Device Targeting With Platform-level Keys
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.
Purpose of Platform-level Variables
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.
Platform-level Keys Defined by User Agent
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.
