The three tiers Karbon grades against — and where each comes from
| Tier | Value | What it means | Basis |
|---|---|---|---|
| Minimum | 3.5 stars | The floor. Below this, something is broken. | Karbon target |
| Recommended | 4.2 stars | The tier a healthy campaign should hit. | Karbon target |
| Excellent | 4.7 stars | Top-tier performance worth defending. | Karbon target |
Higher is better for this metric.
Why Google Review Rating matters
Review rating is the first trust signal potential customers see. Below 4.0 stars, most people will choose a competitor. Above 4.5, you dominate local search results.
