Overview

This article explains how Siteimprove defines and classifies devices in Analytics, including how different technologies (user agent and viewport size) determine device categories.

Definition

Siteimprove classifies devices based on the user agent (browser in most cases) used by the visitor.

Note that the category "Desktop" includes other devices such as gaming consoles and smart TV.

How devices are classified

Siteimprove uses two primary methods to define devices:

User agent (browser-based classification)
Viewport width (Behavior Map classification)

You can view the different browsers used on your site by going to Analytics > Visitors > Browsers.

Device categories + thresholds

In Behavior Map, devices are defined by browser window (view port) width*:

Desktop: 1067–1366px wide (and above)
Tablet: 544–1066px wide
Mobile: 0–543px wide

Note: View port widths have been standardized in the Siteimprove Intelligence Platform based on more common device screen sizes.
