This report shows the average time a user spends viewing any page on your SharePoint website, a specific page or website item, or a specific page and all of its child items. The widget filter preferences can also be edited to only report data from specific users or groups.
The meter widget simply displays the average time users spend per page, in seconds.
The chart widget displays the average view time in seconds, separated into blocks of time relevant to the time range filter. For example, if the time range selected is "Last Month," the widget will display the average page views per day. Similarly, if the time range selected is "Last Day," the chart will display the average duration per hour.
