What's a good Cross-Domain Accuracy?
Karbon Agency's target for Cross-Domain Accuracy is 85.0% or higher. That is Karbon's own grading target, not a published industry average. Accuracy of user tracking across multiple domains in the funnel. Excellent is 95.0% or higher (Karbon target), and the minimum acceptable tier is 70.0% or higher (Karbon target).

The three tiers Karbon grades against — and where each comes from
| Tier | Value | What it means | Basis |
|---|---|---|---|
| Minimum | 70.0% | The floor. Below this, something is broken. | Karbon target |
| Recommended | 85.0% | The tier a healthy campaign should hit. | Karbon target |
| Excellent | 95.0% | Top-tier performance worth defending. | Karbon target |
Higher is better for this metric.
Why Cross-Domain Accuracy matters
When users move between domains (e.g., landing page to booking system), broken cross-domain tracking creates data gaps and inflated user counts.
