validation inside the side cart could reduce purchase anxiety, create urgency, and drive higher checkout progression.
Hypothesis: If we display real-time social proof indicators inside the mobile side cart, shoppers will feel higher validation and heightened urgency on high-consideration items and will gain confidence and complete checkout at a higher rate.
What we A/B tested:
The winning variation: The “Purchased in the Last 24 Hours” badge won over both the control and the active-interest variation. Showing that other shoppers actually completed a purchase provided the necessary reassurance for higher-ticket items. In contrast, showing that people merely had the item in their cart failed to build enough trust, implying that completed sales matter much more than intent for considered purchases.
The impact:
- +9.3% revenue per visitor
- +4.7% purchase conversion
Takeaways:
- Present purchase volume for high-ticket items. Proof of actual transactions builds far more buyer confidence on expensive items than simply showing that others are browsing.
- Match the proof format to the specific source of buying hesitation. High-consideration products require more proof to pull hesitant shoppers across the finish line.
- Target bottom-of-funnel friction to trigger compounding revenue wins. Reassuring shoppers at the precise moment before checkout drives higher conversion and revenue per visitor without needing discounts or sacrificing average order value.
