Reordering a mobile product customizer so shoppers typed their text first came with a 3.0% rise in conversion rate and a 21.7% rise in revenue per visitor. Clean Commit ran this test for an anonymized Shopify store selling hats and apparel. The variant had only a 62.0% probability of beating the original, so we treat the result as inconclusive.

## Result

**+3% conversion, inconclusive**

- Conversion rate: +3.0% overall, with a 62.0% probability of beating the original. That is close to a coin flip.
- Revenue per visitor: +21.7%, and average order value: +18.2%.
- Orders: +4.0%.
- Mobile conversion rate: +16.0%. Desktop conversion rate: -50.5%, but from only 526 desktop visitors.

## Control

The mobile customizer asked for the custom text later in the flow, and the add-to-cart button sat further from the quantity selector.

## Variant

The text input moved to the first step, the preview showed placeholder text before anyone typed, and add-to-cart moved up next to the quantity selector.

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

- Putting the personal text first gets shoppers invested in their design right away.
- Placeholder text in the preview shows what the finished product will look like before any effort.
- A button next to the quantity selector is easier to reach on a small screen.
- The desktop drop is based on too few visitors to read much into, and the change targeted mobile.

## Caveats

The test had 6,711 visitors and a 62.0% probability to beat control, so it is not statistically significant. Desktop results came from just 526 visitors. Duration was not shared.

## How to run this test

- Hypothesis: If we ask for the custom text first and show a placeholder preview, then mobile conversion rate will rise because the customizing flow feels clearer and the add-to-cart button is easier to reach.
- Primary metric: Mobile conversion rate
- Guardrail: Desktop conversion rate
- Guardrail: Average order value
- Who should test it: Stores selling personalized products through a step-by-step customizer, mostly on mobile. Stores without personalization have nothing here to test.
