| Measuring content quality                   | Higher 50% views indicate compelling video content            |
| Identifying drop-off points                 | Compare 25%, 50%, 75%, 100% views to find where viewers leave |
| Optimizing video length                     | Low 50% completion suggests videos may be too long            |
