Show Review Social Proof During Checkout

The checkout page has the highest-intent traffic on your store — and the highest abandonment rate. Adding subtle review social proof at this stage reinforces the purchase decision when doubt is most likely to creep in. A small "4.8 stars from 2,300+ reviews" badge near the order summary is enough.

The key is subtlety. The checkout page should not be cluttered with full review widgets. A compact trust badge, a single highlighted review quote, or a simple star rating next to each product in the cart provides reassurance without distraction. The shopper has already decided to buy — you just need to prevent them from second-guessing.

For Shopify stores, checkout customization is available through checkout extensions. Add a review trust badge that dynamically shows the aggregate rating for items in the cart. For multi-product orders, showing that each item is highly rated builds confidence across the entire purchase.

Test the placement carefully. Review social proof near the payment button tends to perform best because that is the highest-anxiety moment. A/B test with and without the badge to measure its impact on checkout completion rate.
