Booking Also A/B Tests Icon Labels Replicating Google's Recent Experiment
It seems like Booking just completed running an experiment that is very similar to a recent one from Google. The experiment evaluated icons with labels in the top navigation against a control version with labels only. Whether they copied each other intentionally or not doesn't really matter. Actually, if they were inspired by each other's changes then that's a great thing. What I do want to bring your attention to is that this experiment replicated. That is, both experiment results from Booking and Google now have similar outcomes making navigation with icons and labels even stronger.

Labels With Icons
In this experiment, the variation showed navigation links with icons. A few days later we detected that this experiment completed and the variation was implemented. :)
