Video completion rate The percentage of video advertisements that play to completion. Also known as view through rate and video completion rate. (VCR) is a measurement of the percentage of video impressions that played to completion. Index Exchange (Index) collects data across all our video supply to predict video completion rates.
How does it work?
Using publisher The owner of a website or app where advertisements are served.-provided placement identifiers like the Global Placement Identifier (GPID), Index tracks video completions at the most granular level possible. As we receive completion events, we use that data to predict the VCR for the inventory. The following formula is used to predict the VCR percentage:
VCR percentage = (number of completed views / measured impressions) * 100
For example, if the video ad is watched 200 times to completion, and 500 video impressions were measured, the VCR is 40%.
When available, we send the predicted VCR to DSPs in the imp.metric object of an OpenRTB bid request. In the following example, Index has measured the predicted VCR to be 99%:
