Jakub Tested Pattern #26: Cart Reminder And Recently Viewed
In this tightly triggered experiment, users who (1) did not complete a purchase and (2) visited a different product page saw a button in the top-right corner labeled “Don’t Forget Your Club.” Clicking this button resumed the checkout process at the point where they left off, without requiring the same information to be re-entered.

Melina Tested Pattern #41: Sticky Call To Action
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.

Melina Tested Pattern #41: Sticky Call To Action
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.

Niels Tested Pattern #41: Sticky Call To Action On Kenhub.com
In this beautiful test, the key change was the introduction of a larger call to action linking to a premium / upgrade screen. The call to action was placed on the left sidebar which was floating. This is a great example of providing visibility to important elements by making them persistent.
