Trust Flow (TF) is an SEO metric created by Majestic that scores how trustworthy a URL or domain appears based on the quality of backlinks pointing to it. It runs on a 0-100 scale, where higher scores indicate more links from strong, authoritative websites.
In short: Trust Flow is a backlink quality score.
How Does Trust Flow Work?
Majestic does not just count links. It starts from a set of trusted “seed” sites — well-known, authoritative domains — and measures how close your site is to them through the backlink graph.
Key principles:
- Links from trusted, high-TF sites pass more Trust Flow to your site
- Links from weak or spammy sites pass little or no Trust Flow
- The scale is logarithmic — going from TF 10 to 20 is easier than going from 40 to 50
Trust Flow can be measured per URL (specific pages) or per domain/subdomain (overall authority).
Trust Flow vs Citation Flow
Majestic uses two complementary backlink metrics:
- Trust Flow (TF): Measures the quality and trustworthiness of your backlinks. Answers: “How trustworthy are the sites linking to you?”
- Citation Flow (CF): Measures the quantity and raw link power. Answers: “How many links and how much link equity do you have?”
Common patterns when comparing TF and CF:
- High CF, low TF: Many links, but a significant portion are low-quality or spammy
- Low CF, higher TF: Fewer links, but from strong, trusted sources
- Balanced TF and CF: Generally indicates a healthy backlink profile
Most SEOs look at both metrics together and use the TF/CF ratio as a quick quality indicator.
Is Trust Flow a Google Ranking Factor?
No. Trust Flow is not a Google metric. It is a third-party score from Majestic used as a proxy to estimate link trustworthiness — similar to how Domain Rating (Ahrefs) or Domain Authority (Moz) function.
That said, TF is useful because backlink quality genuinely matters for search rankings. Trust Flow gives you an indirect way to measure something Google does evaluate, even if Google uses different internal methods.
Why Trust Flow Matters for SEO
- Link prospect evaluation: Quickly assess whether a potential backlink source is trustworthy before investing outreach effort
- Backlink profile auditing: Identify low-trust links that may be dragging down your profile quality
- Competitor benchmarking: Compare the trust quality of your backlink profile against competitors in your niche
- Spam detection: Sites with very low Trust Flow relative to their link volume are likely spammy or manipulative
How to Improve Trust Flow
- Earn links from high-authority sites: Focus outreach on reputable publications, industry organizations, and established brands in your space
- Disavow toxic backlinks: Remove or disavow links from spammy, low-quality sites that dilute your trust signals
- Create valuable content: Original research, data studies, and comprehensive guides naturally attract links from trusted sources
- Build real relationships: Digital PR and genuine industry connections lead to higher-quality link placements than mass outreach
