Leak #85 from Etsy.com   |   Aug 16, 2022 Product

Etsy A/B Tests And Implements Required Field Labels

Here is a very tiny a/b test from Etsy - the marking of two product personalization fields as required using red asterisks. If I had to guess, I'd expect the effect on checkouts was probably very small if any (based on the pattern data so far). View Leak

+0.5 Evidence

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.
