# Blended Advertising Metrics

> Cross-platform advertising metrics aggregated across Meta, Google, and TikTok. Track total spend, reach, and efficiency without switching between ad platforms.

Blended metrics aggregate advertising data from all connected ad platforms—Meta, Google, and TikTok—into unified performance views. Instead of checking each platform separately, see total spend, combined reach, and overall efficiency in one place.

## Why Use Blended Metrics

* **Unified view**: See total marketing performance without platform-switching
* **Budget analysis**: Track combined spend and efficiency across all channels
* **Cross-platform reach**: Understand total audience exposure
* **Simplified reporting**: Export single metrics instead of platform-by-platform data

## How Blended Metrics Work

Blended metrics aggregate data from each connected ad platform:

1. **Meta Ads** — Campaign, ad set, and ad-level data via Marketing API
2. **Google Ads** — Campaign performance via Google Ads API
3. **TikTok Ads** — Campaign data via TikTok Marketing API

Data is pulled daily and aggregated at the metric level. Platform-specific breakdowns remain available in their respective metric categories.
