# Time spent per visitor (seconds)

The 'Time spent per visitor (seconds)' metric shows the average amount of time that visitors interact with a given dimension value during a visitor's entire lifetime.

This metric is not available in Data Warehouse due to its different processing architecture.

## How this metric is calculated

## Percentages above 100%

This metric frequently contains percentages above 100%. The denominator is the entire dimension's time spent per visitor, and the numerator is the dimension value's time spent per visitor. If the entire dimension's time spent per visitor is lower than a given dimension value's time spent per visitor, you'll see percentages above 100%. Sorting ranked reports by this metric shows anomaly time spent per visitor values, which is typically not valuable. Adobe recommends sorting by another metric, such as
Visits
, in ranked reports.
