Widening the desktop collection page lifted product click-through rate 4.0% but cut conversion rate 5.9% and revenue per visitor 6.1%. Clean Commit ran this test for an anonymized Shopify store and published it in its A/B test library. The test was set up to measure clicks, and judging it on clicks alone would have shipped a change that lost sales.

## Result

**+4.0% clicks, -5.9% conversion**

- Click-through rate: +4.0%, a statistically significant gain on the test's main metric.
- Conversion rate: -5.9%. Negative.
- Orders: -8.0% and revenue per visitor -6.1%. Negative.
- Bounce rate fell 11.8% and add-to-cart rate fell 2.1%, so more engagement didn't turn into purchases.

## Control

Desktop collection pages used the original, narrower container width.

## Variant

The main desktop container was made wider and the product grid spacing adjusted to fit. Sidebar filters stayed visible, and tablet and mobile were unchanged.

## Why it likely lost (our reading)

- Bigger, more spread-out product cards may have invited more browsing clicks without making shoppers more sure of what to buy.
- A wider grid can make it harder to compare products at a glance.
- The source didn't report significance for the sales drop, so part of it may be noise.

## Caveats

The source shared no sample size or duration, and only the click-through gain was reported as significant. The change applied to desktop only.

## How to run this test

- Hypothesis: If we widen the desktop collection page, then more shoppers will click and buy because product images are easier to see with less clutter.
- Primary metric: Desktop revenue per visitor
- Guardrail: Product card click-through rate
- Guardrail: Desktop conversion rate
- Guardrail: Add-to-cart rate
- Who should test it: Stores whose desktop collection pages feel cramped on large screens. Choose sales as the main metric, since this test shows clicks can rise while revenue falls.
