No Coupon Fields
  1. Remove: Coupon Fields Fewer Form Fields

    Remove the discount, coupon or promo code altogether. It makes people (without coupon codes) second guess themselves why they might not have received a coupon. Some people might also leave searching for coupon codes, never to come back and finish the purchase.

It Likely Worked Here

+0.5 Repeatability Checkout

  • Measured by completed sales   |   p-val 0.207383

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.

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.
