Abstract
A page of content includes instructions that, when executed by a client device presenting the page, obtain a visibility state of the page describing presentation of the page of content to a user and a time when the visibility state was obtained. Execution of the instructions also generates an identifier with which the visibility state and the time are associated. The instructions also obtained updated visibility states, obtains times when the updated visibility states are obtained, and associates the updated visibility states and their corresponding times with the identifier. The client device communicates the obtained visibility state, updated visibility states, and corresponding times to an online system in association with the identifier. Based on the times corresponding to the visibility state and the updated visibility states, the online system determines a duration the page was presented.
