> Google relies on duration of stay data from chrome and google analytics to rank search results
Has Google said this? They might infer duration from time between clicks on different search results, but I've never seen evidence they are using data from Chrome and Google Analytics.
On one hand I find it hard to believe they do not use it. It's not like it's buried in the analytics dashboard. It's a pretty prominent metric. However, I have gotten websites organically ranked that I never implemented an Analytics tag on.
Yes, Google has said this. The use of telemetry from Google Chrome has factored into SERPs as far back as 2010 (perhaps farther but that's when I became aware of it).
Ah yes, 13 year old information. Maybe it was true then, it is not now. Cutts had a known pattern of denying anything and everything about their ranking data until cornered (see his video with Harry Shum of Bing when they caught Bing stealing Google clicks), so I would recommend against using him as a source for almost anything these days.
Believe what you want, but apply some basic logic - why would they not use data they already have?
