Showing the percentage off next to the price on sale product cards moved conversion rate by just 1.0%, an inconclusive result. Clean Commit ran this test for a Shopify store and published it in its A/B test library. Across 8,260 visitors in 19 days, the variant had a 53.2% chance of beating the original.

## Result

**+1.0% CR, inconclusive**

- Conversion rate: +1.0%, with a 53.2% probability of beating the original. Inconclusive.
- Revenue per visitor: +7.5%, and average order value +6.4%, led by desktop. Both are within normal variation.
- Orders: +2.4%.
- Mobile conversion rate dipped 2.4%, so any effect may differ by device.

## Control

Sale items on collection pages showed their prices without stating the percentage discount.

## Variant

Sale items showed the percentage price reduction next to the price on the product card. Products not on sale were unchanged.

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

- The sale price was likely already visible as a markdown, so the percentage added little new information.
- Only sale items changed, so the share of traffic exposed to the new label was limited.
- Shoppers may judge a deal by the final price more than by the percentage.

## Caveats

The test ran 19 days on 8,260 visitors and did not reach significance. The revenue gains are within normal variation.

## How to run this test

- Hypothesis: If we show the percentage off on sale product cards, then more shoppers will click into and buy discounted items because the size of the saving is clear at a glance.
- Primary metric: Conversion rate
- Guardrail: Revenue per visitor
- Guardrail: Product card click-through rate
- Guardrail: Average order value
- Who should test it: Stores that run frequent or deep sales and whose collection pages mix sale and full-price items. It probably won't help if your markdowns are small or your sale prices already show a clear strike-through.
