# Stats Overview Cards

> Understand your key SKAN metrics at a glance with total installs, CV null counts, and null rates

## Overview

The Stats Overview Cards display four key metrics that provide a snapshot of your SKAN performance. Each card shows data for your selected time period as well as lifetime totals, along with a trend graph to visualize changes over time.

<Note>
  **Important note**: The install date shown is when the postback was received, not when the actual install happened. Apple does not send postbacks immediately after an install. After a user installs and launches an app, Apple delivers attribution postbacks on a delayed schedule (within \~48-72 hours).
</Note>

## Metrics

The widget displays data for the following metrics:

### Installs (SKAN)

Returns the count of valid SKAN postbacks.

**What you'll see:**

* **Filtered Period**: Number of installs within your selected date range
* **Lifetime**: Total installs since you started using Linkrunner
* **Trend Graph**: Daily install volume over the selected period

### Reinstalls (SKAN)

For reinstall events, Apple includes redownload=true in the SKAN postbacks sent to Linkrunner. The Reinstalls metric reflects the number of reinstalls during the selected period, as reported by these postbacks.

**What you'll see:**

* **Filtered Period**: Number of reinstalls within your selected date range
* **Lifetime**: Total reinstalls since you started using Linkrunner
* **Trend Graph**: Daily reinstall volume over the selected period

### Conversion Value Null Count

This metric counts SKAN postbacks with a null conversion value, meaning no post-install actions were reported. This may happen when Apple limits reporting due to privacy tier requirements.

**What you'll see:**

* **Filtered Period**: Number of null conversion values in your selected date range
* **Lifetime**: Total null conversion values since you started using Linkrunner
* **Trend Graph**: Daily null count over the selected period

### Conversion Value Null Rate

The number of postbacks received with a conversion value of null divided by the number of SKAN installs.

**What you'll see:**

* **Filtered Period**: Percentage of null conversion values in your selected date range
* **Lifetime**: Overall null rate since you started using Linkrunner
* **Trend Graph**: Daily null rate percentage over the selected period
