Showing the compatible frame SKU on each cart line lifted Revant Optics' conversion rate by 3.9%. Visually ran this test with Revant Optics, a replacement lens brand, and published it as a Visually case study. The change confirmed in the cart that the lenses would fit.

## Result

**+3.9% conversion rate**

- Conversion rate: +3.9% with the compatible frame shown in the cart.
- A modest lift from a small text change on each cart line.
- Sample size, duration and confidence level were not shared.

## Control

The cart listed the lenses but did not say which frame they fit.

## Variant

Each cart line showed the SKU of the frame the lenses are compatible with.

## Why it likely won (our reading)

- Replacement lenses only work with the right frame. Seeing the match in the cart removes a last-minute doubt.
- Shoppers who worry about ordering the wrong part may leave to double-check. The SKU answers that on the spot.
- It may also cut wrong-fit orders, though the case study does not say so.

## Caveats

Visually reported this result in its own marketing case study. Sample size, test length and statistical confidence were not shared. A 3.9% lift is small enough that it could fall within normal noise without a large sample.

## How to run this test

- Hypothesis: If we show the compatible frame model on each cart line, then conversion rate will rise because shoppers can confirm the fit without leaving the cart.
- Primary metric: Conversion rate
- Guardrail: Cart abandonment rate
- Guardrail: Return rate for wrong fit
- Guardrail: Average order value
- Who should test it: Stores selling parts, refills or accessories that must match another product. It will do little where fit or compatibility is not a concern.
