## How These Metrics Relate

Engagement metrics capture different levels of user investment:

* **Likes** = lowest friction, quick approval
* **Reactions** = emotional response (loves, wows, etc.)
* **Comments** = active conversation participation
* **Shares** = highest value, extends reach organically
* **Saves** = future reference intent

Total Engagements = Likes + Reactions + Comments + Shares + Saves + Clicks

Engagement Rate = Engagements ÷ Impressions × 100

## Choosing the Right Metric

* **Brand awareness**: Track Engagements and Engagement Rate
* **Viral campaigns**: Focus on Shares
* **Content quality**: Compare Engagement Rate across creatives
* **Community building**: Monitor Comments and Reactions
* **Future intent**: Track Saves for purchase consideration
