Managing page-level usage data

A computing system comprising:

• a physical storage device storing rendering instructions for a content item obtained from a content provider system, wherein the rendering instructions include instructions executable by a processor to conduct monitoring of interactions with the content item that modify which content portions, of which content portions, of a plurality of content portions designating areas of the content item of a predefined height or width, and wherein the monitoring disregards interactions with the content item that do not cause a change in which content portions of the plurality of content portions are displayed on the client computing device;
• a display device to output at least one of the plurality of content portions of the content item;
• and
• a processor configured to execute the instructions to conduct the monitoring, wherein executing the instructions causes the processor to:
• detect a set of local interaction events on the client computing device to modify which content portions of the plurality of content portions are displayed on the display device;
• generate, based at least in part on the set of local interaction events, local interaction information indicating which content portions of the plurality of content portions have been displayed on the display device and further indicating a timing at which content portions of the plurality of content portions are displayed on the display device;
• and
• transmit the local interaction information to a remote monitoring system.

Non-transitory computer readable media comprising rendering instructions for a content item displayable on a display of a computing system, wherein the rendering instructions include instructions executable by a processor of the computing system to conduct monitoring of interactions with the content item that modify which content portions, of a plurality of content portions designating areas of the first content item of a predefined height or width, are displayed on the computing system, and wherein the monitoring disregards interactions with the content item that do not cause a change in which content portions of the plurality of content portions are displayed on the client computing device, wherein the execution of the instructions causes the processor to:

• detect a set of local interaction events on the computing system to modify which content portions of the plurality of content portions are displayed on the display;
• generate, based at least in part on the set of local interaction events, local interaction information indicating which content portions of the plurality of content portions have been displayed on the display and further indicating a timing at which content portions of the plurality of content portions are displayed on the display;
• and
• transmit the local interaction information to a remote monitoring system.
