- Outcome: Won

Adding a dedicated Shop Pay button under the Checkout button in Fame's cart drawer lifted conversion rate by 47.75% and revenue per visitor by 69.30%. Blend Commerce ran this A/B/C test for the apparel brand on all devices using Intelligems. A version with payment icons instead also raised conversion but cut checkout starts.

## Result

**+47.75% conversion rate**

- Conversion rate: +47.75% for the Shop Pay variant against control.
- Revenue per visitor: +69.30%, the biggest gain in the test.
- Checkout begin rate: +19.33%, so more shoppers moved from cart to checkout.
- Average order value: +14.59%. Desktop gains were larger than mobile.
- The payment-icons variant improved conversion and order value but lowered checkout starts by 7%, a negative on that metric.

## Control

The cart drawer showed only the standard Checkout button.

## Variant

A Shop Pay button, the same size and style as Checkout, sat directly below it. A second variant showed payment method icons under Checkout instead, with no Shop Pay button.

## Why it likely won (our reading)

- A one-tap express route lets returning Shop Pay users skip typing their details.
- Matching the size of the Checkout button made the option clear rather than a small afterthought.
- Icons only reassure; a button gives a direct action, which may explain why icons cut checkout starts.

## Caveats

The source does not share sample size, test duration or a significance level. Gains this large are worth confirming with a retest on your own store.

## How to run this test

- Hypothesis: If we add a full-size Shop Pay button under Checkout in the cart drawer, then more shoppers will complete orders, because returning Shop Pay users can pay in one step.
- Primary metric: Conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Checkout begin rate
- Guardrail: Average order value
- Who should test it: Shopify stores with a cart drawer and a fair share of returning or mobile shoppers likely to have Shop Pay. It may do less on stores outside Shopify, or where most buyers pay by invoice or another method.
