The three tiers Karbon grades against — and where each comes from
| Tier | Value | What it means | Basis |
|---|---|---|---|
| Minimum | 40.0% | The floor. Below this, something is broken. | Karbon target |
| Recommended | 20.0% | The tier a healthy campaign should hit. | Karbon target |
| Excellent | 5.0% | Top-tier performance worth defending. | Karbon target |
Lower is better for this metric.
Why Audience Overlap matters
High overlap means your ad sets compete against each other in auction, driving up costs. Clean audience separation lets each ad set optimize independently.
Karbon target
No independent public benchmark exists for Audience Overlap as Karbon measures it. The tiers above are Karbon Agency's own grading targets for local-business campaigns, not an industry average, and we don't cite one we haven't found.
