Placing product-specific customer testimonials directly below the Add to Cart button lifted Supergut's conversion rate by up to 20.35%. Visually ran this test with Supergut, a gut health supplement brand, and published it as a Visually case study. The change lifted conversion on every product page tested.

## Result

**up to +20.35% conversion**

- Conversion rate: up to +20.35%, the best result across the product pages tested.
- Every product page in the test showed a lift, though the per-page figures were not shared.
- Sample size, duration and confidence level were not shared.

## Control

Product pages had no product-specific testimonials near the buy button.

## Variant

Customer testimonials written about that specific product sat directly below Add to Cart.

## Why it likely won (our reading)

- Supplement buyers want proof that a product works for people like them. Testimonials at the buy button answer that at the moment of decision.
- Product-specific quotes feel more relevant than generic brand praise.
- Shoppers no longer need to scroll down to the reviews section to find reassurance.

## Caveats

The 20.35% figure is the best result across several product pages, so a typical page likely gained less. Visually reported this result in its own marketing case study. Sample size, test length and statistical confidence were not shared.

## How to run this test

- Hypothesis: If we place product-specific testimonials directly below Add to Cart, then conversion rate will rise because shoppers see proof where they decide to buy.
- Primary metric: Conversion rate
- Guardrail: Add-to-cart rate
- Guardrail: Average order value
- Guardrail: Revenue per visitor
- Who should test it: Stores selling products where results matter, such as supplements or skincare, that have strong product-level testimonials. It will do less if you have few reviews per product.
