Viljo Tested Pattern #62: Urgent Next Day Delivery On Bobandlush.com

 - Variant A
 - Variant B

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.
