Citation Flow vs Trust Flow comes up whenever someone vets a link prospect or an expired domain. The two numbers sit side by side in Majestic, they share a 0 to 100 scale, and it is tempting to treat the higher one as the verdict. That reading throws away the only useful thing the pair offers, which is the relationship between them.
This piece sets out what each score measures, in Majestic’s own words, and how to use the gap between them as a prompt for inspection rather than a pass or fail.
What Trust Flow measures
Majestic’s glossary defines Trust Flow as “a score based on quality, on a scale between 0-100”. The quality comes from proximity: Majestic starts from a set of trusted seed sites that have been manually reviewed, and a site scores higher the more closely it connects to them through links.
The logic is that trustworthy sites rarely link to junk. A site linked from a seed site, or from sites the seeds link to, inherits some of that trust. A site whose links come only from pages far removed from any seed scores low, however many of those links it has. That is what makes Trust Flow hard to inflate cheaply: you cannot manufacture proximity to a reviewed seed set with volume alone.
What Citation Flow measures in SEO
Citation Flow is the other half. Majestic describes it as “a score between 0-100 which helps to measure the link equity or ‘power’ the website or link carries.” It reflects how much link weight flows to a site, with no judgement about where that weight came from.
On its own, Citation Flow rewards volume. A site with thousands of links from directories, scraped pages and comment sections can post a respectable Citation Flow. That is not a flaw in the metric; it is doing what it says. It just means the number answers “how much?” and never “from whom?”.
Majestic is explicit that the two belong together: “Citation Flow and Trust Flow form the Majestic Flow Metric algorithm.” One is the quantity measure and the other is the quality measure. Read only one and you have half a metric.
| Metric | Majestic’s definition | What it answers |
|---|---|---|
| Trust Flow | “A score based on quality, on a scale between 0-100” | How closely is this site connected to trusted seed sites? |
| Citation Flow | “A score between 0-100 which helps to measure the link equity or ‘power’ the website or link carries” | How much link weight reaches this site? |
| Topical Trust Flow | “A series of numbers, on a log based scale between 0-100” | In which topics does this site have influence? |
Citation Flow vs Trust Flow: reading the gap
Because one measures quality and the other quantity, the useful signal is how far apart they sit. When both are similar, the link profile’s size and its connection to trusted sites roughly match. When Citation Flow is far higher than Trust Flow, the site has plenty of links but few of them lead back towards trusted sources.
You will see “ideal ratios” quoted for this, usually as a single number. Majestic’s glossary does not give one, and we would not treat any fixed ratio as a rule. A wide gap is a reason to open the backlink list and look, nothing more. Sometimes it reveals a pile of spam. Sometimes it reveals a young site with lots of ordinary links that simply has not been cited by anyone prominent yet.
The reverse pattern is rarer and usually less worrying. A site with a Trust Flow close to or above its Citation Flow tends to have a smaller profile that leans on a few well-connected sources. That can describe a niche publication that a handful of respected sites cite regularly. It is not proof of quality either, but it points the other way from a profile built on volume, and it is the shape most link builders would rather see on a prospect.
Topical Trust Flow adds the dimension both headline scores miss. Majestic describes it as showing “the relative influence of a web page, subdomain or root domain in any given topic or category.” A gardening site whose Topical Trust Flow sits mostly in gambling or pharmaceuticals has a problem that no headline score will reveal. For link prospecting, that topical match is often more telling than either number.
How to check Trust Flow without overreading it
Checking the scores is the easy part: Majestic shows them for any domain, subdomain or URL you look up. Using them well takes a short routine.
- Read both numbers together. Note which is higher and by how much, rather than judging either score alone.
- Check the topic. Look at Topical Trust Flow and ask whether the categories match the site’s actual content and yours.
- Open the links behind a wide gap. A large Citation Flow lead is the cue to inspect where the links come from.
- Compare like with like. Scores mean more against similar sites in the same niche than in isolation.
- Look at the page, not just the domain. A strong root domain can host a weak page. If the link would sit on a specific URL, check that URL’s scores and its own links too.
Then make the decision on the links themselves. Our piece on whether toxic backlinks matter explains why a spammy profile is usually a sign that links are being ignored rather than a reason to panic, which is also how to read a site with a weak Trust Flow.
Third-party scores, not Google’s
Trust Flow and Citation Flow are Majestic’s metrics. Google does not use them, and a higher score does not cause better rankings. Like Domain Rating and Domain Authority, they are models of the link graph built from one vendor’s crawl. We cover the same caveat for the other big two in Domain Rating vs Domain Authority and in our piece on whether Domain Rating matters.
That is also the main limitation of this whole approach. Each score reflects what Majestic’s crawler found and how its seed set was chosen. Two tools can disagree about the same site, and neither can tell you which links Google counts. Use the Flow metrics to decide where to look, not as a substitute for looking. Pair them with the site’s actual content and estimated traffic before you commit time or money to a prospect.
Frequently asked questions
What is the difference between Trust Flow and Citation Flow?
Trust Flow is Majestic’s quality score, based on how closely a site connects to manually reviewed seed sites. Citation Flow measures the link equity or “power” a site carries, regardless of quality.
Does Google use Trust Flow?
No. Trust Flow and Citation Flow are third-party metrics from Majestic. They model the link graph but are not part of Google’s ranking systems.
Is there an ideal Trust Flow to Citation Flow ratio?
Majestic’s glossary does not set one. Treat a large gap, especially a much higher Citation Flow, as a signal to inspect the backlinks rather than as a verdict.
What is Topical Trust Flow?
A set of scores on a log-based 0 to 100 scale showing the relative influence of a page, subdomain or root domain in a given topic or category.
The takeaway Trust Flow is quality, Citation Flow is quantity, and the gap between them is the useful part. Use a wide gap or a topical mismatch as a cue to inspect the links, and remember that Google reads neither score.
