Swapping the positions of the call-to-action button and a testimonial bubble in the homepage hero lifted sales by 35.6%. Underwater Audio, a seller of waterproof audio products, ran this A/B test itself, and it was published as a VWO case study. The swap also uncovered the main product image, which the testimonial had partly hidden.

## Result

**+35.6% sales**

- Sales: +35.6% for the swapped layout.
- Sample size, test length and statistical significance were not shared.

## Control

The homepage hero showed the title, then the CTA button, with a testimonial bubble below it that partly covered the product image.

## Variant

The CTA button and testimonial bubble switched places, so the hero read title, then customer quote, then button, and the product image was easier to see.

## Why it likely won (our reading)

- Visitors met the customer quote before the button, so they saw social proof right before being asked to act.
- The product image was no longer covered, so people could see what they were buying.
- In the original, visitors who clicked the button straight away likely never read the testimonial.
- Two changes came with one move, a new order and a clearer image, so it is hard to say which mattered more.

## Caveats

No sample size, duration or significance was given. Moving the bubble changed both the reading order and how much of the product image showed.

## How to run this test

- Hypothesis: If we place a short customer quote between the hero headline and the button, then sales will rise because visitors will see proof just before they are asked to act.
- Primary metric: Sales (orders per visitor)
- Guardrail: Hero CTA click rate
- Guardrail: Bounce rate
- Guardrail: Revenue per visitor
- Who should test it: Stores whose homepage hero sells one main product and has a strong customer quote to use. It is less likely to help if your hero is a broad brand banner or the quote is weak or generic.
