Google has updated the functionality of Google Chrome and all Chromium-based browsers to minimize the information collected via the User-Agent
header.
Starting with March 2023, Audience Manager supports these updates by leveraging Experience Platform Web SDK. To continue using trait information provided via the User-Agent
header, you must use Web SDK and enable High Entropy User-Agent Client Hints.
These updates are not supported by DIL, so Audience Manager customers who use DIL will not be able to collect trait information via the User-Agent
header.
Describes the common platform-level key-value pairs you can use to target users with device-related variables across all properties in your Audience Manager account.
Platform-level variables let you take data passed in from a particular site and make it available for targeting across all the properties in your Audience Manager account. These variables are formed by key-value pairs with the key prefixed by d_
as shown below.
The Data Collection Servers extract the values for these keys from the user agent header in HTTP
requests. The values represent device-level information from the Device Atlas database. The signals in the table below are available, as extracted from the user agent example. Download a list of the most common keys, according to Device Atlas measurements.

Even if one or more signals cannot be retrieved from the user agent header, the other signals will still be passed to the Data Collection Servers.
