Abstract: Network address date groups are defined that are associated with a group of electronic objects. Where network address date groups appear to relate to the same person or group, they are assigned an entity group identifier that allows tracking the electronic objects across network address changes. The entity group identifier may then be used by an advertiser or other service provider.

Abstract: The system and method for providing a calculating the incremental value of an online advertising campaign. The incrementality is generated measuring the viewability for every impression delivered during a digital display advertising campaign, or for a representative sample of impressions and comparing a performance measure (e.g., a conversion rate) between viewable and non-viewable impressions to provide a direct measurement of the incremental effect (i.e. the value) of the viewable impression(s) so as to automatically value the online advertising campaign thereby.
