What counts as an Analytics impression?

An Analytics billing impression is defined in the same way as a “Play” in the Analytics dashboard. We count an impression when a viewer saw at least one frame of a video. In technical terms, we can count an impression once a session had a Video Startup Time:

Example A

As pictured in the impression log below, the session had a video startup time of 0.39 seconds and consequently will be counted as an Analytics impression.

Example B

As pictured in the impression log below, the session had an error before playback could commence. Consequently, the session also does not display a video startup time and consequently will NOT be counted as an Analytics impression.
