## How These Metrics Relate

These metrics form a hierarchy of audience measurement:

* **Google Impressions** counts total ad views across all users
* **Google CPM** = Google Spend ÷ Google Impressions × 1,000 (cost to reach 1,000 people)
* **Google Frequency** = Google Impressions ÷ Reach (how often each person sees your ad)

## Choosing the Right Metric

* **Brand awareness campaigns**: Use Impressions and CPM to maximize reach within budget
* **Ad fatigue monitoring**: Track Frequency to avoid overexposing your audience (typically keep below 3-5x)
* **Efficiency benchmarking**: Compare CPM across campaigns to find cost-effective audience targeting
