## Example

Your campaigns delivered **3,200,000 impressions** and **28,800 link clicks** across all channels last month:

| Metric               | Value     |
| -------------------- | --------- |
| Blended Impressions  | 3,200,000 |
| Blended Link Clicks  | 28,800    |
| **Blended Link CTR** | **0.90%** |

***

## How It Works

Blended Link CTR aggregates link clicks and impressions from Meta, Google, and TikTok, then calculates the overall link click-through rate. Unlike standard CTR which includes all clicks, Link CTR focuses specifically on clicks that direct users to a destination URL.
