In this experiment, a password field was removed on a contract cancellation form (Volders).

In the control version, users were required to enter their email address and a password. If the email address was associated with an existing account, then the password was used to authenticate the user (and validated). When users entered a new email address, then the password field was used to create a new account. 

In the variation, the password field was removed, as the authentication happened after the conversion itself using other backend mechanisms.

Booking A/B Tested 3 Search Bars Challenging The Fewer Form Fields Pattern

A - Feb 4, 2019
B - Feb 4, 2019
C - Feb 4, 2019 IMPLEMENTED

I've been watching this Booking experiment closely ever since sharing a very similar concept some months ago. Their homepage was openly challenged with the UI hypothesis of exposing a "room quantity" field right in the search bar (instead of hiding it in a pulldown menu). And their team took the initiative to run a test. Based on the observed outcome and roll out decision it turns out that the UI concept was better than their control. View Leak

Booking Discovers That Two Search Bars Are Not Better Than One

A - Jan 13, 2020 IMPLEMENTED
B - Jan 13, 2020

In this experiment Booking added a second search bar on their homepage. The intention might have been to provide users a way to filter more destinations by country. Could this scenario have created an akward uncertainty about which form field to engage with? Whether this explanation is true or not, I'm not sure. What we do know however that in the end, the control version with the single search bar prevailed.  View Leak

Netflix A/B Tests Displaying A Password Field Which Fails And Gets Rejected

A - Mar 31, 2020
B - Mar 31, 2020 REJECTED

It looks like Netflix has been iterating on showing additional fields upfront on their homepage. After they succeeded at displaying an email address upfront, this experiment now takes next step of showing a password field. The result of the leaked experiment however suggests a negative outcome as they reverted back to the control version - without the visible password. 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.
