## How These Metrics Relate

Google Spend is the foundation for all efficiency calculations:

* **Google CPC** = Google Spend ÷ Google Clicks
* **Google CPA** = Google Spend ÷ Google Purchases
* **Google ROAS** = Google Purchases Value ÷ Google Spend
* **Google CPM** = Google Spend ÷ Google Impressions × 1,000

## Choosing the Right Metric

* **Budget tracking**: Use Google Spend to monitor daily, weekly, or monthly ad investment
* **Efficiency analysis**: Combine with conversion metrics to calculate ROAS and CPA
* **Cross-channel comparison**: Compare Google Spend against Meta Spend or TikTok Spend for budget allocation decisions
