WHAT IS SPAM SCORE
What is Moz Spam Score?
Spam Score is an SEO metric developed by Moz that predicts the likelihood that a website has been penalized, banned, or flagged as spam. Spam Score ranges from 0% to 100%, with higher percentages indicating a greater risk that the site is spammy or low-quality. Our free Spam Score checker lets you look up the Moz Spam Score for any website instantly. Moz calculates Spam Score by analyzing a domain against a list of spam-related flags or signals — for example, thin content, a low number of pages, or suspicious linking patterns. A high Spam Score doesn't guarantee a site is spam, but it's a warning sign worth investigating, especially before you accept a backlink from or partner with that domain.
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 is essential for protecting your site's SEO health. A Spam Score checker helps you identify toxic or low-quality domains before they can harm your backlink profile, and lets you monitor your own site for spam signals. Accepting backlinks from high-Spam-Score sites can drag down your own rankings, so screening link prospects with a Spam Score checker is a key part of responsible link building. Our free Spam Score checker makes it fast and easy to check Spam Score for any website without a paid Moz subscription.
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
Before accepting a backlink or partnering with a site, check its spam score. A high spam score on a linking domain can drag down your own SEO health.
Complete Your Health Audit
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.
