Making product images larger on category pages and showing the description only on mouseover lifted revenue by 9.46% for Mall.cz. The agency Optimics ran the test, and it was published as a VWO case study. The tool gave this variant a 96% chance to beat the original.

## Result

**+9.46% revenue**

- Revenue: +9.46% for the larger-image, text-on-hover variant.
- Confidence: a 96% chance to beat the original, as reported by the testing tool.
- The result for the larger-image variant that kept the visible text was not shared.

## Control

The category listing showed product images at their original size, with a text description next to each one.

## Variant

Two variants ran. One used larger images with the text still shown; the other used larger images and revealed the description only when a shopper hovered over the product.

## Why it likely won (our reading)

- Bigger images let shoppers judge the product at a glance, which is often how people scan a category page.
- Hiding the text until hover cleans up the grid, so the images stand out more.
- Shoppers who want details can still get them by hovering, so little information is lost.

## Caveats

This was a three-way test, and the plain larger-image result was not published. Mouseover only works on desktop, and sample size and duration were not shared.

## How to run this test

- Hypothesis: If we enlarge product images on category pages and show descriptions only on hover, then revenue will rise, because shoppers can judge products visually and the grid is less cluttered.
- Primary metric: Revenue per visitor
- Guardrail: Click-through from category to product page
- Guardrail: Conversion rate
- Guardrail: Products viewed per session
- Who should test it: Stores selling visual products where looks drive the choice, with a lot of desktop traffic. It fits less well for spec-driven products, and hover text needs a different approach on mobile.
