Adding similar-product recommendations to out-of-stock product pages lifted The Oodie's conversion rate by 9.5%. Visually ran this test with The Oodie, a loungewear brand, and published it as a Visually case study. Before, those pages only offered a notify-me button.

## Result

**+9.5% conversion rate**

- Conversion rate: +9.5% with recommendations on out-of-stock pages.
- The change gave shoppers a way to buy now instead of waiting.
- Sample size, duration and confidence level were not shared.

## Control

Out-of-stock product pages offered only a notify-me button.

## Variant

A block of similar products was added to out-of-stock pages, alongside the notify-me option.

## Why it likely won (our reading)

- An out-of-stock page with only a notify-me button is a dead end for anyone ready to buy today.
- Similar items keep shoppers on the site instead of sending them back to search or to a competitor.
- Many loungewear shoppers may be open to a close alternative in another print or style.

## Caveats

Visually reported this result in its own marketing case study. Sample size, test length and statistical confidence were not shared. The case study does not say whether the notify-me button stayed in the variant.

## How to run this test

- Hypothesis: If we show similar products on out-of-stock product pages, then conversion rate will rise because shoppers can buy an alternative instead of leaving.
- Primary metric: Conversion rate
- Guardrail: Notify-me sign-ups
- Guardrail: Revenue per visitor
- Guardrail: Exit rate from out-of-stock pages
- Who should test it: Stores with frequent stockouts and products that have close alternatives. It will help less if your products are unique or rarely sell out.
