Add-to-Cart Button on Mobile Collection Pages To Boost Purchase Convenience


IF we add a visible “Add to Cart” button on mobile collection cards THEN the add to cart rate will increase BECAUSE it will be more convenient for users to add to cart from the collection page instead of having to go into each product detail page.
What We Changed
- Added an “Add to Cart” button on collection pages.
- Displayed the button as a floating icon on each product card.
- Prompted variant selection and enabled add to cart from the collection pages.
