What is dwell time, and why isn't it a measurable metric?
Dwell time is defined as the time that passes between a user clicking a result on the search engine results page (SERP) and returning to that same results page. The logic behind the concept is easy to follow: if someone clicks a link, spends a good while on the page, then goes back to Google to search for something else, the content probably matched what they were looking for. If they come back within a few seconds, that suggests the page didn't meet their expectations.
Here's the point that needs to be clear from the start: Google doesn't publish dwell time as a figure, and there's no way to look it up in any standard analytics or Search Console tool. Google Analytics doesn't collect it, because Analytics only sees what happens on your own site: it has no way of knowing whether a user arrived from a Google search, or whether, after leaving, they returned to the SERP or simply closed the tab. Search Console doesn't measure it either: its reports cover clicks, impressions, CTR, and average position, none of which touch what a user does after clicking.
That's why dwell time is better described as a theoretical SEO concept than as a metric: it describes an idea about how a search engine might behave, not a number that exists in any system a marketer can access. Any article that shows a "dwell time figure," or promises to "increase your dwell time with these tactics," is at minimum oversimplifying.
