Google: User Experience As A Ranking Signal Is Currently Only For Mobile Results, Not Desktop Results
Google's desktop algorithm doesn't use web page user experience as a ranking signal - that is only a mobile ranking signal.
At SMX Sydney this morning, Google’s Gary Illyes explained that while user experience, aka UX, is a ranking signals on mobile with the Google mobile friendly algorithm but when it comes to desktop, there is no UX algorithm.
Gary said this at SMX Sydney and then confirmed it on Twitter saying there is mobile UX signals but on desktop there are none:

We know that the bulk of the Google mobile friendly algorithm is made up of how the web page renders on a mobile device. The mobile friendly update is purely about the user experience of your web site on a mobile device. But when it comes to desktop, Google currently doesn’t look at UX signals for ranking. That may change but for now, UX is not a direct ranking signal.
