Adobe collects data on your site by receiving an image request generated by the visitor. The
trackingServer variable determines the location an image request is sent. If this variable is not defined correctly, your implementation can experience data loss.
Changing this value makes AppMeasurement look for cookies in a different location. Unique visitor count can temporarily spike in reporting as visitor cookies are set in the new location.
Tracking Server is a field under the General accordion when configuring the Adobe Analytics extension.
If this field is left blank, it defaults to
s.trackingServer variable is a string that contains the location to send data.
Some implementations point data to
2o7.net. While this is a valid data collection domain, it does not use regional data collection. Implementations using
2o7.net see slightly higher image request response times.
The value for this variable depends on if you use first-party cookies or third-party cookies. Adobe strongly recommends using first-party cookies in your implementation.
If you use a first-party cookie implementation, it is likely that someone in your organization has already completed the first-party cookie process. See First-party cookies in the Experience Cloud in the Core Services user guide for more information on the first-party cookie process.
The individual who initially configures the first-party cookie implementation also defines the domain and subdomain used. For example:
s.trackingServer = "data.example.com";
Increasing privacy practices in modern browsers make third-party cookies less reliable. Adobe recommends following the first-party cookie workflow.
If you use a third-party cookie implementation, the value for
trackingServer is a subdomain of
data.adobedc.net. For example:
s.trackingServer = "example.data.adobedc.net";
Pick a subdomain unique to your organization, unlikely to be picked by another organization that uses Adobe Analytics. The visitor namespace assigned to your organization is recommended. Make sure that all implementations in your organization use the same tracking server. It can be helpful to maintain this information in a solution design document.
Your organization may already be using a 3rd party tracking server in the
2o7.net domains. These were primarily used in previous versions of Adobe Analytics and are still valid.
Do not use any subdomains deeper than
example.data.adobedc.net. For example,
custom.example.data.adobedc.net is not a valid tracking server.
