In SiteCatalyst 14, if a visitor spent 00:01:15 on a Web page, the reported Time Spent on Page metric would be 00:02:00.
The midpoint value of the 1 to 3 minute range.
Adobe Analytics/SiteCatalyst 15 uses explicit values (including link events and video views) to calculate Time Spent, so the reported Time Spent on Page value in this example would be 00:01:15.
The following table describes the differences in how Time Spent is calculated:
|SiteCatalyst 14||Adobe Analytics/SiteCatalyst 15|
|Time Stamp: Calculates a visitor's Time Spent value based on Web beacon time stamps generated by the visitor's page views.||Time Stamp + Link Event: Calculates a visitor's Time Spent value based on Web beacon time stamps generated by the visitor's page views and link events (custom, download, exit, and video).|
|Ranged Values: Reports Time Spent metrics using a midpoint value based on ten time buckets (or ranges), such as 30 to 60 seconds, 1 to 3 minutes, and 5 to 10 minutes.||Explicit Values: Reports the explicit Time Spent value, eliminating the use of midpoint values and time buckets.|
|Midpoint Average: Calculates average Time Spent metrics using the midpoint values rather than the explicit Time Spent values.||Explicit Average: Calculates average Time Spent metrics using explicit Time Spent values rather than the midpoint Time Spent values.|
|Attribution: All Time Spent values are attributed on the day that the visit ends, even if some of the page views were on a previous day.||Attribution: All Time Spent values are attributed to the day on which each page view occurred.|
Because of these changes in calculation, Adobe Analytics/SiteCatalyst 15 Time Spent metrics can vary significantly from previous versions of SiteCatalyst. Sites with a video implementation should see an increase.
Without non-page events like video views or exit links, time spent on the last page cannot be known.
