# Blended Frequency: Average Ad Views per User

> Measure how many times each user saw your ads across Meta, Google, and TikTok combined. Calculate frequency to optimize reach and avoid ad fatigue.

<Tip>
  The average number of times each unique user saw your ads across all channels.
</Tip>

## Formula

<Info>
  **Blended Frequency** = **Blended Impressions** ÷ **Blended Reach**
</Info>

### Formula Components

| Metric                                                                                                 | Definition                                        |
| ------------------------------------------------------------------------------------------------------ | ------------------------------------------------- |
| [**Blended Impressions**](/reference/metrics/advertising/blended/blended-audience/blended-impressions) | Total ad views across all channels                |
| [**Blended Reach**](/reference/metrics/advertising/blended/blended-audience/blended-reach)             | Unique users who saw your ads across all channels |

| Metadata        |                                                                                                     |
| --------------- | --------------------------------------------------------------------------------------------------- |
| **Type**        | Number                                                                                              |
| **Data Source** | [Meta Ads](/sources/facebook-ads), [Google Ads](/sources/google-ads), [TikTok Ads](/sources/tiktok) |
| **Aggregation** | Ratio                                                                                               |

## Example

Your cross-channel campaigns delivered **8.4M impressions** to **1.2M unique users**:

| Metric                | Value     |
| --------------------- | --------- |
| Blended Impressions   | 8,400,000 |
| Blended Reach         | 1,200,000 |
| **Blended Frequency** | **7.0**   |

On average, each person saw your ads 7 times across Meta, Google, and TikTok.

***

## How It Works

Blended Frequency aggregates impressions and reach from all connected ad platforms, then divides total impressions by unique reach. A frequency of 7.0 means users saw your ads 7 times on average across all channels combined.

## When to Use

| Scenario                           | Action                                                       |
| ---------------------------------- | ------------------------------------------------------------ |
| Detecting ad fatigue               | Frequency above 10–15 often signals diminishing returns      |
| Balancing reach vs. repetition     | Lower frequency = broader reach; higher = deeper engagement  |
| Optimizing multi-channel campaigns | Compare blended frequency to platform-specific metrics       |
| Budget reallocation                | Shift spend to lower-frequency channels if saturation occurs |
