A client-side user action analysis engine (“analysis engine”) identifies user interactions with a client-side utility and provides data representing the interactions to a server side online resource analytics system (“analytics system”). The analysis engine represents user interactions with the client-side utility as network addresses for presentations of online resources to a user in a browser. The analysis engine provides the network addresses to the analytics system and statistics for the user interactions with the client-side utility are computed based on the network addresses. Reporting data specifying the statistics are received from the analytics system for presentation on a display device. The statistics provide information about user interactions with features of the client-side utility.
