    Pattern #1: Remove Coupon Fields
          
Was Tested
                    by
        
          Someone         
            
      
Variation B Was Insignificant
- 
                
Measured by completed transactions | p-val 0.6155043
 
In this experiment, a fully visible coupon field (A) was made less visible by turning it into a default collaped link (B). Clicking on the link caused the coupon field to appear.
Variation B Was Likely Worse
- 
                
Measured by completed transactions | p-val 0.06906723
 
                          
                          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.
Variation B Was Insignificant
- 
                
Measured by total revenue | p-val 0.087
 - 
                
Measured by completed sales | p-val 0.28780505
 
                          
                          In this simple experiment, a highly visible coupon field was replaced with a less visible (but clickable) link in the variation. Clicking on the link would show the coupon field. Impact on sales and revenue was measured.
Variation B Was Likely Better
- 
                
Measured by completed sales | p-val 0.20762012
 
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.
Variation B Was Better

VWO.com published this test which removed two coupon fields on a shopping cart: a gift card code and a special offer code.
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.
