Adding a compact Rebuy recommendation widget to Fame's Shopify Plus checkout showed a 2% conversion lift, but we treat the result as inconclusive. Revenue per visitor was flat at -0.16%, and only two products were bought through the widget. Blend Commerce ran the test in Rebuy across mobile and desktop.

## Result

**+2% conversion, inconclusive**

- Conversion rate: +2%. No confidence level was reported, so this may be noise.
- Revenue: +5% in total, but revenue per visitor: -0.16%. Per visitor, revenue was flat.
- Only two products were bought through the widget during the test. The cross-sell itself added very little.
- The main takeaway: the widget did not appear to hurt checkout. The agency rolled it out and planned follow-up tests.

## Control

Fame's Shopify Plus checkout had no product recommendations.

## Variant

A compact Rebuy widget in checkout showed complementary or recently viewed products, based on the shopper's cart and browsing.

## Why it likely came out this way (our reading)

- A compact module may stay out of the way, which would explain why checkout completion did not drop.
- Shoppers in checkout are focused on paying, so few stop to add another item.
- Checkout gets less traffic than other pages, which makes a clear result harder to reach in the same time.

## Caveats

Confidence and sample size were not reported, and Rebuy did not provide session data. With only two widget purchases, the result is directional at best.

## How to run this test

- Hypothesis: If we show a small set of relevant add-on products in checkout, then average order value will rise because shoppers see useful extras at the point of highest intent.
- Primary metric: Revenue per visitor
- Guardrail: Checkout completion rate
- Guardrail: Conversion rate
- Guardrail: Widget purchases
- Who should test it: Shopify Plus stores with clear add-on products, such as accessories or refills, and enough checkout traffic to reach a result. Stores with low checkout volume may wait weeks for a clear answer.
