Adding a one-tap quick-add cart icon to mobile product cards lowered conversion rate by 5.6%, though average order value rose 7.2% and revenue per visitor rose 2.9%. Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library. The result is mixed and not significant: fewer shoppers bought, but they spent more.

## Result

**-5.6% conversion, mixed**

- Conversion rate: -5.6%, a negative result. The original had a 79.3% probability of doing better, short of significance.
- Add-to-cart rate: -2.4%, a negative result, even though more adds were the goal.
- Orders: -5.0%, a negative result.
- Revenue per visitor: +2.9%, held up by average order value rising 7.2%.

## Control

Mobile product cards with no add button, so shoppers had to open the product page to add an item.

## Variant

A floating cart icon on each mobile product card that added the default variant in one tap, and asked for a size when one was needed.

## Why it likely came out this way (our reading)

- Skipping the product page means shoppers miss photos, reviews and details that help them commit.
- Shoppers who quick-add several items may build bigger baskets, which fits the higher order value.
- A size prompt on a small card can feel like an extra step, which may cancel out the shortcut.

## Caveats

Mixed and not significant: fewer buyers but larger orders. Sample size and duration were not shared.

## How to run this test

- Hypothesis: If we add a one-tap add-to-cart button to mobile product cards, then add-to-cart rate will rise because shoppers won't have to open each product page first.
- Primary metric: Conversion rate on mobile
- Guardrail: Average order value
- Guardrail: Revenue per visitor
- Guardrail: Add-to-cart rate
- Who should test it: Stores selling repeat-purchase or low-consideration items, where shoppers already know the product. Stores with products that need photos, sizing or reviews to sell may see conversion drop, as here.
