Abstract: A computerized system and techniques facilitate the monitoring and management of online behaviorally-targeted advertising. In certain embodiments, electronic notifications related to advertising practices of members of an online advertising ecosystem are presented to users based on the discovery of elements of online content aimed at delivering targeted advertising messages to viewers of the content.

Abstract: A system for accurately estimating global impression volumes at tag and host levels, and for computing global page views and reach estimates, collects impression volumes for various tracking technologies and for several hosts from a panel of users. The collected panel data is normalized, e.g., to minimize spurious and/or non-human activity data. A scaling factor is computed using measured global impression volume of a reference tag and impression volume of the reference tag with respect to the panel. The required global estimates are obtained by scaling the normalized panel data using the computed scaling factor.
