I knew this Martin Splitt laptop head-bang GIF would come in handy the day he would answer this question. Many Googlers have said over the years that user actions, such as dwell time, time on a page, and so forth at not used by Google as a search ranking factor. Martin Splitt from Google has now also said it (he may have said it before, but I never saw it).
He was asked "Does Google (Search Algorithm) use UX (such as dwelling time/time on page, etc.) as a ranking factor? If so, how Google get the data? Does it use Google Analytics data or something else?" Martin responded "We're not using such metrics."
Here are those tweets:
