There are some common terms that you will need to understand when using the Digital Analytics Program (DAP).

  • Total pageviews
  • Total sessions
  • Bounce rate
  • Total users
  • Average session duration

A dimension is a data attribute or characteristic that provides additional information about your website or app user. Standard dimensions include:

  • Device
  • Platform
  • Traffic source
  • Country
  • City
  • Page path

Sessions and views

A session (or visit) is a period of time during which a user interacts with your website or app. Total sessions is a count of the total number of sessions (visits) to your website and/or mobile app. Sessions tell you how much time users spend on your site. A session begins when a user opens a website and/or app and ends when they close the website and/or app or are inactive for 30 minutes.

A view (or pageview) is the total number of web pages and/or app screens that users saw. A screenview is the app equivalent of a pageview. A user can view multiple pages or screens during a single session. Views show you the relative popularity of different pages.

Properties and subproperties

A property refers to the account used for Google Analytics, DAP uses Google Analytics 360 to collect and analyze web traffic data.

A subproperty is a way to group data and measurements by parent agency, allowing agencies to find data for their websites more quickly. Agency-specific subproperties are set up at the parent agency level (e.g., Department of Health and Human Services, Department of Defense, General Services Administration).

To use agency-specific data, choose the corresponding agency subproperty. Data for lower-level divisions within an agency (e.g., bureaus, departments, offices, sub-agencies, etc.) are reported inside the main agency subproperty.

To view governmentwide data for all websites using DAP, visit and sign in with your official .gov or .mil email address. Then, choose the option, 0 - DAP Gov-wide View.


You must use the Agency and Sub-agency parameters when implementing the DAP code script. Visit the Get started with DAP page in this guide for more information.
