Trust Flow and Citation Flow: The Majestic domain link-quality metrics explained
Trust Flow and Citation Flow are two Majestic metrics that score a domain link profile from 0 to 100: Trust Flow measures link quality by proximity to a curated set of trusted seed sites, and Citation Flow measures link volume and influence regardless of quality.
The TF:CF ratio is the spam signal practitioners read first, because a low ratio (high Citation Flow against low Trust Flow) exposes a profile built on volume without matching trust.
SEO Domains operates the curated marketplace with a 220,000+ pre-screened catalogue from $100 entry-level domains through $1.5 million premium acquisitions. Every listing surfaces Domain Authority and Domain Rating alongside Trust Flow and Citation Flow, screened through the catalogue 7-vector inheritance check. Each Majestic reading is cross-validated before acquisition instead of taken on its own.
What are Trust Flow and Citation Flow
Trust Flow and Citation Flow are two Majestic Flow Metrics that score a domain link profile from 0 to 100. Trust Flow rates link quality by trust-seed proximity. Citation Flow rates link volume and influence.
Majestic introduced the pair around 2012, replacing the older ACRank link-scoring metric.
The two scores are read together. One number describes how trusted the linking profile is. The other describes how large it is.
| Flow Metric | What it measures | Scale | Vendor |
|---|---|---|---|
| Trust Flow | Link quality by proximity to a curated set of trusted seed sites | 0-100 | Majestic |
| Citation Flow | Link volume and influence regardless of link quality | 0-100 | Majestic |
| TF:CF ratio | The trust-to-volume balance that exposes spam | Derived | Majestic |
| Topical Trust Flow | Category-level trust across the Majestic topic taxonomy | 0-100 per topic | Majestic |
Majestic calculates both Flow Metrics from the same crawled link graph.
Majestic crawls the web and maps the link relationships between domains.
Citation Flow counts the links and weights them by the influence of the linking pages; Trust Flow weights the same links by how close each linking site sits to a curated set of trusted seeds.
Both readings come from one link graph, so a wide gap between them is meaningful and not a measurement artifact.
The Flow Metrics replaced ACRank as the Majestic link-scoring standard.
ACRank counted citations without separating trust from volume, so a profile padded with low-value links scored as well as a profile earned from authoritative sources.
Majestic split the single score into Trust Flow and Citation Flow around 2012 to expose that difference.
The split is the reason a domain with strong Citation Flow and weak Trust Flow now reads as a warning instead of a strength.
Trust keeps pace with volume, so the TF:CF ratio sits near or above 0.5. Links were earned from authoritative sources.
Few links, but the ones that exist come from trusted sources. The ratio stays healthy on a smaller profile.
Citation Flow runs far ahead of Trust Flow, so the ratio falls below 0.5. The link-farm and bulk-directory signature.
Neither trust nor volume registers. A new or near-empty link profile with little to read either way.
Trust Flow: link quality by trust-seed proximity
Trust Flow is the Majestic metric that scores link quality from 0 to 100 by measuring how close a domain sits to a curated set of trusted seed sites in the link graph. The closer a domain sits to trusted seeds, the higher its Trust Flow.
The seed set anchors the score to editorially trusted sources. Trust Flow rises when authoritative domains link to a profile. It stays flat when low-value domains link to it.
Trust-seed proximity is the mechanism behind the Trust Flow score.
Majestic propagates trust outward from the curated seed set across the link graph.
A domain linked directly by a trusted seed sits one step away and inherits strong Trust Flow; a domain linked only by sites 3 or 4 steps removed from any seed inherits weak Trust Flow.
The distance from the trusted seeds, not the raw count of links, is what the Trust Flow number records.
A high Trust Flow reflects links earned from authoritative sources.
A profile carrying Trust Flow in the upper brackets earned links from domains the seed set treats as trusted, which compounds into a high score.
Charles Floate has documented across PBN A/B testing through 2018 to 2024 that Trust Flow resists inflation from volume tactics, because adding low-trust links raises Citation Flow without moving Trust Flow.
The resistance is what makes Trust Flow the quality half of the Majestic pair.
Aged-domain buyers read Trust Flow as the inherited-trust signal.
An aged domain carrying genuine Trust Flow inherited that score from authoritative links built over its history. Buyers reading Trust Flow check that the score traces to trusted linking sources instead of to a volume spike.
The SEO Domains catalogue verifies the trusted-source provenance behind the Trust Flow reading through the 7-vector inheritance screen before a listing reaches buyers.
Citation Flow: link volume and influence
Citation Flow is the Majestic metric that scores link volume and influence from 0 to 100 regardless of link quality. The score rises with the number and influence of pages pointing to a domain. It does not separate a trusted link from an untrusted one.
Citation Flow answers how large and how connected a link profile is. Trust Flow answers how trusted it is.
Citation Flow counts link volume without a quality filter.
Citation Flow treats a link from a trusted news outlet and a link from a link farm as both contributing to volume.
The metric was built to measure connectivity, so a profile with 50,000 links from low-value sources can post a high Citation Flow.
The absence of a quality filter is the design intent, not a flaw, because the quality dimension lives in Trust Flow.
Citation Flow read alone overstates a thin or manipulated profile.
A domain showing Citation Flow 55 against Trust Flow 8 carries link volume that no trusted source backs. Reading Citation Flow in isolation rates that profile as strong; reading it against Trust Flow exposes the gap.
Cyrus Shepard at Zyppy has documented across correlation analysis through 2022 to 2024 that volume metrics overstate profiles that trust-weighted metrics correct. Citation Flow earns its value only when paired with Trust Flow.
The TF:CF ratio as the spam signal
The TF:CF ratio divides Trust Flow by Citation Flow, and the result is the spam signal practitioners read first. A healthy profile sits near or above 0.5. A low ratio of high Citation Flow against low Trust Flow signals spammy volume.
The ratio collapses the two Flow Metrics into one trust-to-volume balance.
A ratio near or above 0.5 marks a trust-backed link profile.
When Trust Flow keeps pace with Citation Flow, the trust earned from authoritative sources scales with the link volume. The 0.5 floor is the practitioner benchmark for an organic profile.
Charles Floate has documented the inflate-then-detect pattern across PBN A/B testing through 2018 to 2024: a manufactured profile lifts Citation Flow first and leaves Trust Flow behind, which drives the ratio below the floor.
A low TF:CF ratio exposes Citation-Flow volume without matching Trust Flow.
A domain holding Citation Flow 50 against Trust Flow 8 built link volume from sources the trust-seed graph does not endorse. The low ratio is the signature of three manipulation tactics:
- Link farming that manufactures citation volume from networked sites.
- Bulk directory submission that adds untrusted links at scale.
- Automated comment spam that inflates the count without earning trust.
Aged-domain buyers read the ratio before the absolute scores. The ratio catches the inflated profile that a high Citation Flow alone would disguise.
The SEO Domains 7-vector inheritance screen rejects listings whose ratio falls into the spam band.
Topical Trust Flow: category-level trust
Topical Trust Flow is the Majestic metric that assigns category-level trust, scoring which topics a domain earns its trust from across the Majestic topic taxonomy. Trust Flow gives one overall quality score. Topical Trust Flow breaks that trust into themed categories.
A domain reads strong in the topics its trusted links cover and weak in the topics they do not. The category breakdown turns a single trust number into a map of where the trust came from.
Topical Trust Flow maps each domain to the Majestic topic taxonomy.
Majestic organises trust into a topic taxonomy, and Topical Trust Flow records a 0-to-100 score per topic for a domain based on the themed links pointing to it.
A domain linked by trusted finance sources scores high in Finance and low in unrelated topics. The per-topic scores reveal whether a domain trust matches the subject a buyer intends to build on.
Category-level trust separates relevant authority from generic authority.
A domain with overall Trust Flow 40 earned entirely from health publishers carries health-relevant trust, not finance-relevant trust. Topical Trust Flow surfaces that distinction so a finance project does not inherit trust earned in an unrelated category.
Constantin Oesterling has documented across guest-posting authority audits through 2021 to 2024 that topical relevance, not raw authority, drives the value of an inherited link profile.
The SEO Domains catalogue reads Topical Trust Flow so a listing trust profile aligns with the buyer intended niche.
Trust Flow compared with Domain Authority and Domain Rating
Trust Flow is a Majestic trust-weighted quality metric, Domain Authority is a Moz machine-learning ranking proxy, and Domain Rating is an Ahrefs referring-domain strength score. The three measure the link graph from different angles and are read together instead of substituted.
Domain Authority and Domain Rating estimate overall link-graph strength. Trust Flow adds the trust dimension. Citation Flow adds the volume dimension.
Agreement across the set raises confidence. A Trust Flow that lags a high Domain Authority or Domain Rating flags a volume-heavy profile.
| Metric | Vendor | Measures | Scale |
|---|---|---|---|
| Trust Flow | Majestic | Link quality by trust-seed proximity | 0-100 |
| Citation Flow | Majestic | Link volume and influence | 0-100 |
| Domain Authority | Moz | Machine-learning ranking proxy on the Mozscape link graph | 1-100 |
| Domain Rating | Ahrefs | Recursive referring-domain strength | 0-100 |
Trust Flow adds the quality dimension that single ranking-proxy scores compress.
Domain Authority and Domain Rating fold link quality and volume into one strength estimate.
Trust Flow and Citation Flow keep the two dimensions separate, so a profile that posts a respectable Domain Rating can still expose a weak TF:CF ratio.
Cyrus Shepard at Zyppy has documented across correlation analysis through 2022 to 2024 that vendor metrics correlate on strength while diverging on trust, and the divergence is the diagnostic value of running them side by side.
A disagreement across the metric set flags a profile for manual review.
A domain reading Domain Rating 55 and Trust Flow 10 carries referring-domain volume that the trust-seed graph does not endorse, the same gap the TF:CF ratio exposes.
Practitioners cross-validate Trust Flow and Citation Flow with Domain Authority and Domain Rating precisely to catch this disagreement.
The SEO Domains catalogue surfaces all four metrics per listing, so a buyer reads the agreement or the gap across vendors in one view instead of trusting any single score.
The Majestic Fresh Index versus Historic Index
Majestic operates two link indexes that feed the Flow Metrics: the Fresh Index, updated daily for the current link picture, and the Historic Index, the long-term archive of a domain link history. The Fresh Index registers recent link gains and losses. A Trust Flow or Citation Flow reading from it reflects the current profile.
The Historic Index records links across the domain lifetime. It surfaces the full history a recent reading alone would miss.
| Index | Refresh cadence | Coverage | Read for |
|---|---|---|---|
| Fresh Index | Updated daily | The current link picture | The live Trust Flow and Citation Flow reading |
| Historic Index | Long-term archive | The domain link history | The full link history behind an aged domain |
The Fresh Index refreshes daily for the current Flow Metric reading.
Majestic updates the Fresh Index every day, so the Trust Flow and Citation Flow it reports track recent changes in the link profile. A domain that gains or loses trusted links registers the shift in the daily refresh.
Practitioners monitoring a live link-building campaign read the Fresh Index because it reflects the current state instead of a stale snapshot.
The Historic Index preserves the full link history behind an aged domain.
The Historic Index archives the links a domain accumulated across its lifetime, including links the Fresh Index no longer shows.
Aged-domain buyers read the Historic Index to see whether a Trust Flow reading rests on a long-built profile or a recent spike.
The SEO Domains catalogue cross-references both indexes at inventory ingestion, so a listing Trust Flow is verified against the domain full link history instead of a single daily reading.
5 frequently asked questions about Trust Flow and Citation Flow
The 5 top questions practitioners and aged-domain buyers ask about Trust Flow and Citation Flow. Answers reflect the SEO Domains analytical position alongside documented industry-leader interpretation, with every reading anchored to the Majestic Flow Metrics.
Q1What is the difference between Trust Flow and Citation Flow?
Trust Flow measures link quality by proximity to a curated set of trusted seed sites, while Citation Flow measures link volume and influence regardless of quality. Both are Majestic metrics scored from 0 to 100.
Trust Flow rises when authoritative domains link to a profile; Citation Flow rises with the count and influence of links, trusted or not.
Q2What is a good TF:CF ratio?
A healthy TF:CF ratio sits near or above 0.5, meaning Trust Flow keeps pace with Citation Flow.
A ratio below 0.5, driven by high Citation Flow against low Trust Flow, signals a volume-inflated profile and warrants a manual review of the linking sources. A ratio at or above 0.9 marks a trust-led profile.
Q3Are Trust Flow and Citation Flow a Moz or an Ahrefs metric?
Trust Flow and Citation Flow are Majestic metrics, not Moz and not Ahrefs. Moz produces Domain Authority and Ahrefs produces Domain Rating.
Majestic introduced Trust Flow and Citation Flow around 2012, replacing the older ACRank. Practitioners cross-validate the Majestic pair with Domain Authority and Domain Rating.
Q4What is Topical Trust Flow?
Topical Trust Flow is the Majestic metric that assigns category-level trust across the Majestic topic taxonomy, scoring which topics a domain earns its trust from.
A domain linked by trusted finance sources scores high in Finance and low in unrelated topics. Topical Trust Flow shows whether a domain trust matches the intended subject.
Q5How frequently do Trust Flow and Citation Flow update?
The Majestic Fresh Index updates daily, so the Trust Flow and Citation Flow it reports track recent link changes. The Historic Index archives the domain full link history instead of refreshing daily.
Aged-domain buyers read the Fresh Index for the current score and the Historic Index for the link history behind it.
How aged-domain buyers read Trust Flow and Citation Flow at the SEO Domains marketplace
Aged-domain buyers read Trust Flow and Citation Flow as an inherited-trust signal, checking the TF:CF ratio and Topical Trust Flow before the absolute scores so a volume-inflated profile does not pass as genuine authority. Each Majestic reading maps to a catalogue screening criterion.
The Majestic reading becomes a verification step the catalogue has already run. The map below pairs each reading with the screen it triggers.
| Flow Metric reading | What the buyer checks | Catalogue screening criterion |
|---|---|---|
| Trust Flow | Trust traces to authoritative linking sources | Trusted-source provenance in the 7-vector inheritance screen |
| TF:CF ratio | Ratio sits near or above 0.5 | Spam-band listings rejected at inventory ingestion |
| Topical Trust Flow | Trust concentrates in the buyer target niche | Topical relevance check against the intended subject |
| Historic Index reading | Trust built over the domain lifetime, not a spike | Full link-history cross-reference at ingestion |
The catalogue surfaces Trust Flow and Citation Flow alongside Domain Authority and Domain Rating per listing.
SEO Domains catalogue listings show Trust Flow and Citation Flow next to Domain Authority and Domain Rating, so a buyer reads the trust dimension, the volume dimension, and the cross-vendor strength estimate in one view.
A high Domain Rating paired with a weak Trust Flow flags a volume-heavy profile before acquisition. The four-metric read offsets the risk that any single score disguises a manipulated link profile.
ICANN-accredited transfer preserves the Majestic Flow Metrics through ownership change.
SEO Domains operates with ICANN-accredited registrar transfer protocols.
Majestic records link profiles by hostname and propagates the inherited Trust Flow and Citation Flow to the new owner without re-validation, alongside the parallel Moz Domain Authority and Ahrefs Domain Rating.
Buyers acquire the trust-backed Flow Metric profile that the catalogue 7-vector inheritance screen verified against the spam-band ratio and the Historic Index at inventory ingestion.
