The completion rate is an essential metric that helps advertisers and publishers assess how engaging and relevant their video ad content is to the audience. A high completion rate indicates that the video content resonated well with viewers, encouraging them to watch the ad. In contrast, a low completion rate may suggest that the ad may not capture viewers’ attention or align with their interests.

People often express the completion rate as a percentage, and they calculate it using the following formula:

Completion Rate % = (Number of viewers who completed the video / Total number of viewers) x 100
