## How These Metrics Relate

These metrics form a hierarchy of audience measurement:

* **Page Views** counts every page load (one session can have many page views)
* **Unique Sessions** counts browsing sessions (one visitor can have many sessions)
* **Unique Visitors** counts distinct people using identity resolution
* **New Visitors** is a subset: first-time visitors only
* **New Visitors Percentage** = New Visitors ÷ Unique Visitors × 100
* **Bounce Rate** = Bounced Sessions ÷ Unique Sessions × 100 (measures engagement quality)

Cost and value metrics help you understand efficiency:

* **Cost per Page View** = Ad Spend ÷ Page Views
* **Cost per Session** = Ad Spend ÷ Sessions
* **Page Views Value** = Attributed value from awareness-stage events

## Choosing the Right Metric

* **Traffic volume**: Use Page Views for raw traffic, Unique Sessions for visit count
* **Audience size**: Use Unique Visitors to count distinct people
* **Acquisition analysis**: Use New Visitors and New Visitors % to measure growth
* **Efficiency**: Compare Cost per Page View or Cost per Session across channels
* **Attribution value**: Use Page Views Value to see top-funnel impact on revenue
* **Engagement quality**: Use Bounce Rate to identify landing pages losing visitors
