WHAT IS SPAM SCORE
What is Moz Spam Score?
Moz Spam Score represents the percentage of sites with similar features to yours that have been penalized or banned by Google. It is based on 27 spam signals identified by Moz's machine-learning model from millions of penalized domains. Spam Score ranges from 1% to 100%. Importantly, Spam Score measures your own website's features and content — it is NOT a measure of how spammy the backlinks pointing to your site are, and it does not depend on your backlink profile.
Low Risk
Most legitimate websites fall in this range. A low spam score means the site shares few features with penalized domains. Little to no action needed.
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.
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 measures how many features your site shares with penalized sites. Check all three for a complete picture of your site's SEO health.

WHY CHECK
Why Check Your Spam Score?
Checking Spam Score helps you assess penalty risk and the overall quality of your website. Our free spam score checker gives you Moz Spam Score data instantly so you can spot risky sites before they hurt your SEO.
Assess Penalty Risk
A high spam score suggests your site shares features with penalized domains. Use the spam score checker to catch these signals early and investigate before Google does.
Evaluate Link Partners

Spam Score complements Domain Rating and Domain Authority. DR measures backlink strength, DA measures ranking potential, and Spam Score measures your own site's penalty risk — check all three together.
Avoid Common Mistakes
Many people think disavowing bad backlinks lowers Spam Score — it does not, because Spam Score is based on your site's own features, not your backlink profile. The spam score checker helps you understand what really moves the score.
