What is TrustFlow and CitationFlow? (Majestic SEO Metrics Explained)
Most SEOs know Domain Authority and Domain Rating — but Majestic’s TrustFlow and CitationFlow measure something the others miss: not just how many links you have, but how trustworthy they are.
This guide explains both metrics completely — what they mean, how they’re calculated, what scores to aim for, and how they compare to Moz and Ahrefs metrics.
What Is Majestic SEO?
Before diving into the metrics, a quick context: Majestic is one of the oldest and largest backlink analysis platforms in the world. Founded in 2004, Majestic has built its own independent web crawl index — separate from Google, Moz, and Ahrefs.
Majestic’s two core metrics are:
- TrustFlow (TF) — measures the quality and trustworthiness of backlinks
- CitationFlow (CF) — measures the quantity and raw link power
These two numbers together give you a complete picture of any website’s backlink profile — one that no other tool replicates in quite the same way.
What Is TrustFlow?
TrustFlow is a score from 0 to 100 that measures how trustworthy a website’s backlink profile is, based on its proximity to a curated list of trusted seed sites.
Majestic built TrustFlow around a core insight: not all links are equal. A link from a BBC news article is fundamentally different from a link from a random blog. TrustFlow tries to quantify that difference.
How it works: Majestic maintains a list of highly trusted “seed sites” — authoritative, editorially curated websites like major universities, government domains, established news organizations, and well-known reference sites. Sites that receive links directly from these seed sites get a high TrustFlow. Sites further removed from these trusted sources get progressively lower scores.
Think of it like a trust chain:
- Seed site (BBC) → links to Site A → TF very high
- Site A → links to Site B → TF high
- Site B → links to Site C → TF moderate
- Random blog → links to Site D → TF low
Key facts about TrustFlow:
- Scale: 0 to 100
- Measures: Quality and trustworthiness of backlinks
- Created by: Majestic
- Available at: Page level (page TF) and domain level (root domain TF)
- Higher = better quality links from trusted sources
What Is CitationFlow?
CitationFlow is a score from 0 to 100 that measures the raw quantity and influence of links pointing to a website — regardless of whether those links come from trusted sources.
CitationFlow is Majestic’s equivalent of raw link power. If a page receives thousands of links from all over the internet — even low-quality ones — its CitationFlow will be high.
The key difference from TrustFlow: CitationFlow does not judge the quality of links. It counts influence. A site linked from ten thousand spammy forums will have a high CitationFlow. A site linked from five BBC articles will have a high TrustFlow. These are completely different things.
Key facts about CitationFlow:
- Scale: 0 to 100
- Measures: Volume and raw influence of links
- Does NOT distinguish between high-quality and low-quality links
- Higher CF does not automatically mean better SEO value
- Most useful when read alongside TrustFlow
TrustFlow vs CitationFlow — The Relationship Between Them
The real power of these metrics comes from reading them together. The ratio between TF and CF tells you something critically important about a site’s link profile.
The TF:CF ratio:
| TF: CF Ratio | What It Means |
|---|---|
| TF close to CF (ratio near 1) | Healthy link profile — links are both numerous and trustworthy |
| TF much lower than CF | Suspicious — lots of links but most are low-quality or spammy |
| TF higher than CF | Excellent — site has fewer but highly trusted links |
| CF very high, TF near zero | Red flag — likely spam links or link farm activity |
Practical example:
- Site A: TF 35, CF 38 → Ratio 0.92 → Healthy profile
- Site B: TF 12, CF 45 → Ratio 0.27 → Many low-quality links, possible spam
- Site C: TF 40, CF 30 → Ratio 1.33 → Excellent — trusted links outweigh volume
For link building and competitor analysis, always look at the TF:CF ratio, not just the individual numbers.
TrustFlow Score Ranges — What They Mean
| TrustFlow Score | What It Indicates |
|---|---|
| 0 – 10 | New or barely linked site — minimal trust signals |
| 10 – 20 | Low trust — few quality backlinks |
| 20 – 35 | Developing — some legitimate link building happening |
| 35 – 50 | Solid — good quality backlink profile |
| 50 – 65 | Strong — well-established site with trusted links |
| 65 – 80 | Very strong — major niche authority with high-trust backlinks |
| 80 – 100 | Elite — Wikipedia, BBC, government domains |
Most legitimate small-to-medium websites fall between TF 15 and TF 40. Reaching TF 30+ is a meaningful milestone that indicates a genuinely trustworthy backlink profile.
CitationFlow Score Ranges — What They Mean
| CitationFlow Score | What It Indicates |
|---|---|
| 0 – 10 | Very few links — new or small site |
| 10 – 25 | Low link volume — modest presence |
| 25 – 40 | Moderate — growing link profile |
| 40 – 55 | High — well-linked site |
| 55 – 70 | Very high — large link volume |
| 70 – 100 | Massive link volume — major publications or link-farm activity |
A high CitationFlow alone means nothing without context. Always check TrustFlow alongside it.
Topical TrustFlow — What It Is and Why It Matters
Majestic goes one step further with a concept called Topical TrustFlow — breaking down TrustFlow by topic category.
Instead of just giving a site a single TrustFlow number, Majestic assigns trust scores across 27 topic categories. This shows you not just how trustworthy a site’s backlinks are, but which topics those trusted backlinks come from.
Why this matters for link building:
A backlink carries more value when it comes from a topically relevant source. If your site is about SEO and digital marketing, a TrustFlow of 35 in the “Computers/Internet/Searching” category is more valuable than a generic TF 35 from a mix of unrelated topics.
Topical TrustFlow categories include:
- Computers / Internet / Searching
- Business / Industries
- Arts / Entertainment
- Health / Fitness
- News / Media
- Education / Reference
- (and 21 more)
When evaluating a potential link partner, check their Topical TrustFlow. A site with TF 40 in your specific niche category is far more valuable than a TF 40 site whose trust comes entirely from an unrelated category.
How TrustFlow and CitationFlow Are Calculated
TrustFlow calculation: Majestic starts with its curated seed list of highly trusted domains. Every page that receives a link from a seed site gets a TrustFlow score. That score then propagates outward — pages receiving links from high-TF pages inherit a portion of that trust, with diminishing intensity at each step removed from the seed.
The further a site is from the trusted seed sources, the lower its TrustFlow. Spam sites that have never received links from any trusted source will have a TrustFlow near zero — no matter how many links they have.
CitationFlow calculation: CitationFlow uses a similar propagation model to TrustFlow — but without the trust requirement. It measures raw link influence across Majestic’s entire web index, including links from all sources regardless of quality. The calculation is iterative: every page’s CF depends on the CF of pages linking to it.
The important technical distinction: TrustFlow is gated by the seed list — trust can only flow from trusted sources. CitationFlow is ungated — influence flows from everything. This is why they diverge on sites with many low-quality links.
TrustFlow vs Domain Authority vs Domain Rating
Most SEO professionals use multiple tools. Here is how Majestic’s metrics fit alongside the ones you already know:
| Metric | Tool | Measures | Scale |
|---|---|---|---|
| TrustFlow (TF) | Majestic | Trust quality of backlinks | 0 – 100 |
| CitationFlow (CF) | Majestic | Raw link volume/influence | 0 – 100 |
| Domain Authority (DA) | Moz | Predicted ranking ability (link quality + quantity + ML) | 1 – 100 |
| Domain Rating (DR) | Ahrefs | Overall site backlink strength | 0 – 100 |
| Spam Score | Moz | Likelihood of spam penalties | 0 – 100% |
Which should you use?
Each tool has a different crawl index and methodology — so they often show different numbers for the same site. Rather than picking one, use them together:
- TrustFlow → Check link quality and trust (best spam detector among the three)
- DA → Check ranking prediction and overall authority
- DR → Check raw backlink strength with Ahrefs’ larger index
A site that scores well across all three — high TF, low CF:TF gap, good DA, good DR — has the strongest, most genuinely trustworthy backlink profile.
How to Check TrustFlow and CitationFlow for Free
Majestic offers limited free access to TF and CF data. Here are your options:
Option 1 — Majestic.com free search: Go to majestic.com and enter any domain. Without an account, Majestic shows basic TF and CF scores for the root domain. You get a limited number of free searches per day.
Option 2 — Majestic free account: Creating a free Majestic account provides slightly more data access — including some referring domain details and Topical TrustFlow breakdowns.
Option 3 — Third-party tools: Some free SEO browser extensions display Majestic TF and CF alongside other metrics like DA and DR. The MozBar and similar extensions sometimes integrate Majestic data.
Option 4 — Majestic’s free bulk checker. Majestic allows limited bulk TF/CF checks through their interface. For checking multiple domains quickly (for outreach vetting or competitor analysis), this is faster than checking one by one.
Practical Uses of TrustFlow and CitationFlow in SEO
1. Vetting guest post opportunities: Before accepting or pitching a guest post, check the site’s TF and TF: CF ratio. A TF below 10 or a CF far exceeding TF suggests the site has a spam-heavy link profile. A link from such a site may carry little value — or even trigger negative associations.
Target minimum for guest post sites: TF 15+, TF: CF ratio above 0.5
2. Evaluating link building targets: When building your outreach list, TF is a strong filter for link quality. Sites with TF 25+ in your niche topic category are worth prioritizing.
3. Competitive backlink analysis: Check competitors’ TF and CF to understand whether their authority was built through quality link building or through volume-heavy (potentially spammy) tactics. A competitor with CF 55 but TF 18 built their links in ways that may be risky to replicate.
4. Auditing your own link profile: Check your own domain’s TF and CF regularly. A rising CF without a corresponding TF increase suggests you are acquiring low-quality links — which could signal a worsening link profile even if your raw backlink count is growing.
5. Identifying toxic backlinks: Links from pages with very low TF (below 5) and high CF are classic spam signals. These are the links worth including in a disavow file if you are cleaning up a penalized site.
How to Improve Your TrustFlow Score
Improving TrustFlow requires earning links from sites that are themselves close to Majestic’s trusted seed sources. In practice, this means targeting high-authority, editorially curated sites.
What moves TrustFlow:
- Links from government and educational domains (.gov, .edu)
- Links from major news publications (BBC, Reuters, industry trade publications)
- Links from established industry associations
- Editorial links from high-DA, high-TF blogs in your niche
- Links from Wikipedia or reference sites (difficult but powerful)
What does not move TrustFlow (and can hurt TF: CF ratio):
- Directory submissions on low-quality sites
- Forum profile links
- Comment spam
- Press release distribution to low-quality newswires
- Paid links from link farms
The pattern is consistent: TrustFlow rewards exactly the same link building behaviors that Google rewards — earn links from genuinely authoritative, editorially driven sources.
Summary — Key Takeaways
- TrustFlow measures link quality and trust proximity to authoritative seed sites — higher is better
- CitationFlow measures raw link volume and influence — high CF without matching TF is a warning sign
- The TF: CF ratio is the most useful single indicator of backlink profile health — aim for a ratio close to 1 or above
- Topical TrustFlow adds niche relevance to the trust measurement — links from your specific topic category carry more value
- TrustFlow complements DA and DR — use all three together for the most complete authority picture
- To improve TrustFlow, earn editorial links from genuinely authoritative, trusted sources in your niche
Frequently Asked Questions (FAQ)
What is TrustFlow in SEO?
TrustFlow is a Majestic metric (0–100) that measures how trustworthy a website’s backlinks are, based on proximity to a curated list of highly trusted seed sites like major universities, government domains, and established news organizations. Higher TrustFlow means links come from more trusted sources.
What is CitationFlow in SEO?
CitationFlow is a Majestic metric (0–100) that measures the raw volume and influence of links pointing to a website, regardless of their quality. A high CitationFlow means many links exist — but says nothing about whether those links are trustworthy or spammy.
What is a good TrustFlow score?
TrustFlow above 20 is considered decent for small-to-medium websites. TrustFlow 35 to 50 indicates a solid, legitimate backlink profile. TrustFlow above 50 is strong and typical of established authority sites. Most new sites start near 0 and build TrustFlow gradually through quality link acquisition.
What does the TrustFlow to CitationFlow ratio mean?
The TF: CF ratio indicates link quality relative to quantity. A ratio near 1 (TF and CF are similar) means the site has both volume and quality — healthy. A ratio below 0.5 (CF much higher than TF) means many links exist, but most are low-quality. A ratio above 1 (TF exceeds CF) is excellent, meaning the site’s links are highly trusted.
How is TrustFlow different from Domain Authority?
TrustFlow (Majestic) specifically measures trust proximity to authoritative seed sites — it focuses entirely on link quality. Domain Authority (Moz) is a machine-learning prediction of ranking likelihood that combines multiple signals. They often show similar patterns but can differ significantly, especially for sites with many low-quality links (high CF, low TF, but potentially inflated DA).
Can I check TrustFlow for free?
Yes. Majestic.com allows a limited number of free domain searches showing basic TF and CF scores. Creating a free Majestic account expands access slightly. Some SEO browser extensions also display Majestic TF and CF data alongside other metrics.
What is Topical TrustFlow?
Topical TrustFlow breaks down a site’s TrustFlow score across 27 topic categories. Instead of one overall trust number, you see which topics a site’s trusted links come from. A high Topical TrustFlow in your specific niche category indicates the site has trusted authority specifically relevant to your topic area.
How do I improve my TrustFlow?
Earn links from sites that are themselves close to Majestic’s trusted seed sources — major publications, government sites, educational institutions, established industry authorities. Every editorial link from a high-TF site passes a portion of trust to your domain. Spammy link building raises CitationFlow but not TrustFlow, worsening your TF: CF ratio.
Is TrustFlow or Domain Authority more important for SEO?
Both measure different things, and neither is universally more important. TrustFlow is the best indicator of link quality and spam risk. Domain Authority better predicts ranking performance by incorporating multiple signals. For backlink vetting, TrustFlow is often more decisive. For overall SEO strategy and competitive analysis, DA and DR are more commonly used industry benchmarks.
