| --------------- | --------------------------------------------------------------------------------------------------- |
| **Type**        | Number                                                                                              |

## Example

Your video campaigns generated **24,500** 15-second views this week:

| Platform   | 15s Views | Share |
| ---------- | --------- | ----- |
| Meta Ads   | 14,200    | 58%   |
| Google Ads | 6,850     | 28%   |
| TikTok Ads | 3,450     | 14%   |

## How It Works

This metric counts video views where the viewer watched at least 15 seconds. It aggregates equivalent metrics from each ad platform into a single cross-channel view. This threshold indicates meaningful engagement beyond initial impressions.
