What is Spam Score?
Spam Score is a metric developed by Moz that predicts the likelihood that a website has been penalized or flagged as spam by search engines. It is expressed as a percentage from 0% to 100%.
Moz Spam Score is based on a set of 27 correlation flags — site-level features that Moz found to be strongly correlated with sites that have been penalized or banned by Google. The more flags a site triggers, the higher its Spam Score.
It's important to note that a high Spam Score does not necessarily mean a site is spammy. It means the site shares characteristics with sites that have been penalized. Always investigate the specific flags triggered before making judgments.
Spam Score Ranges
- 1-10%: Low Risk — Safe for link building
- 11-30%: Medium Risk — Evaluate carefully before linking
- 31-60%: High Risk — Likely has spammy characteristics
- 61-100%: Very High Risk — Strongly correlated with penalized sites
