Outcome
Inconclusive
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
Added the sticky add-to-cart bar with:
- Size selector dropdown (persistent in sticky bar)
- Color selector dropdown
- "Find my size" link for guidance

We dig through every data source to map what's actually broken. By the end, there's no confusion.
