| Meta Ads    | \$5,000     | 71,400      | \$0.07     |
| Google Ads  | \$2,500     | 35,700      | \$0.07     |
| TikTok Ads  | \$1,250     | 17,900      | \$0.07     |
| **Blended** | **\$8,750** | **125,000** | **\$0.07** |

## How It Works

Blended CPC (Link) divides your total ad spend across all channels by the total link clicks received. Link clicks specifically measure clicks that take users to your website, excluding engagement clicks like reactions or video views.
