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

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 (at the country or 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.
