Systems and methods for determining delivery hierarchical information for an Ad unit. In an example method performed at a server, location information is received from a user computer system via a network. The location information is associated with an Ad unit presented on a webpage accessed by the user computer system. The server determines if any previously stored signature information matches with at least a portion of the received location information, then extracts domain information for any portions of the received location information that matches with any previously stored signature information. Then, at least partial delivery hierarchical information is generated based on the extracted domain information. The process repeats for other location information associated with the Ad unit that is received at the server. The generated delivery hierarchical information is aggregated. Then a report is generated based on the aggregated delivery hierarchical information.
