How to read spam scores
Moz groups spam scores into three bands: 0–30 is a low spam score (low risk), 31–60 is medium risk / moderate risk, and 61–100 is high risk. A high spam score means more spam signals on the domain and its inbound links — not proof it was penalized by Google.
Always use spam score next to Domain Authority. A modest number on a strong site is different from the same spam scores on a thin content domain with almost no referring domains. Treat the number as spam risk, not a verdict, and do not confuse a dash with low spam signals.
