Reworking Sparify's mobile performance parts product pages with a stronger hierarchy, bigger images, clearer offers and more social proof lifted add-to-cart rate by 6.25%. ConvertPolo ran this test for Sparify, a motorcycle gear and parts store, and it was published as a VWO case study. Several changes shipped together, so the result can't be pinned on any one of them.

## Result

**+6.25% ATC**

- Add-to-cart rate: +6.25% on mobile.
- Coupon box interactions: +123.74%. Far more shoppers noticed and used the offer.
- No revenue or order figure was shared for this test, so we can't say whether the extra coupon use cut into margin.
- This was a bundled change, so the lift belongs to the package.

## Control

Performance parts pages underplayed the product's value. Benefits, promotional offers and trust signals were there but lacked emphasis.

## Variant

The page used a stronger visual hierarchy, more prominent imagery, clearer offer messaging and more social proof to make the value obvious at a glance.

## Why it likely won (our reading)

- Performance parts are a considered buy. Making benefits easy to spot helps shoppers justify the price.
- Clearer offer messaging gives a reason to buy now, which the jump in coupon use reflects.
- More visible social proof reduces doubt about fit and quality.

## Caveats

Several changes shipped together, so the result can't be credited to one element. Mobile only, with no sample size, duration or confidence level shared.

## How to run this test

- Hypothesis: If we make benefits, offers and reviews more prominent on our product pages, then more shoppers will add to cart because the product's value is clear at a glance.
- Primary metric: Add-to-cart rate on product pages
- Guardrail: Revenue per visitor
- Guardrail: Average discount per order
- Guardrail: Conversion rate
- Who should test it: Stores selling higher-priced or technical items where value needs explaining. Watch margin if your offers become more visible, and expect less if your pages already lead with benefits.
