Content

In this simple experiment on an article page, the variation slid out a sticky call to action linking to the next article. The sliding interaction triggered after some scrolling threshold (around 1000px or so). Afterwards, the sticky call to action maintained its floating position. The experiment measured clicks on this "next article" button.

Listing

In this experiment, a floating top navigation was shown with a "Join" button. In the control, the navigation was only visible at the top of the page. Also keep in mind that signup starts were also triggered throughout multiple CTAs throughout the page and from particular job detail pages. The a/b test ran on a listing page of Backstage - a casting call job site. Impact on signups  and checkouts was measured.

Product

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.

Product

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.

Content

In this experiment, the same message (with a link) for signing up to a newsletter was shown in two distinct ways. The control (A) showed the signup message as inline one that preceded the content of the article at the very top. The variant showed the same signup message as a scroll-delayed sticky interaction at the bottom of the screen. The background color of the B variant was also inverted to match the style of the footer.

Product

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.

For each pattern, we measure three key data points derived from related tests:

REPEATABILITY - this is a measure of how often a given pattern has generated a positive or negative effect. The higher this number, the more likely the pattern will continue to repeat.

SHALLOW MEDIAN - this is a median effect measured with low intent actions such as initiating the first step of a lengthier process

DEEP MEDIAN - this is derived from the highest intent metrics that we have for a given test such as fully completed signups or sales.
