Discover UI Design Decisions Of Leading Companies,
From Leaked Screenshots & A/B Tests.

This leaked experiment captures a very simple and isolated change on Booking's apartment landing page. The tested change was the automatic exposure of the calendar menu instead of keeping it collapsed (requiring an extra click to open the date picker). A few weeks later, the experiment was observed to have been completed with the exposed calendar version (B) as implemented. View Leak

Netflix has been yet again noticed experimenting with a range of variations on their homepage - all of which yet again seem to have been rejected as before. Below is the leaked experiment with its key changes, the decision, as well as our own followup experiment recommendation (if we had the privilege of doing so).  View Leak

It's now clear that Booking ran somewhat of a larger leap experiment of two very diverse search layouts on their Apartments landing page. I'm glad we discovered this one as we now know for sure their awesome team doesn't only run microscopic single change experiments. View Leak

I especially like this particular leak because there is a slight possibility I might have actually inspired Booking to a/b test it - how cool is that? In late November of 2018 I shared some search concepts, one of which suggested incremental UI controls for Booking's guest selector. View Leak

In this leak, three Airbnb property page screenshots with different time frames have been compared. Having done this, it became clear that at least one design decision was made near the bottom of the screen - further confirmed by the final screenshot. View Leak
