The ‘Skip Ad’ Metric
Skip rate is a fundamental key performance indicator (KPI) for video advertising on platforms like YouTube. For any skippable ad format, which typically allows a viewer to skip after five seconds, the skip rate is a direct measure of the ad’s failure to engage. It is calculated with a simple formula: (Number of Skips / Total Number of Ad Impressions) x 100%. A high skip rate is a clear signal to a film marketer that their ad creative is not capturing the audience’s attention in the critical opening moments.
Optimizing for a Low Skip Rate
For a movie trailer being used as a pre-roll ad, the first five seconds are the entire battle. Film marketers employ several strategies to combat a high skip rate and earn the viewer’s attention:
- Front-Loading the Action: Placing the most explosive, intriguing, or visually stunning shot from the film right at the beginning.
- Posing a Question: Starting with on-screen text or a voiceover that creates immediate mystery (e.g., ‘What if you discovered your whole life was a lie?’).
- Direct Address: Using a clip of the film’s biggest star looking directly at the camera.
Skip Rate vs. View-Through Rate (VTR)
Skip rate is the inverse of another important metric, the View-Through Rate (VTR). VTR measures the percentage of viewers who watch an ad either to completion or for a significant duration (e.g., 30 seconds). A high skip rate will always mean a low VTR. Marketers analyze both metrics to get a complete picture of an ad’s performance, using the data to A/B test different edits and continually optimize their campaign for maximum viewer engagement and impact.
