Abstract: An example apparatus includes memory and at least one processor to execute first instructions. The first instructions cause the at least one processor to send second instructions from a first server to a client device. The second instructions cause the client device to send first messages to a second server at intervals based on a presentation of media via the client device. The second instructions cause the client device to send a second message to the second server based on a skip request associated with the presentation of the media via the client device. The first instructions further cause the at least one processor to log impressions corresponding to the first messages and the second message, and to determine a duration impression for the media based on the logged impressions. The duration impression identifies the portions of the media that were presented at the client device.
