…But they are not the same thing.
The simple answer, no, Domain Trust is not the same as Domain Authority. They measure different things, come from different SEO tools, and neither should be treated as a direct Google ranking factor.
However, that doesn’t mean they lack strengths for analysis. When understood properly, both can help you make better decisions about your website, your backlink profile, and the overall quality of your SEO strategy.

The Quick Answer: No, But They Are Related, Explained!
Domain Authority, often shortened to DA, is a score created by Moz1. It’s designed to predict how likely a website is to rank in search results compared with other websites. It does this by looking at backlink-related signals and turning them into a score. Moz is clear that Domain Authority is not a Google ranking factor and does not directly affect search results2.
Domain Trust is usually used to describe backlink trust or backlink quality. In many SEO conversations, this is closely linked to Majestic’s Trust Flow metric3, which scores the quality of backlinks to websites and URLs. Majestic explains that Trust Flow focuses on backlink quality4, while Citation Flow reflects the quantity of links pointing to a website.
So, while both metrics can help you assess a website’s backlink profile, they are looking at it from different angles.
Domain Authority is more about predicted ranking strength.
Domain Trust, or Trust Flow, focuses on the quality and credibility of the links pointing to a site.
It's not a score from Google. It's not a direct ranking factor. It's not a guarantee that your website will rank well.
What is Domain Authority?
Domain Authority is a metric originally created by Moz to estimate how likely a website is to perform in search compared with others.
It’s usually shown as a score from 1 to 100. In general, websites with stronger backlink profiles are likely to have higher DA scores. This can make it useful when comparing websites, reviewing competitors, or assessing whether a site appears to have built up authority over time.
The important part is understanding what DA is not.
It’s not a score from Google. It’s not a direct ranking factor. It’s not a guarantee that your website will rank well.
Moz is clear on this point, explaining that “Domain Authority is not a Google ranking factor and has no effect on the SERPs.”2 That distinction matters because it stops businesses treating DA as something Google is directly measuring. Instead, it should be used as a helpful benchmark when comparing websites, reviewing competitors, or assessing backlink strength over time.
A website with a higher DA can still struggle to rank if its content is poor, its technical SEO is weak, or the page does not properly answer what users are searching for. Likewise, a lower DA website can still perform well for specific, relevant searches if the content is strong and the site is well optimised.
The best way to think about Domain Authority is as a useful indicator, not a final judgement.
It can give you a sense of perceived SEO strength, but it should never be the only thing you focus on.
What Is Domain Trust?
Domain Trust is a broader phrase often used to describe how trustworthy a website’s backlink profile appears.
In practical SEO conversations, this is commonly linked to Majestic’s Trust Flow. Trust Flow looks at the quality of backlinks pointing to a website or URL. The idea is simple: a link from a respected, relevant, high-quality website is more valuable than a large number of weak, irrelevant, or spammy links.
Majestic describes Trust Flow as a metric that “represents the quality of backlinks to URLs and websites.”3 In simple terms, this means Trust Flow is less concerned with how many backlinks you have and more concerned with whether those links come from credible, trustworthy sources.
This is where many businesses misunderstand backlinks.
It is easy to assume that more links automatically means better SEO. In reality, where those links come from matters far more than the number alone.
A backlink from a trusted industry publication, a respected local organisation, or a relevant business/partnership can carry far more value than dozens of links from low-quality directories or spam-heavy websites.
That is why trust-based link metrics can be useful. They encourage you to look beyond volume and think about the credibility of your website’s connections.
The Key Difference: Strength vs Trust
The clearest way to understand the difference is this:
- Domain Authority is about predicted strength.
- Domain Trust is about backlink credibility.
Domain Authority gives you an estimate of how strong your website might appear from an SEO perspective. Domain Trust gives you a sense of whether the sites linking to you are credible and trustworthy.
A simple analogy is to think of Domain Authority like your reputation. It gives people a broad idea of your influence. Domain Trust aka Trust Flow is more like your references. If the people vouching for you are respected, relevant, and credible, your reputation becomes stronger. If the people vouching for you are questionable, your reputation becomes harder to trust.
Both are useful, but they do different jobs.
A score can be useful, but it should not become the strategy.
Why Backlink Quality Matters More Than Quantity
Backlinks are still an important part of SEO, but the quality of those links matters.
A strong backlink profile is not built by collecting as many links as possible. It is built through relevance, credibility, and trust. Links should make sense. They should come from websites that have a genuine reason to reference yours.
Low-quality links are not automatically a disaster, especially because many websites naturally attract the odd strange or irrelevant backlink over time. However, manipulative link building, paid links created to influence rankings, and spam-heavy backlink patterns can create serious problems.
Google’s spam policies state that spam tactics can lead to a page or an entire site being ranked lower or in more extreme cases completely disregarded from Google Search.5 That is why backlink quality matters. Poor-quality links are not always automatically harmful, but manipulative link building can create long-term issues if it’s being used to influence rankings unnaturally.
This is why quality matters.
A smaller number of strong, relevant backlinks will almost always be healthier than a large number of poor-quality links that exist purely to inflate SEO metrics.
What Should Businesses Focus On Instead?
A recurring issue with SEO metrics is that they can become distracting. It’s easy to chase a higher DA score or obsess over Trust Flow without looking at the bigger picture. A score can be useful, but it should not become the strategy.
A healthier approach is to focus on the things that genuinely improve your website over time.
That means creating useful content, keeping your website technically sound, improving user experience, and earning backlinks from credible sources. It also means avoiding shortcuts that promise quick ranking improvements through low-quality or manipulative link building.
If you are reviewing your backlink profile, look at where your links are coming from. Are they relevant? Are they from trustworthy websites? Do they make sense in context? Would that link still be valuable if SEO did not exist?
That last question being a great test.
If a link is only there to manipulate a metric, it probably isn’t helping your long-term SEO.
How This Fits Into Your Wider SEO Strategy
Domain Authority and Domain Trust should sit within a wider SEO conversation, not replace it.
They can be useful when used for competitive research, checking backlink quality, or spotting areas for improvement. They can also help highlight whether your website is building authority over time.
But they should be viewed alongside other important SEO factors, including content quality, technical performance, indexing, page structure, internal linking, local search presence, and user experience.
For example, a site might have a decent Domain Authority score but still fail to convert visitors because the website itself is difficult to use. Another site might have a smaller backlink profile but perform well locally because its content, reviews, and service pages are highly relevant.
SEO works best when all of these pieces support each other.
Conclusion
So in conclusion, Domain Trust and Domain Authority are not the same thing.
Domain Authority is a Moz metric that estimates ranking potential. Domain Trust, often discussed through Majestic’s Trust Flow, focuses more on backlink quality and credibility.
Neither is a direct Google ranking factor, but both can offer useful insight when reviewed properly.
The key is not to obsess over the scores. The real goal should be building a strong, trustworthy website supported by useful content, good technical SEO, and credible backlinks.
