Trust Flow (TF) is a proprietary link quality metric from Majestic SEO, scored 0-100. It measures how close a URL or domain is to a set of manually verified trusted seed sites — major authoritative websites Majestic has confirmed as genuinely trustworthy. The closer your backlink profile is to these seed sites, the higher your Trust Flow score and the higher the perceived quality of your link profile.
Trust Flow is one of the most widely used third-party link quality indicators in SEO. Understanding what it measures, how it differs from Citation Flow, and how to use it in your link building analysis will help you make better decisions about which links to pursue and which sites to avoid when evaluating link opportunities.
What is Trust Flow?
Trust Flow is a metric developed by Majestic SEO — one of the largest backlink databases in the world. Majestic describes Trust Flow as a measure of the "quality" of links, calibrated against a set of seed sites that Majestic has manually selected as authoritative sources of truth on the web.
The concept works like PageRank in principle: trust flows through the web via links. If a government website links to a news site, some trust flows from the government domain to the news site. If that news site then links to your blog, some of that trust flows on to you. The further you are (in click distance) from the original seed sites, the lower your Trust Flow score.
Key attributes of Trust Flow:
- Scale: 0 to 100, logarithmic (like Domain Authority). Moving from 20 to 30 is far easier than moving from 60 to 70.
- Scope: Exists at both the URL level and the root domain level. You can check a single page's TF or an entire domain's TF.
- Topical: Majestic also offers Topical Trust Flow, which shows what topics a site's links are associated with, giving context about a domain's niche relevance.
- Pairing: Always evaluated alongside Citation Flow (CF), which measures link quantity. The TF/CF ratio determines the health of a link profile.
Trust Flow is a Majestic-proprietary score. Google does not use it. However, because it measures something real — link quality and proximity to authoritative sources — it correlates reasonably well with Google's own assessment of link quality. It is a useful proxy, not a direct ranking signal.
Trust Flow vs Citation Flow
Majestic's two primary metrics are designed to be used together. Understanding both is essential for meaningful link analysis:
| Metric | What it measures | What high score means | What low score with high other means |
|---|---|---|---|
| Trust Flow (TF) | Link quality — proximity to trusted seed sites | Many high-quality, authoritative links | Low TF + high CF = mostly low-quality links |
| Citation Flow (CF) | Link volume — number of links pointing to URL | Many links from any source, good or bad | Low CF + high TF = few but excellent links |
The TF/CF ratio (also called the Ratio) is the most informative combined signal:
- TF/CF ratio above 0.5: Healthy. More quality links than junk. A normal, well-maintained link profile.
- TF/CF ratio around 1.0: Excellent. Trust and citation are balanced. Strong editorial links dominating the profile.
- TF/CF ratio below 0.3: Concerning. High volume of low-quality or spammy links with little trust. Common in sites hit by negative SEO or those that bought links.
Trust Flow score benchmarks
What constitutes a good Trust Flow score depends heavily on your niche and the age of your domain. Here are rough benchmarks:
| TF Score | Typical site type | Link building position |
|---|---|---|
| 0-10 | New sites, thin link profiles, heavily penalised sites | Early-stage — focus on quality over quantity |
| 10-25 | Established niche sites with some editorial links | Typical SMB range — room to grow |
| 25-40 | Well-linked niche authority sites, regional news | Strong position — maintain quality incoming links |
| 40-60 | Major industry publications, established brands | Excellent — highly competitive for most niches |
| 60+ | Wikipedia, BBC, NYT, government sites, universities | Exceptional — among the most linked-to sites on the web |
Topical Trust Flow
Majestic's Topical Trust Flow (TTF) extends the basic metric by categorising a site's link profile into over 800 topic categories. This reveals not just whether a site has strong links, but which topics those links are associated with.
Topical Trust Flow is useful in several specific link building scenarios:
- Evaluating prospect relevance. A high TF site in the Health category is more valuable for a health-related link than a high TF site whose links are all in the Technology category.
- Understanding your own niche authority. Your site's top Topical Trust Flow categories show Google's signals about your topical niche — important for E-E-A-T evaluation.
- Competitor analysis. Comparing your TTF categories to competitors' reveals where their link profiles are stronger and which topic verticals you should target for link building.
How to improve Trust Flow
Because Trust Flow measures proximity to trusted seed sites, improving it requires acquiring links from sites that are themselves well-connected to authoritative sources.
- Target high-TF linking domains. When prospecting for link opportunities, filter candidates by Trust Flow using Majestic or a tool that incorporates Majestic data. Prioritise sites with TF above 20 in relevant topical categories.
- Pursue editorial links from established publications. Getting featured in genuine editorial content on major industry publications — not paid placements, not advertorials — earns the highest-quality trust signals.
- Create linkable assets. Original research, data studies, free tools, and comprehensive guides attract natural high-TF links from sites that cite quality sources.
- Digital PR campaigns. Pitching data-backed stories to journalists at major publications earns links from news sites, which typically have very high TF scores.
- Disavow or remove toxic links. Low-TF links drag the average quality of your profile down. Use Google's Disavow Tool to neutralise links from known spam or link farm domains.
- Build local citations carefully. For local SEO, focus citations on established directories (Google Business Profile, Yelp, industry-specific directories) that have high TF themselves.
- Guest posting on quality sites. Contributing expert content to well-established niche publications earns editorially placed links that directly contribute to TF growth.
Purchasing links from private blog networks (PBNs) or link brokers typically involves low-TF sites that inflate Citation Flow without improving Trust Flow. These link profiles (high CF, low TF) are easily identifiable in Majestic and represent a significant risk — Google actively targets unnatural link patterns that match this profile.
Using Trust Flow in link building analysis
Practical applications of Trust Flow in day-to-day SEO and link building work:
- Link prospect qualification. Filter outreach targets by minimum TF threshold (typically TF 15-20+) to ensure you are spending time on worthwhile opportunities.
- Competitor backlink audit. Export competitor backlinks from Majestic, sort by TF descending, and identify the highest-quality links to reverse-engineer with your own outreach or content.
- Link velocity monitoring. Sudden drops in TF can indicate acquired links being deindexed or disavowed by the source domain. Regular monitoring catches these changes before they affect rankings.
- Evaluating inbound link requests. When sites request link exchanges or paid placements, TF provides a quick quality filter. Below TF 10 with high CF is an immediate red flag.
- Domain acquisition due diligence. When evaluating expired domains or domain acquisitions, TF is a critical quality signal. High CF with low TF suggests the domain's history includes manipulative link building.
Common mistakes with Trust Flow
- Treating TF as a ranking factor. Trust Flow is a Majestic metric, not a Google metric. It is a quality proxy, not a direct ranking signal.
- Looking at TF in isolation. Always pair TF with CF and the TF/CF ratio. A site with TF 40 and CF 80 is different from a site with TF 40 and CF 42.
- Ignoring Topical Trust Flow. A high-TF site in the wrong topic category provides less value than a moderate-TF site in your exact niche category.
- Optimising only for TF. Chasing TF score by acquiring links solely based on TF ignores relevance and traffic — a high-TF link from an irrelevant category adds less SEO value than assumed.
- Not monitoring TF over time. Trust Flow can decrease if high-quality linking domains remove their links. Regular monitoring is required to detect link loss early.
Frequently asked questions
Trust Flow (TF) is a Majestic SEO metric that scores the quality of a website's or URL's backlink profile on a scale of 0-100. It measures how close a site is to Majestic's manually verified "trusted seed sites" — major authoritative websites. A higher score means the site receives high-quality links from reputable sources.
Trust Flow is scored 0-100. For most niche websites, a TF of 20-30 is decent; 30-50 is strong; 50+ is excellent, typically seen on major media publications, universities, and established industry sites. The key benchmark is whether your TF/CF ratio is above 0.5.
Citation Flow measures the volume of backlinks to a site — how many links point at it. Trust Flow measures quality — how trustworthy those links are. A site with high CF but low TF has many low-quality links. The TF/CF ratio is the most useful combined signal for evaluating a link profile's health.
Improve Trust Flow by acquiring backlinks from highly authoritative sites: major news publications, government and education sites, established industry directories, and high-TF niche websites. Also disavow toxic low-TF links dragging the score down. Creating citation-worthy content (original research, data, tools) attracts high-quality editorial links naturally.
No. Trust Flow is a Majestic-specific metric. Domain Authority (DA) is a Moz metric. Domain Rating (DR) is an Ahrefs metric. They all attempt to measure link authority but use different methodologies. None are official Google metrics — they are third-party proxies for understanding relative link quality.
