The three tiers Karbon grades against — and where each comes from
| Tier | Value | What it means | Basis |
|---|---|---|---|
| Minimum | 500 | The floor. Below this, something is broken. | Karbon target |
| Recommended | 5.0K | The tier a healthy campaign should hit. | Karbon target |
| Excellent | 50.0K | Top-tier performance worth defending. | Karbon target |
Higher is better for this metric.
Why Retargeting Pool Size matters
Retargeting is the highest-ROI audience. Below 500, platforms cannot optimize delivery. Above 5,000, you have a meaningful pool for segmented retargeting strategies.
