Adding a larger Trustpilot widget with customer reviews just below the Add to Basket button lifted purchases by 58.29%. The agency High Position ran this A/B test for Express Watches, a UK authorized Seiko dealer, and it was published as a VWO case study. The test ran for over two months with thousands of visitors and reached 99% significance.

## Result

**+58.29% purchases**

- Purchases: +58.29% with the Trustpilot widget on product pages.
- Statistical significance: 99%.
- The test ran for over two months with thousands of visitors. The exact sample size was not shared.

## Control

Product pages showed a Seiko authorized-dealer badge, a small green Trustpilot badge and a list of reasons to buy from the store.

## Variant

A larger Trustpilot widget showing real customer reviews was placed right under the Add to Basket button, with a line above it saying customers love the store.

## Why it likely won (our reading)

- A user survey showed visitors worried about fake watches, and the site's own claims were not enough to settle that.
- Reviews hosted by an outside platform are harder to fake than testimonials a store writes on its own site.
- Placing the widget right below the buy button put the reassurance at the moment of decision.
- For a retailer that is not a famous name, independent proof helps it stand apart from replica sellers.

## Caveats

High Position has since been acquired by Semetrical. The test's date was not given, so the result may reflect an older market.

## How to run this test

- Hypothesis: If we show independent third-party reviews right under the add-to-cart button, then purchases will rise because shoppers will trust that we are a genuine seller.
- Primary metric: Purchases (orders per product page visitor)
- Guardrail: Add-to-cart rate
- Guardrail: Clicks away to the review site
- Guardrail: Average order value
- Who should test it: Lesser-known stores selling high-value or often-faked products, such as watches, electronics or luxury goods, where trust is the main barrier. It will matter less for big brands or if your third-party rating is weak.
