Abstract: This patent document describes a method and system which enables website operators to classify the behaviors of website visitors using a measurement script, without the use of third party cookies. The method includes providing multiple user-behavior-classification rule sets, each rule set including user actions for a corresponding behavior class, and including the rule sets in a measurement script. The script is configured to cause each user electronic device on which it is installed to, in response to detecting device interaction that correspond with at least one predefined user action of a behavior class, store, in a first party cookie, identifiers corresponding to the behavior classes. The method further includes making the script available to multiple web servers, each of which serves a unique website including one or more pages that provide access to the script, wherein the network server is not provided access to the first party cookies.

Abstract: When a server serves web pages and/or software application pages with digital ads to client devices, a system determines viewability scores for individual ad insertion spaces on the pages. The system determines viewability scores for each field based on the time at which at least a threshold percentage or ratio of the field's pixels where viewable and not off-screen or obscured by another open window. The system or the server may then select digital ads to serve to each field based on the field's viewability score.
