Sometimes publisher's domain is not available - information about the domain is not shared by the seller. This means that the ads were served, but for security purposes, domains were anonymized by the networks.

For these unknown domains, we're grouping performance metrics under the 'Other' record in the 'Publisher website performance' report.

The same situation can happen for geolocations (on a country or a region level) - user location is not always shared, so we cannot specify a location in our reports.

For these unknown locations, we're grouping performance metrics under the 'Other' record in the 'Geolocations' report.
