Adding a banner that reminded shoppers of the current promo code lifted transactions by 9.98% on MeUndies product pages. Add to Bag clicks rose 10%. MeUndies ran the test during its Valentine's Day sale, and it was published as a VWO case study.

## Result

**+9.98% transactions**

- Transactions: +9.98%.
- Add to Bag clicks: +10%.

## Control

Product pages showed no reminder of the current promotion. Visitors from ads landed straight on them and could miss the sale.

## Variant

A promo banner on select product pages reminded visitors of the promo code they could use.

## Why it likely won (our reading)

- Ad traffic skipped the home page, where the sale was promoted, so many visitors never saw the offer.
- Seeing the discount at the point of decision gives a direct reason to buy now.
- A peak gift-buying period means shoppers were already primed for a deal.

## Caveats

The test ran during a Valentine's Day sale, so the lift may be smaller outside peak season. The source body text also gives 9.8% for transactions, and sample size and confidence were not shared.

## How to run this test

- Hypothesis: If we remind product-page visitors of the current promo code, then more of them will buy because visitors who land from ads will learn about the sale they missed.
- Primary metric: Transactions per visitor
- Guardrail: Average order value
- Guardrail: Gross margin per order
- Guardrail: Promo code usage rate
- Who should test it: Stores that run promotions and send paid traffic straight to product pages. It won't help much if you rarely run promos or your sale is already visible site-wide.
