A Wishlist on Product Cards and Product Pages Shows a 4.2% Conversion Rate Lift


If we let customers save products to a wishlist from collection and product pages, then conversion rate will increase because saving items encourages return visits and shortens the path to purchase.
What We Changed
- Added a heart icon to product cards on collection pages and to product pages.
- Saved wishlists to the account for logged-in customers.
- Prompted guests to log in or create an account to save items.
- Added a wishlist link in the header or account menu.
