A first set of usage data for a first set of resources is determined based on information sent as a result of beacon instructions included with the first set of resources. A second set of usage data for a second set of resources is determined based on information received from monitoring applications. Initial usage measurement data for a third set of resources on the network is determined based on the first set of usage data. The third set includes one or more common resources that are included in the first set of resources and the second set of resources. Adjustment factors are determined based on the second set of usage data and applied to the initial usage measurement data. Reports are generated based on the adjusted usage measurement data.
