Definition: Trust Flow is a proprietary Majestic metric that scores the estimated quality of links pointing to a URL or domain from 0 to 100. Its calculation is based on the link profile’s proximity to a set of sites considered trustworthy within the tool’s link index.
It is not a Google metric, it is not calculated by Moz and it is not a confirmed ranking factor. It is an external indicator that helps analyze link profiles using Majestic‘s methodology and data.

What Trust Flow is used for
Trust Flow provides a reference for the relative quality of the sites linking to a page. It can be used to explore a domain, compare similar URLs or review potential link sources before making a decision.
In a link audit, the score can reveal patterns among backlinks that deserve further review. A high value does not prove that every link is suitable, and a low value does not automatically demonstrate a penalty or quality problem.
The metric is more useful when considered alongside topical relevance, referring domains, the editorial nature of links and the profile’s evolution. Comparing isolated figures from different sectors, countries or website types can lead to incorrect conclusions.
How to interpret the score
The value should be read within the selected index, date and scope. These are the main criteria for interpreting it:
- Scale: The score ranges from 0 to 100, but it is not a percentage and there is no universal quality threshold.
- Analyzed URL: A page, subdomain and root domain may show different values because they receive different links.
- Selected index: Results depend on the links that Majestic has discovered and processed in the index being consulted.
- Market context: Comparisons are more informative between sites with similar topics, functions, markets and sizes.
- Distribution: It is useful to examine which pages concentrate trust and which internal links connect them to the rest of the site.
- Evolution: A time series may reveal profile changes, although each variation should be checked against links gained or lost.
Majestic also provides Topical Trust Flow, which distributes estimated trust across topical categories. This classification helps check whether the areas associated with the profile are related to the site’s actual activity.
Relationship with other metrics
Trust Flow cannot summarize authority, risk or ranking potential on its own. Its interpretation improves when combined with complementary signals:
- Citation Flow: It estimates influence based on link quantity and propagation without assessing proximity to trusted sources in the same way.
- Referring domains: They show whether links come from a diverse base or are concentrated in a small number of sources.
- Topical relevance: It helps distinguish links related to the content from those with a weak or artificial relationship.
- Organic data: Impressions, clicks, queries and ranking pages show real outcomes that a third-party metric cannot replace.
The relationship between Trust Flow and Citation Flow can act as an exploratory signal, but it should not become an automatic rule. Two legitimate sites may have different ratios because of their history, size and link acquisition patterns.
How to improve the link profile
The objective should not be to manipulate a score, but to build a relevant and sustainable link profile. A link-building strategy can work on these areas:
- Linkable content: Studies, resources, tools, data and guides may earn references when they provide original value.
- Editorial relationships: Collaboration with relevant media, organizations and specialists can generate contextual mentions.
- Relevance: A link should make sense by topic, audience and function, not only because of the source domain’s score.
- Diversity: A varied base of referring domains reduces dependence on a single source or link type.
- Internal links: A coherent architecture distributes context and helps users and crawlers reach important pages.
- Periodic audits: Reviewing new, lost, repeated or suspicious links helps identify changes and risks that require investigation.
- Combined monitoring: Trust Flow trends should be compared with the actual profile, visibility and website objectives.
A higher score may accompany a stronger profile, but it does not guarantee rankings or traffic. Decisions should be based on the verified quality of links and their usefulness to the project.
