Understanding Moz Spam Score: Protecting Your Site From Algorithmic Penalties

Google's SpamBrain and manual action teams penalize domains with artificial link velocity, thin content syndication, and footprint manipulation. Moz Spam Score provides an early warning radar by correlating your target domains against 27 known characteristics of penalized websites.

1-30%

Low Risk Tier

Standard healthy domains. Natural backlink distributions, balanced anchor text, and clean historical registration footprints. Safe for link building.

31-60%

Medium Risk Tier

Caution advised. May contain repetitive C-class IP links, excessive external outlinks, or automated guest post networks. Perform manual review.

61-100%

High Risk Tier

Severe toxic footprint. Multiple spam flags triggered, thin spun text, or direct algorithmic penalties. Recommend disavowing immediately.

Frequently Asked Questions

Everything you need to know about metrics calculation, credits, and accuracy.

What is Moz's Spam Score and how is it calculated?▼

Moz's Spam Score represents the percentage of sites with similar backlink and on-page features that were found to be penalized or banned by Google. It operates on 27 distinct correlation flags identified through massive link graph machine learning.

What Spam Score is considered dangerous for SEO?▼

Scores between 1% and 30% are considered Low Risk. Scores between 31% and 60% are Medium Risk. Scores of 61% to 100% represent High Risk, and acquiring links from or building on these domains is strongly discouraged.

Does having a 1% to 5% Spam Score hurt my website?▼

No. A low Spam Score between 1% and 10% is completely normal across the web. Even high-authority publications like Forbes and The New York Times have small non-zero Spam Scores due to natural web scraper links.

Can I export toxic domains directly to a Google Disavow file?▼

Yes! You can filter results to domains exceeding 30% or 60% Spam Score and export them directly formatted for Google Search Console disavow uploads.
