  • Posted to Booking.com Just A/B Tested And Leaked This Pulldown Menu UI Change, Mar 26, 2019

    Instead of using 2 layered pulldowns, they decided to go with incremental controls (think small "+" and "-" buttons). Although we don't have access to the actual experiment, from this leak we still learned some critical things:

    1. it was a/b tested (since we have varying screenshots from the same day)
    2. the decision (weeks later after initial detection)

    We can learn a lot from companies that are running experiments ...

    Awesome work! We have 4 test results in favor of this pattern over at https://goodui.org/patterns/41/ - predicting a positive outcome. :) I would love to include your test result to strengthen the predictive power of this pattern even further.

    Facebook is known to run countless online experiments – most of which are kept secret. Luckily for us we have the Internet Archive that allows us to pry into these possible design optimizations.
