What is the term for the metric that measures the percentage of viewers who watched at least 30 seconds of a video ad?

The metric that measures the percentage of viewers who watched at least 30 seconds of a video ad is known as the "30-Second View Rate." This metric is important in advertising because it provides insight into viewer engagement and the effectiveness of a video ad. Advertisers use this metric to evaluate how well their content captures and retains the audience's attention. A high 30-second view rate often indicates that the ad is compelling enough to hold the interest of viewers for a significant portion of its length, potentially leading to higher brand recall and conversion rates. In digital marketing, understanding viewer behavior through metrics like the 30-Second View Rate is critical for optimizing ad strategies and improving overall engagement.
