Hypothesis - Urgency leads to higher conversions as people have less time to think and will instead follow their impulse to complete the purchase now rather than later.

The Treatment - From Monday to Friday, before 4 PM, we added the urgency message “Free next business day delivery if you order before 4 PM (UK)”. We placed the urgency message just below the product name ensuring that it fell into the reading pattern of all visitors interested in the products. To ensure the treatment was only shown at the right time and for the right people we added a condition: MON, TUE, WED, THU, FRI before 4 PM; UK IP.

This test duplicated two buttons at the bottom of the page. However, the site already contained floating buttons (from the header).

The test was run on multiple course pages. The screenshot contains the cropped bottom part of a long screen with an exposed signup form. The variation introduced additional text above the form which states: "Free Cancellation. Payment is not required today".

In this test an additional "Purchase" button was shown along side a "Learn More" button. The "Purchase" button went straight to checkout, whereas the "Learn More" button went to a product overview page.

This test was run on a 3 step checkout process. The first screen was asking for contact information, and the second screen asked for credit card details. The change was shown on both first two steps as shown on the image below.

De Nieuwe Zaak (a Dutch ecommerce agency) tested a countdown timer on an ecommerce site. The variation showed how many hours and minutes were left in order to be eligible for next day delivery. The variation beat the control which did not have this element of urgency.

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.

In 2012 a Microsoft employee working on Bing had an idea about changing the way the search engine displayed ad headlines. Developing it wouldn’t require much effort—just a few days of an engineer’s time—but it was one of hundreds of ideas proposed, and the program managers deemed it a low priority. So it languished for more than six months, until an engineer, who saw that the cost of writing the code for it would be small, launched a simple online controlled experiment—an A/B test—to assess its impact. Within hours the new headline variation was producing abnormally high revenue, triggering a “too good to be true” alert.

Note: This experiment was a solid success and replicated multiple times over a period of months. It worked at Bing and had a profound influence. The only reason why we atributed a 0.25 point (a "Maybe") was because we don't have the exact sample size and conversion data.

In this test, a footer with a button to a lead form was turned into a floating one.
