Adding Shop Pay, PayPal and Google Pay express buttons to Singular Sound's cart drawer lifted conversion rate by 35.44%. Blend Commerce ran this A/B test for the music equipment brand. Revenue per visitor rose 56.77% and products per visitor 38.89%.

## Result

**+35.44% conversion rate**

- Conversion rate: +35.44%.
- Revenue per visitor: +56.77%.
- Average products per visitor: +38.89%. Shoppers added more items before paying.
- Statistical significance: 95.89% over 13 days.

## Control

The cart drawer had only the standard checkout button. Shop Pay express checkout was offered on the product page only, which suited single-item purchases.

## Variant

Shop Pay, PayPal and Google Pay express checkout buttons were added inside the cart drawer, alongside the standard checkout.

## Why it likely won (our reading)

- Express checkout on the product page only works for one item. In the cart, it covers the whole basket.
- Familiar wallet buttons skip form filling, which cuts effort at the last step.
- Knowing a fast checkout waits in the cart may make shoppers more willing to add extra items.

## Caveats

The test ran for 13 days. Sample size was not shared.

## How to run this test

- Hypothesis: If we add express checkout buttons to the cart drawer, then more shoppers will complete purchases because they can pay for their whole basket in one step.
- Primary metric: Conversion rate
- Guardrail: Average order value
- Guardrail: Products per order
- Guardrail: Checkout completion rate
- Who should test it: Shopify-style stores with a cart drawer and express wallets offered only on product pages or at checkout. Less useful if your cart already shows express options.
