Dwell Time:
This interesting metric refers to the amount of time a user spends on a webpage between the moment he clicked on the search engine result and the moment he hits the back button to go back to search results. A short dwell time can be associated with low satisfaction whereas a long dwell time can mean that the webpage satisfied the user’s needs. However, the opposite can be true as well, if somebody is looking for the weather forecasts for example, a short dwell time will be associated with satisfaction.
