# Sessions Table

The Sessions Table captures data on each visitor's session, including session duration. A session concludes when there has been no activity by the user for 30 minutes. See table structure below.

{% hint style="info" %}
\*For users who want to parse results by match type—similar to how they’re displayed in the front-end application—use the `File Type` column values as your delimiters.
{% endhint %}
