Before
After
IF we introduce a top sticky Add to Cart bar with a size selector and preselection, THEN the add to cart rate will increase on PDPs, BECAUSE users can complete the purchase flow faster without needing to scroll back up or select sizes manually.
What We Changed
- Enhanced the visibility of the add-to-cart button by adding the sticky add-to-cart bar.
The Results
We dig through every data source to map what's actually broken. By the end, there's no confusion.
