Abstract: Systems and methods are disclosed which facilitate management and monitoring of page-level usage data. Specifically, a client computing device may retrieve content from a remote system for local display. A local interaction monitoring component may monitor local interaction with the content, and transmit local interaction information to the remote system. In one embodiment, interaction may be monitored with regard to predefined portions of the content. In another embodiment, interaction may be transmitted to the remote server for processing, in order to generate page-level usage data. In still more embodiments, page level-usage data may be processed or formatted in order to facilitate ease of retrieval and display. In yet more embodiments, the remote system may enable clients, such as administrators, to view aggregate page-level usage data why viewing a corresponding content.
