This experiment replaced a visible coupon field with a dynamic text link that would initially hide the form field. Only after clicking the text link would the coupon form field appear. The translation from German is "Do you have a coupon code? Click here to apply". Impact on completed transactions was measured.

In this test the coupon field was replaced with a small link that would bring the field back if needed. This is a more suble approach than just completely removing the coupon field. It still allows for the use of coupon fields by those customers which are truly searching for a way to enter their aquired codes.

Related Patterns

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.
