Trust Flow: What It Means and How to Improve It

Trust Flow is a 0 to 100 score from the backlink tool Majestic that estimates the quality of the links pointing to a URL, subdomain or domain. Majestic builds it from a seed set of human-curated sites and follows their links outward, so the closer your site sits to trusted sites in the link graph, the higher your score. It is not a Google metric, and raising it on its own will not lift your rankings.

This guide is for e-commerce and Shopify teams who see Trust Flow in an SEO report, a link vendor pitch or a competitor audit and want to know what it actually tells them. You'll learn how Majestic calculates it, how to read it next to Citation Flow, how it compares with Domain Rating and Domain Authority, what Google itself says about links, and a step-by-step process for earning the kind of links that lift Trust Flow as a side effect.

What is Trust Flow?

Majestic's glossary defines Trust Flow as "a score based on quality, on a scale between 0-100." Majestic's FAQ puts it more simply: Trust Flow represents the authority of a link, while its sister metric, Citation Flow, represents the popularity of a link. Majestic reports both at URL, subdomain and root domain level, so you can score a single product page as well as a whole store.

Trust Flow belongs to a family Majestic calls Flow Metrics. According to Majestic's Flow Metric scores page, the family currently includes:

• Trust Flow: link quality, based on proximity to curated seed sites.
• Citation Flow: link quantity and influence, regardless of quality.
• Topical Trust Flow: Trust Flow broken down by topic, such as Shopping or Health.
• Visibility Flow: a newer, link-level score that tries to favor editorial links over directory-style links. Majestic says it is under active development.
• Search Flow: listed by Majestic as part of the family.

Majestic's glossary says Flow Metric scores use a logarithmic scale. In practice that means each extra point is harder to earn than the last. Moving from 10 to 20 is far easier than moving from 50 to 60, so judge progress by the trend and by competitors, not by the raw jump.

How Majestic calculates Trust Flow

Majestic has not published the full formula, but its documentation explains the idea. In its words, the algorithms "work on the basis that websites from a seed set of human-curated sites are likely to link to other human-curated quality content." Those pages in turn link to more quality content, and Majestic models that flow across its web map to produce a score for every URL and domain it has crawled.

The logic is similar to the original PageRank idea: a link passes more value when it comes from a page that itself has strong, trusted links. A link from a site that a curated seed site links to directly is worth more than a link from a site five hops away from any trusted source.

Fresh Index vs Historic Index

Majestic calculates Flow Metrics separately for its two link indexes, so the same domain can show two different Trust Flow scores. According to Majestic's FAQ, the Fresh Index contains backlinks seen in the past 120 days and updates daily, while the Historic Index contains links seen since 2006. Majestic's site footer showed the Historic Index's last update as May 3, 2024, covering crawl data through March 26, 2024. For day-to-day work, use the Fresh Index. It reflects the links you have now, not links that may have disappeared years ago.

Majestic says Flow Metrics are recalculated on every index update. That is why a score can move even when you haven't gained or lost a link: the sites linking to you gained or lost links, and the value flowing through them changed.

Trust Flow vs Citation Flow

Citation Flow is the other half of the pair. Majestic's Flow Metric page says Citation Flow "reflects the quantity of links that point to any given website" and "does not care whether a link is of good-quality, or poor quality." It still looks at the wider link network rather than raw backlink counts, but it rewards volume.

Majestic is clear that the two are designed to be used together. Because the web contains so much low-quality, machine-generated linking, Majestic notes that "it is very rare for a website to have a larger Trust Flow than Citation Flow." Its own examples of exceptions are elite university domains.

For a normal store, a Trust Flow somewhat below Citation Flow is expected. What you are watching for is a wide gap. Majestic's July 2023 guide to reading Trust Flow charts says that, in theory, sites with higher Trust Flow than Citation Flow "should have a higher proportion of high quality links." The reverse also holds: a site with a large Citation Flow and a tiny Trust Flow has many links, but few of them trace back to trusted sources.

The TF/CF ratio

Many SEOs divide Trust Flow by Citation Flow to get a single ratio. Majestic does not publish an official ratio or a pass mark, and its FAQ talks about the difference (the "delta") between the two scores instead. Treat any rule of thumb you read, such as "aim for a ratio above 0.5," as a heuristic, not a Majestic standard. The illustrative example below shows why the ratio is useful for spotting patterns across a list of sites.

Store B has the highest Citation Flow of the four, yet its Trust Flow is low. That is the classic pattern of a profile built from directories, comment links or a link network. It is exactly the kind of site you would not want a link from, and if it is your own site, it is a reason to audit your backlinks.

Topical Trust Flow and why relevance matters

A link from a respected cooking site matters more to a cookware store than a link from a respected car blog. Topical Trust Flow is Majestic's attempt to measure that. According to Majestic, instead of treating the seed set as one pool, the Topical Trust Flow algorithm uses "over 800 pools of sites" that have been identified and classified by topic, and passes along both a strength signal and a topic classification as it follows links.

The result is a list of topics for each site, with a score for each, such as Shopping/Clothing or Health/Nutrition. Majestic's glossary says Topical Trust Flow shows "the relative influence of a web page, subdomain or root domain in any given topic or category" on a log-based scale from 0 to 100.

How e-commerce teams can use it

• Vet link prospects. A site whose top topic matches your category is a better target than one with a higher overall Trust Flow in an unrelated topic.
• Spot off-topic profiles. If your supplement store's top topics are Gambling or Adult, something is wrong with your link profile.
• Check your positioning. Your own top topic should match what you sell. If it does not, your best links may be coming from the wrong neighborhood.

Majestic's own documentation describes quality links from relevant websites as "thought to be a significant ranking factor" in full text search engines, which is careful wording. Google's own guidance focuses on whether links are editorial and relevant, which lines up with the idea even though Google does not use Majestic's numbers.

Trust Flow vs Domain Rating and Domain Authority

Trust Flow is one of three third-party link scores you will see in most SEO reports. All three try to estimate link strength, and none of them is used by Google. They are built from different crawlers and different math, so the numbers are not interchangeable.

Ahrefs' help center says DR "shows the strength of a website's backlink profile compared to the others in our database on a 100-point scale," and that it correlates with rankings less well than its page-level URL Rating. For a full breakdown of Ahrefs' metric, read our guide to what Domain Rating is, and for Moz's score see what DA means.

The practical rule: pick one tool as your system of record, track it monthly, and compare yourself with your direct competitors in that same tool. Mixing a Majestic Trust Flow of 30 with an Ahrefs DR of 45 tells you nothing.

Does Trust Flow affect Google rankings?

No, not directly. Majestic says so plainly on its own Flow Metric page: "As Majestic Flow Metric scores do not directly influence search engines, there is little to be gained in and of its self by seeking to enhance your Trust Flow or Citation Flow." Google has its own link signals and has never said it uses any third-party score.

What Google does say is that links matter. Its documentation on making links crawlable says Google uses links to judge how relevant pages are and to discover new pages to crawl. Its spam policies define link spam as "the practice of creating links to or from a site primarily for the purpose of manipulating search rankings." And since December 2022, Google has said it uses SpamBrain, its AI-based spam prevention system, to "neutralize the impact of unnatural links," including detecting sites that buy links and sites that exist to pass outgoing links.

So Trust Flow is a proxy. When it rises because trusted, relevant sites started linking to you, that usually coincides with better rankings, because Google values the same links. When it rises because someone sold you a package of "high TF links," you have paid for a number Google ignores, and possibly for links that break its policies.

How to check your Trust Flow

You need Majestic, or a tool from one of the small number of authorized resellers Majestic licenses its Flow Metric data to, to see Trust Flow. Here is a simple monthly check:

1. Look up your root domain in Majestic Site Explorer and switch to the Fresh Index so you see current links.
2. Record Trust Flow and Citation Flow for the root domain, your www subdomain and your top three revenue pages. Note the date, since Fresh Index scores move daily.
3. Check Topical Trust Flow and confirm your top topic matches your product category.
4. Open the referring domains report and sort by Trust Flow to see which sites contribute the most. These are the relationships worth protecting.
5. Run the same check on three competitors that outrank you for your main category keywords. Note which trusted sites link to them but not to you.
6. Repeat monthly and chart the trend in a sheet next to organic sessions and revenue, so the link metric always sits beside the numbers that matter.

While you are in the referring domains list, check how those sites link to you. Our anchor text analyzer helps you spot over-optimized anchors, and our guide to anchor text SEO explains what a natural mix looks like.

How to improve Trust Flow in 6 steps

Majestic's own advice is that good, white hat SEO should increase your site's authority and, as a consequence, your Flow Metric scores. In its words, any increase "should be seen as a celebration of your success, rather than the cause of it." These six steps follow that principle: earn links Google values, and Trust Flow follows.

1. Find the trusted sites in your niche. Use Topical Trust Flow to list the highest-scoring sites in your category: trade associations, respected publications, universities with relevant programs, and established review sites. These are your targets, because links from them sit close to the seed set.
2. Build one asset worth linking to. Original data, a sizing or compatibility guide, a care guide or a calculator earns links far more often than a product page. Ask what a journalist or blogger in your space would need to cite.
3. Do outreach and digital PR. Pitch the asset to the specific writers who cover your topic. Majestic's own guidance names good content and effective digital PR as the way to build authority. Our guide to link building covers outreach methods in detail.
4. Claim the links you have already earned. Search for brand mentions that do not link to you and ask the writer to add a link. Our post on unlinked brand mentions walks through the process.
5. Strengthen internal linking. Trust Flow is calculated at URL level too. Link from the pages that earn external links to the collection and product pages you want to rank, so value reaches pages that make money. Our internal link checker shows which pages are under-linked.
6. Stop, do not chase, low-quality links. Cancel any link packages, remove sitewide footer links you control on partner sites, and avoid link exchanges done purely for cross-linking, which Google lists as link spam. You do not need to disavow every low-quality link: Google says that in most cases it can assess which links to trust without help.

A note on link attributes: Google treats nofollow, sponsored and ugc as hints, so a nofollow link from a trusted publication can still be valuable for traffic and discovery. Our guide to dofollow backlinks explains the difference.

Trust Flow mistakes to avoid

Most problems with Trust Flow come from treating it as a goal instead of a measurement.

• Buying links by metric. A seller's screenshot showing TF 40 says nothing about whether Google trusts the site. Many link networks are built to look good in third-party tools.
• Comparing across tools. Majestic, Ahrefs and Moz crawl different parts of the web. Compare like with like.
• Reading the Historic Index as current. The Historic Index includes links that may have disappeared long ago. Use the Fresh Index for decisions.
• Ignoring topic. A high overall Trust Flow from off-topic sites helps less than a modest score from sites in your category.
• Panicking over small drops. Scores are recalculated on every index update, and the logarithmic scale exaggerates movement at the low end. Look at a three-month trend and your organic revenue before acting.
• Using the disavow tool by reflex. Google's disavow documentation calls it an advanced feature that, if used incorrectly, "can potentially harm your site's performance in Google Search results." It is meant for sites with a manual action for unnatural links, or a clear set of spammy links you cannot get removed.

Where to start this week

Pull your Fresh Index Trust Flow, Citation Flow and top topics, then do the same for three competitors. If your Citation Flow far outruns your Trust Flow, review your referring domains before you build anything new. If both are low, pick one linkable asset you can publish in the next month and build an outreach list from the trusted sites in your topic.

Track the result against organic sessions and revenue, not the score alone. If you want help turning that into a plan for your store, our SEO services team can benchmark your link profile against the competitors you are losing to, or you can get in touch.
