Promo-code banner on product pages: +9.98% transactions
Commentary byLiftArchiveOur analysis, not theirsAdding 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.
- Transactions: +9.98%.
- Add to Bag clicks: +10%.
The change
The variant adds a banner reminding visitors of the promo code.
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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
- Guardrails
- Average order value
- Gross margin per order
- 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.
Questions
Should I show promo codes on product pages?
If a sale is running and visitors land on product pages from ads, a reminder can help. MeUndies saw transactions rise almost 10%.
Will showing a promo code hurt margins?
It can, since more people use the code. Track margin per order alongside transactions.
