Example
Your three video campaigns show different average watch times based on content length and engagement:
| Campaign | Avg Watch Time | Video Length | Watch Ratio |
|---|
| Product Teaser | 8.2 seconds | 10 seconds | 82% |
| Brand Story | 18.5 seconds | 45 seconds | 41% |
| Tutorial Series | 32.4 seconds | 90 seconds | 36% |
How It Works
Meta tracks how long each viewer watches your video ads and calculates the average across all plays. Higher watch time indicates more engaging video content. This includes partial views—if 100 people play your 30-second video and half leave at 10 seconds while half complete it, your average watch time would be 20 seconds.
When to Use
| Scenario | Action |
|---|
| Optimizing video length | Compare average watch time to total length to find ideal duration |
| Testing hook effectiveness | Low watch time on long videos signals weak opening |
| Comparing creative formats | Higher watch time indicates more engaging content style |
| Pacing content structure | Place key messages before average drop-off point |
| Metric | Relationship |
|---|
| Meta Video Plays | Denominator for average watch time calculation |
| Meta ThruPlay Views | Videos watched to completion or 15+ seconds |
| Meta Video Completions | 100% completion views—highest engagement tier |
