If you spend any time reading about SEO, you will quickly meet a number: Domain Authority, usually shortened to DA. Guest post sellers quote it, link builders chase it, and beginners worry about it. Yet many people checking their DA could not explain what the number actually measures or where it comes from. That gap leads to bad decisions, like paying for links purely to move a score, or panicking because a competitor’s number is higher.
This guide explains Domain Authority in plain language, shows you how to check any website’s score with a free DA checker, and, most importantly, explains how to interpret the result sensibly for your niche instead of treating it as a verdict on your website.
What Is Domain Authority, Really?
Domain Authority is a score developed by Moz, the SEO software company. It runs from 1 to 100 and predicts, on a relative scale, how likely a website is to rank in search results compared with other sites. It is calculated mainly from the site’s backlink profile: how many sites link to it, how strong and relevant those linking sites are, and how those links are distributed across its pages.
Why the Scale Is Logarithmic
The most misunderstood part of DA is that the scale is logarithmic, not linear. Moving from 10 to 20 is relatively achievable with steady, decent links. Moving from 50 to 60 is far harder, and moving from 80 to 90 is something only the biggest sites on the internet manage. This is why comparing a small local business at DA 25 with a global news outlet at DA 90 is meaningless. They are not playing the same game.
Where the Score Comes From
Moz maintains its own index of the web’s links, and the score is modelled from that data. Because it is a model, DA can shift when Moz updates its index or its calculation, even if your site has not changed at all. A small drop after an update does not automatically mean you lost links or did something wrong. You can read the source explanation in Moz’s own guide to what Domain Authority means, which is worth bookmarking.
How to Check DA With a Free Checker: Step by Step
- Choose a reputable free checker. The most direct route is Moz’s own tool, which you can open through Moz Link Explorer for checking authority and backlinks with a free account that allows a limited number of lookups.
- Enter the root domain. Type the main domain, for example yoursite.com, without a specific page path, unless you specifically want the authority of one page, which Moz reports separately as Page Authority.
- Run the check and note the score. Record the DA, the number of linking root domains, and the date. The linking domains figure often tells you more than the headline score.
- Check two or three real competitors. Look up the sites you actually compete with in search results for your main topics, not famous brands in your wider industry.
- Save the results together. A small table with your score next to your true competitors’ scores is the only comparison that produces useful decisions.
Checking Several Sites Without Paying
Free Moz accounts limit how many queries you can run in a month, and third-party DA checker websites exist that show a Moz-based score without an account. Use those for quick, casual checks, but be careful: some bulk checker sites are cluttered, slow, or unreliable, and a few exist mainly to harvest the domains people enter. Stick to well-known tools, avoid entering anything sensitive, and never pay a random checker site for a metric that Moz publishes itself.
How to Interpret a DA Score in Your Niche
A DA number means nothing on its own. It only becomes useful as a comparison inside a specific competitive set.
Typical Ranges You Will See
- New sites: usually start at the very bottom of the scale and climb slowly as they earn their first genuine links.
- Small local businesses and young blogs: commonly sit in the low-to-mid range, which is completely normal and does not prevent them ranking for local and long-tail searches.
- Established niche sites: a solid mid-range score with links from relevant industry sites is a healthy sign.
- Large publishers and major brands: occupy the top of the scale thanks to years of links from across the web.
A Better Question Than “What Is My DA?”
Ask instead: how do I compare with the five sites ranking above me for the searches I care about, and what links do they have that I could realistically earn too? That question turns a vanity number into a work list. If your competitors are within reach, steady content and outreach will close the gap. If they are enormous national brands, the smarter move is targeting more specific searches where smaller, focused sites win.

DA vs DR vs Real Traffic
Domain Authority is not the only authority score you will meet, and confusing them causes endless muddle in SEO discussions.
Domain Rating From Ahrefs
DR, or Domain Rating, is Ahrefs’ equivalent metric, also scored from 0 to 100 and also based mainly on backlinks. The idea is similar, but the data and calculation differ, so the same site will usually have a different DA and DR. Neither is more “true” than the other. They are two companies’ models built from two different link indexes.
What Neither Score Measures
Neither DA nor DR measures your traffic, your revenue, or the quality of your content. A site can have a modest DA and receive thousands of well-targeted visitors a day from specific searches, while another site with a higher score gets traffic that never converts. Always look at real visitor data in your analytics alongside any authority score before judging how a site is actually performing.
Common Misconceptions and Mistakes to Avoid
- “DA is a Google ranking factor.” It is not. Google has its own internal systems and does not use Moz’s score. DA predicts ranking ability, it does not cause it.
- “I need DA 50 before I can rank.” Small sites rank every day for specific, less competitive searches. Relevance and content quality regularly beat raw authority at the level of an individual page.
- “Buying cheap links will raise my DA safely.” Artificial link schemes can inflate a score temporarily while putting the site at real risk, and the links usually come from sites no genuine business would want to be associated with.
- “My DA dropped, so I was penalised.” Scores move when the provider updates its index or model. Check your actual traffic and rankings before assuming the worst.
- “Higher DA always means a better site to get a link from.” Relevance matters enormously. A modest-score site in your exact niche is usually a more valuable link than a high-score site about something unrelated.
How to Raise Your DA the Honest Way
Earn Links With Content Worth Linking To
Original research, genuinely useful guides, free tools, and clear data roundups are the content types other sites naturally reference. It is slower than buying links, and it is also the only approach that keeps working.
Fix the Links You Are Losing
Check for broken pages on your own site that other websites link to, and redirect them to a live, relevant page. Recovering links you already earned is often the fastest legitimate improvement available.
Be Patient and Consistent
Because the scale is logarithmic and based on accumulated trust, DA grows gradually over months, not days. A steady climb of a few points over a quarter, alongside growing traffic, is a healthy pattern for a real site.
Conclusion
Checking your Domain Authority with a free checker takes two minutes: enter your root domain in Moz’s tool, note the score and linking domains, and repeat for your true competitors. The skill is not in getting the number, it is in interpreting it. Remember that DA is a Moz prediction on a logarithmic scale, not a Google ranking factor, not a traffic measure, and not a target worth chasing for its own sake. Use it as a rough compass for comparing sites in your niche, focus on earning relevant links and publishing useful content, and let the score follow your real progress instead of leading it.
Frequently Asked Questions
What is a good Domain Authority score?
There is no universal good score, because it depends entirely on your competitors. A score is good if it is competitive with the sites ranking for the searches you target. Judge your number against your niche, not against famous websites.
Is Domain Authority a Google ranking factor?
No. DA was created by Moz as a predictive score based on link data. Google does not use it in its ranking systems, although sites with strong link profiles often perform well in both Google’s results and Moz’s model.
How often does Domain Authority change?
It can change whenever Moz updates its link index or scoring model, and whenever your own link profile changes. Small movements up or down are normal, so check monthly rather than daily to see the real trend.
Why is my DA different from my DR?
DA comes from Moz and DR comes from Ahrefs. Each company crawls the web and models authority differently, so different scores for the same site are expected. Use one consistently when tracking your own progress.
Can I check the DA of a site I do not own?
Yes. Authority checkers work on any public domain, which is exactly why the metric is popular for evaluating competitors and potential link partners. You only need ownership verification for tools that show private data, such as Search Console.
