Test #444 on by Melina HessMelina Hess Nov 30, 2022 Mobile Product

Melina Tested Pattern #41: Sticky Call To Action

 - Variant A
 - Variant B

In this experiment, a floating add-to-cart with two product choices (color and size) were added on a product page. This appeared only after scrolling past the existing / embedded product selection buy box.

The floating add-to-cart widget had another layer of complexity in that it allowed customers to make a size and color selection with an expandable fly out. Making a selection would also append the total price to the add-to-cart button label.

Impact on total transactions was measured.

Test #441 on by Melina HessMelina Hess Nov 23, 2022 Desktop Mobile Product

Melina Tested Pattern #41: Sticky Call To Action

 - Variant A
 - Variant B

In this experiment, a floating sticky bar was added on product pages. The sticky elements only appeared after users scrolled beyond the fixed buy box  area that is relatively high on the page (visible on the control screenshot). The sticky bar contained three elements: a button to configure up to three product choices, a flavor selection pulldown, and the add-to-cart button. 

In the variation, when users clicked on the flavor pulldown three things happened. First, they were anchored back to the top of the buy box. Second, the floating sticky disappeared. And third, the flavors pulldown automatically expanded (overlapping the original primary add-to-cart button).

The control did not have any of the sticky behaviors.

Impact to total sales was measured.
