| **TikTok-Attributed App Install Events** | App download events tracked by TikTok via mobile measurement partners (MMPs) or TikTok SDK within the attribution window |

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

## Example

**Your fitness app campaign drove 2,847 installs in March** across three ad groups targeting different audiences.

| Ad Group             | App Installs | Spend   | Cost per Install |
| -------------------- | ------------ | ------- | ---------------- |
| Health Enthusiasts   | 1,245        | \$2,490 | \$2.00           |
| New Year Resolutions | 982          | \$2,455 | \$2.50           |
| Athletes             | 620          | \$1,860 | \$3.00           |

## How It Works

TikTok tracks app installs using mobile measurement partners (MMPs) and TikTok's own SDK. When a user clicks your ad and installs your app within the attribution window, TikTok counts it as an attributed install.
