A live message next to the buy button showing how many people bought the product in the past week lifted value per session by 3.5% for Cornbread Hemp. Visually ran the test and published it as a case study.

## Result

**+3.5% value per session**

- Value per session: +3.5% for the variant.
- No conversion rate or order value breakdown was shared.
- No sample size or confidence level was shared.

## Control

Product pages with no purchase-count message near the buy button.

## Variant

A real-time message beside the buy button saying how many people had bought the product in the past week.

## Why it likely won (our reading)

- A recent purchase count is social proof: it shows other people trust the product.
- Placing it beside the buy button puts the reassurance where shoppers make the decision.
- For CBD products, where some shoppers are unsure, seeing others buy may ease doubts.

## Caveats

Vendor-reported result. Visually doesn't share the sample size, test length or statistical significance, and the figure comes from the vendor's own marketing.

## How to run this test

- Hypothesis: If we show how many people bought a product in the past week next to the buy button, then value per session will rise because recent social proof reassures hesitant shoppers.
- Primary metric: Value (revenue) per session
- Guardrail: Add-to-cart rate
- Guardrail: Conversion rate on low-volume products
- Who should test it: Stores with enough sales that weekly counts look healthy. On products that sell only a few units a week, a low number may hurt more than help, so consider a minimum before showing it.
