Making the product benefits section interactive and adding a sticky add-to-cart button on mobile raised add-to-cart clicks by 20.20% and ecommerce conversion rate by 52%. ConvertPolo ran this test for hydrogen water bottle brand Evolv, and it was published as a VWO case study. Both changes shipped together, so the lift belongs to the pair.

## Result

**+52% conversion rate**

- Add-to-cart clicks: +20.20%.
- Ecommerce conversion rate: +52%.
- The two changes were tested as one variant, so neither can be credited alone.

## Control

The mobile product page had a static benefits section and an add-to-cart button that did not follow the shopper down the page.

## Variant

The benefits section became interactive, with points shoppers could tap to explore each feature, and the add-to-cart button became sticky.

## Why it likely won (our reading)

- Visitors on this site scrolled a lot but rarely engaged; tap-to-explore points gave them a reason to interact.
- A hydrogen water bottle needs explaining, and exploring features one at a time may make the value clearer.
- The sticky button meant the buy action was always in reach once a shopper was convinced.

## Caveats

The interactive benefits and the sticky button were bundled into one variant. No sample size or duration for this test was shared; results were judged with Bayesian statistics.

## How to run this test

- Hypothesis: If we turn our mobile benefits section into tap-to-explore points and make the add-to-cart button sticky, then more shoppers will buy because they understand the product better and can act right away.
- Primary metric: Mobile ecommerce conversion rate
- Guardrail: Add-to-cart rate
- Guardrail: Page load time
- Guardrail: Revenue per visitor
- Who should test it: Brands selling products with features that need explaining, on mobile-heavy traffic. If your product is simple or well known, an interactive section adds effort without much payoff.
