If a publication is registered with an independent auditor e.g. Nielsen, Rajar, ABC, SimilarWeb, etc. we will obtain periodic reports of these figures from the auditor.
If not registered with an independent auditor, online or broadcast in North America, we look to the services of SRDS/Comscore who provide reports of audience figures.
If neither of the above, we seek the figures directly from the publication as a Publisher’s Statement. Please note some media organisations may have a policy of not disclosing figures either for competitive reasons or in cases where they do not carry advertising.
