## How It Works

TikTok tracks when viewers reach the 25% mark of your video. This represents the first stage of the completion funnel and measures initial content retention. For a 60-second video, 25% completion means 15 seconds watched. High 25% rates indicate your opening hook is effective.

## When to Use

| Scenario            | Action                                                     |
| ------------------- | ---------------------------------------------------------- |
| Hook effectiveness  | High 25% rates mean your opening seconds capture attention |
| Funnel diagnostics  | Compare 25% → 50% → 75% → 100% to find drop-off points     |
| Content pacing      | Low 25% rates suggest the intro needs improvement          |
| A/B testing openers | Test different hooks and compare 25% completion rates      |
