A subtle low-stock line below the add-to-cart button, showing how many units were left, lifted conversion rate by 22% on bestseller pages. Visually ran this test with London womenswear brand Odd Muse and published it as a case study. A more aggressive urgency version was tried first and did poorly, so the team toned it down to suit a premium brand.

## Result

**+22% conversion rate**

- Conversion rate: +22% for the subtle stock line on bestseller pages.
- An earlier, more aggressive urgency version performed poorly. Its numbers were not given.
- Sample size, test length and confidence were not shared.

## Control

Bestseller product pages showed no stock messaging.

## Variant

A small, factual line below the add-to-cart button showed how many units were left.

## Why it likely won (our reading)

- A factual count gives a real reason to buy now without feeling pushy.
- Loud urgency can feel cheap on a premium brand. A quiet line fits the tone.
- Placing it right below the button puts it where the decision is made.

## Caveats

The earlier aggressive version's results were not shared. Reported in a vendor case study without sample size, duration or significance.

## How to run this test

- Hypothesis: If we show a quiet, factual low-stock count below the add-to-cart button, then more shoppers will buy because they see a true reason not to wait.
- Primary metric: Product page conversion rate
- Guardrail: Return rate
- Guardrail: Repeat visit rate
- Guardrail: Conversion on pages without low stock
- Who should test it: Premium or fashion brands with limited stock on popular items. Only show real stock counts; fake scarcity damages trust and may break consumer law.
