Majestic Trust Flow vs. Moz Spam Score: Metric Guide
When evaluating the health of a website's link profile, relying on a single metric is a common mistake. A domain might have a high Domain Authority (DA) but still contain a toxic backlink profile that makes it a risky link partner.
To run a reliable audit, SEO professionals use complementary metrics. Ahrefs DR, Moz Spam Score, and Majestic's Trust Flow and Citation Flow are all valuable. In this article, we will compare the majestic checker metrics with Moz Spam Score to show you how to perform deep domain evaluations.
Topic Overview: Understanding Majestic TF & CF
Majestic is an industry-leading link index tool famous for its link quality indicators:
- Citation Flow (CF): A score predicting how influential a URL is based on the sheer quantity of links pointing to it.
- Trust Flow (TF): A score predicting how trustworthy a page is by tracing its distance from highly trusted, human-curated seed directories.
If a site has a high Citation Flow but a low Trust Flow, it usually indicates that the site has acquired a large number of low-quality, automated backlinks.
Deep Semantic Coverage: Majestic vs. Moz Spam Score
While Majestic uses Trust Flow to flag low-quality links, Moz uses a direct spam score checker to flag domains at risk of Google penalties. The Moz Spam Score analyzes 27 layout and link signals on a scale of 0 to 100%.
Comparing the two:
- A site with Low Majestic TF / High CF typically has low-quality link neighbors.
- A site with a High Moz Spam Score has layout and technical signals that look like penalized sites (e.g., thin content, long domain names, lack of contact details).
Using both metrics together prevents you from acquiring backlinks on risky networks.
Practical Application: Running a Metrics Audit
When performing link building or domain purchases:
1. Check Moz Metrics: Paste the domain into our Domain Authority Checker to view DA and Spam Score.
2. Analyze the TF/CF Ratio: If you have access to a Majestic checker, verify that the TF is at least 50% of the CF score.
3. Inspect the Link Quality: If Spam Score is over 10% or TF is under 15, inspect the referring anchor text closely using our Backlinks Checker.
