Taller Product Images and New Carousel Controls Show a 4.7% Conversion Rate Lift


If we modernize the image carousel on product pages, then add-to-cart rate will increase because a better visual experience makes it easier to evaluate products and act.
What We Changed
- Made the product image area taller.
- Replaced the carousel controls with minimal arrows and dot indicators.
- Added swipe support for moving between images.

Key Learnings
- Conversion rate rose 4.7% and orders 4.6% on mobile. Neither reached significance, so this is a signal, not proof.
- Add-to-cart rate, the metric the test targeted, was flat (-0.5%), with a 45.1% probability of beating the original.
- Revenue per visitor rose 3.2%, a smaller gain as average order value dipped 1.4%.
- Bigger images didn't change how often shoppers added to cart, though more of those carts may have become orders.
