What exactly is free trust flow?
Trust flow is a score from 0 to 100 created by Majestic to evaluate how much trust the links pointing to your site deserve. Majestic builds this score from a reference list of trusted sites (institutional sites, universities, established media), then measures how close your domain sits to those trusted sources.
A link from one of these reference sites pushes your score up. A link from a network of low-quality sites barely moves it, even when the link count explodes. This logic is what separates trust flow from a simple backlink counter.
You can also cross-reference this number with Citation Flow, Majestic’s other score that measures link volume rather than quality. The ratio between the two tells you about the real health of your link profile.
How do you check your trust flow for free?
Three free methods exist to read your score without paying for a Majestic subscription. Each one fits a different use case, from a one-off check to bulk analysis.
Method 1: the Majestic Backlink Analyzer Chrome extension
The Majestic Backlink Analyzer Chrome extension stays the fastest option for a quick check while you browse. You install it once, then click its icon on any web page to display trust flow, Citation Flow, and Visibility Flow directly in the URL bar.
Without a Majestic account, you get the overall score at the URL, subdomain, and root domain level, plus a link profile chart. With a linked free account, you also unlock the Topical Trust Flow, the main topic of the links received.
- One-click install from the Chrome Web Store, also available on Firefox.
- Instant reading on any page, including competitor sites while you browse them.
- No personal data required for the base version.
Method 2: Majestic Site Explorer without an account
Majestic’s Site Explorer gives you a fuller report than a simple extension. You enter the URL to analyze, choose the level (URL, subdomain, or root domain), and the tool displays trust flow, Citation Flow, referring domain count, and link history.
The basic search works without registration. A free account unlocks a few extra searches per day and access to history, a paid subscription stays necessary to export complete backlink lists.
Method 3: third-party tools without registration
Third-party tools republish Majestic data as a quick check, useful when you need to review a list of domains without multiplying logins to your main account. These tools work for a one-off check, less so for regular tracking or a deep competitive analysis, where direct access to Majestic stays preferable.
What trust flow score counts as good?
A trust flow score always reads in context, never as an isolated value. A score of 15 can work for a recent local site, a score of 40 becomes necessary against competitors established for years.
| Trust Flow score | Interpretation | Usage context |
|---|---|---|
| 0 to 14 | Young or underdeveloped link profile | Recent site, priority on internal linking and first quality links |
| 15 to 29 | Solid base for a showcase or local site | Small businesses, freelancers, local activity |
| 30 to 39 | Solid profile for a B2B site | Established sites with regular link building activity |
| 40 and above | Strong authority, useful as a link negotiation argument | Major media, institutional sites, established brands |
A score above 30 is generally considered solid for a B2B site, though the raw number never stands alone (source: Perfoseos, June 2026). A score above 40 signals strong authority and works as an argument in link building negotiations (source: Anthedesign, June 2025). A site with a modest but perfectly on-topic trust flow often outperforms a generalist site with a higher score.
Free trust flow or paid Majestic: where are the limits?
The free version shows you the score, not the detail. You see your overall trust flow, but not the exhaustive list of links behind it, nor the bulk export needed for a complete audit.
- Free: TF and CF scores, profile chart, top ten backlinks displayed by the extension.
- Paid: unlimited backlink export, detailed Topical Trust Flow per link, multi-domain comparison, API for automation.
For a one-off check or a verification before a link exchange, the free version covers the need. For a complete link building audit or a deep competitive analysis, the subscription becomes necessary.
How do you use your trust flow in an SEO strategy?
You use trust flow at three specific moments of your link building work. Before a link exchange, you check the partner site’s score to rule out spammy profiles. During a competitive analysis, you compare your trust flow to that of sites already ranking on your keywords. During a link audit, you spot toxic backlinks whose topical score does not match your topic.
In my view, trust flow stays the most reliable indicator for arbitrating a link exchange, more than the raw number of referring domains. A site with 50 well-themed links at trust flow 25 beats a site with 500 off-topic links at trust flow 15.
The competitive analysis process fits in four steps: export competitor backlinks, filter out links without topical relevance, sort by descending trust flow, keep candidates above 20 for your prospecting sheet.
Does trust flow still measure your authority in 2026?
Trust flow only reads your inbound links, nothing about your presence in answers generated by AI engines. An Ahrefs study from March 2026 found that only 38% of citations in Google’s AI Overview come from the top ten classic results, down from 76% in July 2025. A good trust flow no longer guarantees visibility in AI answers.
In my view, trust flow keeps its value for evaluating a link profile, but a site can show a high score and stay invisible when a user asks ChatGPT or Perplexity a question. Classic SEO and visibility in generative engines get measured with two different logics.
I co-founded Cockpyt AI, a French tool that tracks brand presence in ChatGPT, Perplexity, Gemini, and Claude (tracking of Google’s AI Overview and AI Mode is under development). This dual reading, link authority on one side, presence in AI answers on the other, gives you a complete picture of your current visibility.

Frequently asked questions about free trust flow
Is trust flow an official Google ranking factor?
No. Trust flow is a proprietary Majestic metric, not an official signal confirmed by Google. It stays correlated with the authority signals Google observes, which makes it a useful proxy without being direct algorithm data.
Can you check a competitor’s trust flow for free?
Yes. Majestic’s Chrome extension and Site Explorer work on any domain, including your competitors’, with no paid account needed for the overall score.
Why is my trust flow lower than my Citation Flow?
This situation signals a link volume higher than its quality. You likely have links from low-trust sites or generic directories that inflate Citation Flow without moving trust flow up.
Does trust flow update quickly after a new link?
The update depends on the next crawl pass Majestic runs on the site linking to you and on your own site. Expect generally several weeks before a link shows up in your score.
Does a high trust flow protect against Google penalties?
A high trust flow lowers the risk of being read as a spammy link profile, without offering guaranteed protection. The topical relevance of your links matters as much as the raw score.
Is free trust flow enough for a complete link audit?
Not for an exhaustive audit. The free version shows the overall score and a preview of your best links, a Majestic subscription becomes necessary to export your entire link profile and flag every toxic link.
