| Metric | Value | Calculation |
|---|
| Meta Spend | $2,400 | Total ad spend |
| Meta Engagements | 8,000 | Likes + comments + shares + saves |
| Cost per Engagement | $0.30 | $2,400 ÷ 8,000 |
How It Works
Meta Cost per Engagement divides your total ad spend by the number of social interactions your ads received. This metric helps you understand how efficiently your budget drives meaningful social engagement rather than just impressions or clicks.
