1–30%
Low Risk
Moz's low band. It is still a model output, not proof that every page or link on the domain is safe or relevant.

WHAT IS SPAM SCORE
What is Moz Spam Score?
Moz Website Spam Score is the percentage of sites with features similar to the researched domain that Moz found penalized or banned in its training data. It is a correlation-based third-party metric, not the probability that Google will penalize this domain. It also has nothing to do with whether an email will reach an inbox. Use the result to start a review, not to automate a verdict.
31–60%
Medium Risk
Worth a closer look. The site shares some features with penalized domains. Use the spam score checker as a prompt to investigate quality and content further.
61–100%
High Risk
The site shares many features with penalized domains. This is a strong signal to investigate — though a high spam score is not by itself proof that a site is spam.
Spam Score, DR & DA — How They Fit Together
The three metrics measure different things and complement each other. Domain Rating (DR) measures backlink strength. Domain Authority (DA) predicts ranking potential. Spam Score reports Moz's correlation-based website signal. Compare the metrics only with their different providers and limitations in mind.
HOW TO USE
How to Check Spam Score of a Website
Enter one public domain to request its Moz Spam Score. The result shows the percentage and Moz band when available; this checker does not return the domain's individual contributing features. Investigate the site's content, relevance, and link context before making a decision.
01
Enter a Domain
Type any domain name into the spam score checker search box above — for example, moz.com. Our free spam score checker will look up the Moz Spam Score for that website.
02
View Your Spam Score
The checker displays the returned Moz percentage and its Low, Medium, or High investigation band. If the provider has no score, the result remains unavailable rather than becoming zero.
03
Investigate the Signals
A high Spam Score is not a verdict. Treat the returned percentage as a prompt to inspect the site's content, link profile, relevance, ownership, and actual search visibility; this checker does not expose the domain's individual model features.
WHY CHECK
Why Check Your Spam Score?
Spam Score can help prioritize which domains deserve closer review. It cannot establish that a domain is toxic, that one backlink is harmful, or that Google has taken action. Combine it with topical relevance, content quality, real visibility, and the context of the specific linking page.
Prioritize Investigation
A higher score means the domain shares more characteristics with sites in Moz's penalized or banned training set. It tells you where to investigate, not what Google will do.
Evaluate Link Partners
For a link or partnership review, use Spam Score alongside the site's topic, content, audience, and the exact page involved. Never reject a site from this number alone.
Complete Your Health Audit
Spam Score, DR, and DA are separate vendor metrics. Comparing them can reveal questions to investigate, but none is a Google ranking factor or complete site-health diagnosis.
Avoid Common Mistakes
Do not disavow a link solely because a domain has a high Spam Score. Investigate the site's relevance and actual link context, and use Google's disavow tool only for the specific unnatural-link situations Google describes.
