<Info>

</Info>

### Formula Components

| Metric                | Definition                                                                                        |
| --------------------- | ------------------------------------------------------------------------------------------------- |
| **Video Completions** | Individual instances where a viewer watched your entire video ad from the first frame to the last |

| Metadata        |                                   |
| --------------- | --------------------------------- |
| **Type**        | Number                            |
| **Data Source** | [Meta Ads](/sources/facebook-ads) |
| **Aggregation** | Sum                               |

## Example

Your brand story campaign generated **4,250 video completions** across three video lengths:

| Video                | Length | Completions | Completion Rate |
| -------------------- | ------ | ----------- | --------------- |
| Customer Testimonial | 28 sec | 2,100       | 18.2%           |
| Product Tutorial     | 45 sec | 1,450       | 12.8%           |
| Brand Documentary    | 90 sec | 700         | 6.1%            |

Shorter videos typically see higher completion rates, but completions on longer content signal deeper engagement.

## How It Works

Meta registers a video completion when someone watches your entire video ad from start to finish. This is the strictest engagement metric—viewers who reach 100% have seen your complete message. Completions are especially valuable for videos with calls-to-action or key information at the end.

| ------------------------------ | -------------------------------------------------------- |
| Evaluating message delivery    | High completions mean viewers saw your full story        |
