So, what exactly is Domain Authority? Put simply, Domain Authority (DA) is a score from 1 to 100 that predicts how likely your website is to rank on search engine result pages. Think of it as your website's online credibility score—the higher it is, the stronger your ranking potential.
Understanding Domain Authority and Why It Matters
Let's use an analogy. Imagine your website is a new business setting up shop in Kansas City. Domain Authority is like your local reputation or "street cred." A high score tells everyone you're a trustworthy, authoritative source, kind of like a well-respected local institution such as The Kansas City Star. A low score is like being the new kid on the block—you still have a lot to prove.
But here’s a critical point that trips a lot of people up: DA is not a direct Google ranking factor. Google doesn't look at your Moz DA score and decide where to rank you. Instead, DA is a predictive metric developed by Moz to help you size up your site's competitive strength. While Google ignores the score itself, the ingredients that cook up a high DA—things like high-quality backlinks and a strong link profile—are the very things Google does value immensely.
One of the biggest mistakes you can make is treating Domain Authority as the ultimate goal of an SEO campaign. Its real power isn't in the number itself, but in how you use it for competitive analysis. It helps you understand where you stand against others in your industry and what it'll realistically take to start outranking them.
So, what does Domain Authority mean in practical, day-to-day terms? It’s a powerful way to measure your site's overall SEO health and potential. By keeping an eye on it, you can:
- Benchmark Against Competitors: See how your website's authority stacks up against the sites that are currently ranking for your most important keywords. Practical Example: If you're a Kansas City plumber, you can check the DA of the top 3 plumbing sites in local search. If they all have a DA of 35-40, you know your target is to get your DA above 30 to start competing.
- Track SEO Progress Over Time: A rising DA is a fantastic indicator that your efforts to improve website SEO are actually working.
- Spot Link-Building Opportunities: Analyzing the backlink profiles of competitors with high DA scores can uncover a goldmine of valuable opportunities for your own strategy.
In short, it’s a widely recognized metric that gives you a solid estimate of your ranking potential. Most websites land somewhere between a DA of 20 and 40, while massive, authoritative sites like Wikipedia often score above 90.
Domain Authority Score Tiers at a Glance
To give you a better feel for what these numbers mean in the real world, this table breaks down the different DA score ranges.
| DA Score Range | What It Means | Example Website Type |
|---|---|---|
| Below 30 | New or low-authority sites with a small backlink profile. Competition is tough. | A new local business blog or a personal portfolio site. |
| 30 to 50 | Established sites with some authority and a decent link profile. Good ranking potential for less competitive keywords. | A well-known regional company or a popular niche blog. |
| 50 to 70 | Strong authority and a broad, high-quality backlink profile. Can compete for more competitive keywords. | A national e-commerce brand or a reputable industry publication. |
| Above 70 | Elite authority with an extensive and powerful backlink profile. These sites are market leaders. | Global news organizations, major software companies, or household name brands. |
Understanding where your site fits into these tiers is the first step toward building a smarter, more effective SEO strategy.
How Domain Authority Is Actually Calculated
Moz calculates Domain Authority using a machine-learning algorithm that looks at dozens of different signals. But while the exact formula is a closely guarded secret, the entire process really boils down to one core idea: the quality and quantity of websites linking back to yours.
Think of each backlink as a vote of confidence. A single, powerful recommendation from an industry giant like Forbes carries far more weight than a hundred mentions from brand-new, unknown blogs. This concept is often called link equity, where high-authority sites pass more value and trust through their links, directly boosting your score. This is why a strong, healthy backlink profile is the absolute cornerstone of a high DA.
The Key Ingredients of Your DA Score
The algorithm zones in on a few key signals to figure out your score. These are what help Moz get a clear picture of the overall strength and trustworthiness of your website's link profile.
Here’s what really moves the needle:
- Linking Root Domains: This is the number of unique websites linking to you. Getting 50 links from 50 different websites is always more valuable than getting 50 links from just one site.
- Quality of Inbound Links: The algorithm weighs the authority of the sites linking to you. A link from a reputable, established website is worth exponentially more than one from a spammy or irrelevant source.
- Total Number of Backlinks: While quality definitely trumps quantity, the total volume of links you have still plays a role in the final calculation.
This infographic does a great job of simplifying how Domain Authority works as both a predictive and a comparative tool.
It helps visualize DA not just as some arbitrary number, but as a metric that helps you predict ranking potential and see how you stack up against the competition.
The algorithm considers over 40 different factors, but backlinks are by far the most influential piece of the puzzle. For instance, websites with more than 1,000 high-quality backlinks from diverse domains have an average DA of 65, while sites with under 100 backlinks average a DA of just 28.
You can learn more about these factors by exploring Moz’s research on Domain Authority. Understanding the health of your site's links is the first step, which is why it's so important to regularly analyze your what is backlink profile and clean up any low-quality or spammy links you find.
Clearing Up Common Domain Authority Myths
In the world of SEO, few metrics are as misunderstood as Domain Authority. It’s time we set the record straight on a few common myths that can easily send your strategy spinning in the wrong direction.
The single biggest misconception is that Domain Authority is a Google ranking factor. Flat out, it’s not. Google has confirmed many times that it does not use this score in its algorithms. DA is a predictive metric created by Moz to gauge a site's competitive strength, not a number that directly influences your search results. Think of it as a helpful weather forecast, not the weather itself.
High DA Does Not Guarantee Top Rankings
Another common myth is that a high DA score is a golden ticket to the first page. While a strong score is often correlated with good rankings, it’s not a guarantee. A website with a lower DA can absolutely outrank a site with a higher one if its content is more relevant, specific, and better answers what the user is looking for.
For instance, a highly targeted blog post about Kansas City's best coffee shops (DA 25) can easily beat a generic national food blog (DA 60) for that local search because it directly serves the user's intent. This is also where the specificity of what is Page Authority comes into play, as an individual page's strength can often matter more for specific queries.
The most effective way to use Domain Authority is for comparison, not as a standalone goal. Your focus should be on building an authority score that is competitive within your specific industry, not on chasing a perfect 100.
Finally, a lot of people get hung up on chasing an impossibly high DA score, like 80 or 90. In reality, only about 0.5% of all websites ever reach a DA of 90 or higher. You can discover more insights about DA score distribution on Moz.com. A much smarter goal is to analyze your direct competitors and aim to build a score that puts you in their league.
Actionable Strategies to Increase Your Domain Authority
Knowing what Domain Authority is and actually improving it are two very different things. Let’s be clear: increasing your score is a marathon, not a sprint, and it all comes down to one core mission: building an authoritative, high-quality backlink profile.
Think of every quality backlink as a vote of confidence from another corner of the web. The more credible "votes" you collect, the more your site's reputation grows. The best strategies aren't about quick tricks; they're about creating assets that other websites genuinely want to reference.
Master the Art of Earning High-Quality Backlinks
Your entire strategy should revolve around earning links from relevant, trustworthy websites. A single link from a respected industry authority is far more powerful than dozens of links from low-quality, unknown blogs.
Here are the most effective ways to build a powerful link profile:
- Guest Blogging on Relevant Sites: Don't just write for anyone. Target well-respected blogs and publications within your niche. Actionable Insight: A Kansas City marketing agency should be contributing to the KC Chamber of Commerce blog or national marketing sites like Search Engine Journal—not a generic lifestyle website. This gets your brand in front of the right audience and earns a valuable, contextually relevant backlink.
- Create Link-Worthy, Data-Rich Content: Journalists, bloggers, and industry experts love to cite original research, compelling data, and deep-dive case studies. Actionable Insight: A local real estate agent could publish a "State of the Kansas City Housing Market" report with original data. This is highly likely to attract links from local news outlets, financial blogs, and other real estate professionals.
- Leverage Digital PR for Authoritative Mentions: Digital Public Relations is all about getting your brand mentioned on high-authority news sites and online publications. Actionable Insight: A tech startup in KC could issue a press release about a new funding round or innovative product launch, then pitch the story to local outlets like the Kansas City Business Journal or tech publications. These mentions often come with powerful backlinks that can give your DA a significant boost.
Remember, the goal isn't just to get links; it's to earn them. Every piece of content you create should be so valuable that other sites feel compelled to link to it as a resource for their own audience.
These methods show just how closely your DA is tied to the strength of your backlink profile. Over time, DA scores can fluctuate as new links are acquired or lost, and as the web itself evolves. You can discover more insights about link profiles on Moz.com.
To help you decide where to focus your energy, here’s a look at some common tactics and their potential impact.
Actionable Link Building Tactics and Impact Level

| Digital PR & Media Outreach | High | Very High |
| Broken Link Building | Medium | Medium |
| Creating "Ultimate" Guides | Medium to High | High |
| Infographic & Asset Creation | Medium | Medium |
| Directory Submissions (Niche-Specific) | Low | Low |
As you can see, the tactics that require the most effort—like creating original research or landing a mention in the press—are the ones that deliver the biggest rewards.

How to Check and Monitor Your Domain Authority
Tracking your Domain Authority is a piece of cake, but using that data to make smart decisions is what separates the pros from everyone else. Knowing your number is just the first step; the real power comes from seeing where you stand next to your competition.
You can easily check your score with free tools like Moz’s Link Explorer or paid platforms like Ahrefs (Domain Rating) and Semrush (Authority Score). Just plug in your URL, and you'll get your DA along with a ton of useful info about your backlink profile. This is an essential part of any SEO audit and gives you a clear benchmark to work from.
Using DA for Competitive Analysis
Honestly, the most practical way to use your DA score is to size up the competition. Don't just obsess over your own number. Instead, check the DA of the websites that are already on page one for your target keywords. This immediately shows you the "authority gap" you need to close.
Your goal isn't to chase a perfect score of 100. It's to understand the authority level required to compete in your specific niche and then build a strategy to meet or exceed that benchmark.
By keeping an eye on both your DA and your competitors' scores, you can spot trends over months, not days. Don't sweat the small fluctuations—they're totally normal. What you're looking for is a steady upward trend, which is a great sign that your link-building efforts are paying off. This helps you make smarter, data-driven moves for your site's growth. To get the full picture, it's also a good idea to learn how to check backlinks in Google, since that gives you deeper insight into what's actually driving your score.
Your Domain Authority Questions Answered
Even with the best planning, practical questions always pop up when you start digging into Domain Authority. It's completely normal. Let's tackle some of the most common ones I hear from clients.
How Long Does It Take to Improve Domain Authority?
Improving your Domain Authority is a marathon, not a sprint. This isn’t something you can fix in a weekend. Since the score is so heavily tied to earning quality links from other reputable sites, progress is slow and steady.
You might see some small, encouraging movements in 3-6 months, but significant, lasting improvements typically take a year or more of consistent, high-quality SEO and content marketing. Patience is the name of the game here.
What Is a Good Domain Authority Score?
This is the million-dollar question, but the honest answer is: a "good" score is completely relative to your direct competition. Chasing an arbitrary number like 50 is a waste of time. Instead, your real job is to analyze the DA scores of the websites already ranking on the first page for your most important keywords. Your goal is to get in their league.
A much better approach is to focus on closing the gap with your key competitors. If they have a DA of 40, your initial goal should be to reach that same level, not to hit a perfect score.
For a brand new site, just getting to a DA of 15-20 is a fantastic starting point and a sign you're on the right track. An established local business here in Kansas City, on the other hand, might need to aim for a DA of 30-45 to be truly competitive in local search results.
Can My Domain Authority Score Go Down?
Yes, your DA score can and absolutely will fluctuate. A decrease can happen for a few reasons: you might lose some valuable backlinks, other high-authority sites could be growing much faster than yours, or Moz might update its calculation algorithm.
Small dips are perfectly normal and not a cause for panic. However, a significant drop should trigger an immediate review of your backlink profile to see if you've lost any key, high-authority links. This kind of proactive monitoring means you can tackle issues before they start to impact your site's perceived strength.
