Compatible frame shown on each cart line: +3.9% conversion rate
Test run byVisuallyTesting and CRO tool
Commentary byLiftArchiveOur analysis, not theirsShowing 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.
- 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.
The change
Each cart line names the frame the lenses fit
Simplified mockup drawn by LiftArchive from the shared screenshots.
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 of the result, not the practitioner's claim.
- 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 on your store
- 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
- Guardrails
- Cart abandonment rate
- Return rate for wrong fit
- 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.
Questions
Should the cart show product compatibility details?
For fit-specific items it can help. Revant Optics saw a 3.9% conversion lift from adding the compatible frame SKU to cart lines.
What compatibility details belong in the cart?
Keep it to the one fact shoppers worry about, such as the model it fits. Too much text can clutter the cart.
Does this reduce returns?
It might, since buyers can catch a mismatch before paying.
Revant Optics did not share return data, so track it as a guardrail.
