If you're serious about boosting your website's authority, you need a three-pronged approach: earn high-quality backlinks from a diverse set of websites, create killer content that people actually want to cite, and make sure your site is technically flawless. While Domain Authority is a predictive score and not a direct Google ranking factor, the SEO practices that improve it are exactly what you need to do to climb the search rankings.
What Is Domain Authority and Why Does It Matter

Before we get into the nitty-gritty, let's clear up what Domain Authority (DA) actually is. Think of it less like a report card from Google and more like a competitive analysis tool. Developed by the team at Moz, DA is a score from 1 to 100 that predicts how well a website will rank on search engine results pages (SERPs). The higher the score, the stronger its ranking potential.
Here’s where people get tripped up: Google does not use DA as a direct ranking factor. It's a common myth. Instead, DA is a reflection of the signals that do matter to Google, especially a website's backlink profile. A healthy DA score is simply the natural result of solid, all-around SEO—the kind that builds real trust with both people and search engines.
How Moz Calculates Domain Authority
Understanding how the sausage is made helps you focus your efforts where they'll have the biggest impact. Moz’s algorithm uses machine learning to compare your site against the millions of others in its index, predicting your ranking ability based on a few core signals.
The undisputed heavyweight champion here is your backlink profile. The algorithm looks at both the sheer number and the quality of external links pointing to your site. But it's smarter than just a numbers game; it heavily favors link diversity.
The number of unique linking root domains—meaning, how many different websites link to you—is a primary input.
For instance, getting 100 backlinks from 100 different domains is far more powerful than getting 100 links from the same single domain. The first scenario gives you 100 linking root domains, while the second only gives you one. The algorithm also considers factors like the Spam Score of linking sites. A site with a diverse, authoritative backlink profile and a low spam score will almost always have a higher DA. You can dig deeper into how this all works over on MonsterInsights.com.
Key Takeaway: It’s better to get one link each from 10 different high-quality websites than to get 10 links from a single website. Diversity is a powerful signal of credibility.
To really nail down where to focus, it helps to see the key factors in one place. I've put together this table to summarize what truly moves the needle for your Domain Authority score.
Key Factors Influencing Your Domain Authority Score
Here's a quick rundown of the primary elements that contribute to your website's DA score. Use this to help prioritize your SEO efforts.
Influencing Factor | Why It Matters for DA | Quick Tip |
Unique Linking Root Domains | This is the most critical factor. More unique sites linking to you signals widespread credibility and trust. | Focus on acquiring links from a variety of relevant, reputable websites, not just accumulating many links from a few sources. |
Quality of Backlinks | Links from high-authority, trusted websites (like .edu or .gov sites) carry significantly more weight. | Prioritize outreach to established, authoritative sites in your niche. One link from a top-tier site is worth dozens from low-quality ones. |
Content Quality & Value | Great content is "linkable." It naturally attracts links because it's useful, original, and shareable. | Create comprehensive, data-driven, or unique content that other sites will want to reference and link to as a resource. |
Technical SEO Health | A site that is easy for search engines to crawl and index is seen as more reliable. This includes site speed, mobile-friendliness, and a clean site structure. | Regularly run a technical SEO audit. Fix broken links, optimize images, and ensure your site has a clear, logical navigation. |
Spam Score | Moz assesses the "spamminess" of your backlink profile. A high score can hurt your DA. | Periodically review your backlink profile and use Google's Disavow Tool to distance your site from toxic or spammy links. |
Understanding these components is the first step. The real work is in consistently executing the strategies that improve them over time, which will naturally lead to a healthier DA.
Setting Realistic DA Goals
It’s easy to get discouraged when you see giants like Wikipedia (DA 98) or Google (DA 99). But you’re not trying to beat them. A "good" DA score is completely relative to your direct competition.
First, check the DA scores of the sites that are currently ranking on the first page for your most important keywords. If they're mostly in the 30-40 range, setting a goal to reach 45 is both ambitious and achievable. That's your target.
Every new website starts with a DA of 1. Building it is a marathon, not a sprint. It requires patience and consistent effort, so don't expect to see huge jumps overnight. Focus on the small, steady wins that come from doing SEO the right way.
In the end, think of your DA score as a vital sign for your website's health. A rising score is a great indicator that your overall SEO strategy is on the right track. It means you are probably:
- Acquiring valuable backlinks from authoritative sources.
- Creating content that resonates with your audience and earns links.
- Maintaining a technically sound website that search engines can easily crawl and understand.
Chasing a higher DA score just for the number itself is missing the point. The real win is putting in the work that causes the score to rise naturally. That's what leads to better search rankings, more organic traffic, and a stronger online presence.
Creating Content That Earns Authority
High-quality backlinks are the fuel for increasing your domain authority, and let's be honest, exceptional content is what gets other sites to link to you. But vague advice like "write great content" is just frustrating. What you really need is a practical playbook for creating assets that naturally pull in authoritative links.
The secret isn't just about writing longer articles. It's about creating content that serves a very specific purpose for other creators, journalists, and industry experts. I like to think of it as building "linkable assets"—pieces so valuable they become the go-to resource on a topic. This is how you start earning backlinks, not just asking for them.
Go Beyond Standard Blog Posts
A standard blog post, while valuable for your audience, often isn't enough to attract links from high-authority domains. To earn those powerful links, you have to level up your content strategy. The goal is to become a source of truth in your niche.
Here are a few proven content types that are absolute link magnets:
- Original Research & Data Studies: Publishing unique data is one of the most effective ways to earn high-quality links. Journalists and bloggers are always hunting for stats to back up their arguments. When you're the primary source for that data, they have to link to you. A marketing agency, for example, could survey 500 small businesses about their social media habits and publish the findings.
- Definitive Guides: Your mission here is to create the single most comprehensive resource on a topic. If someone is writing about "ketogenic diets," and your guide is the most detailed, well-researched article out there, you've given them a compelling reason to cite you as a trusted source.
- Free Tools & Calculators: Developing a simple, useful tool can generate a steady stream of links for years. A real estate firm could create a mortgage affordability calculator, or a fitness blog could offer a calorie intake calculator. These assets provide ongoing value, making them incredibly linkable.
Adopt the Skyscraper Technique
The Skyscraper Technique, made famous by Brian Dean of Backlinko, is a brilliant way to create content that’s practically engineered to earn links. It's a three-part process that focuses on improving what already works.
First, you find a piece of content in your niche that has already earned a ton of backlinks. Use an SEO tool to find articles on your topic with a high number of referring domains.
Next, it's your job to create something that's not just a little better, but significantly better. This could mean making it more up-to-date with recent statistics, adding more detailed visuals and graphics, improving the design and user experience, or providing more in-depth explanations.
Finally, you reach out to the websites that linked to the original, now-inferior piece. You simply let them know you've created a more comprehensive and updated resource they might be interested in.
Pro Tip: When you're improving content, don't just add more words. Add more value. This could be through expert interviews, custom infographics, or even a downloadable checklist that makes the information more actionable for the reader.
To truly earn authority, your content needs to be part of a bigger plan. Learn more about developing a comprehensive content marketing strategy that aligns with your SEO goals. This strategic approach ensures your efforts are focused and much more effective.
Topic Research for Linkability
Creating linkable assets all starts with smart topic research. You need to find that sweet spot where what your audience is searching for overlaps with what authoritative sites are already linking to. This isn't just about keyword volume; it's about spotting "link gaps."
Look for topics where the existing content is outdated, thin, or just plain shallow. These are prime opportunities to build your skyscraper.
By consistently publishing content that is measurably better than the competition, you build a reputation as a reliable authority. For a deeper dive into building a successful content plan, explore our guide on content marketing best practices. This approach shifts your focus from just writing articles to building a library of assets that work to increase your domain authority around the clock.
Building a Powerful Backlink Profile
If your content is the foundation, then your backlink profile is the steel frame that gives your website real strength and authority. This is where you’ll see the biggest jumps in your Domain Authority. Think of backlinks as votes of confidence from other websites, signaling to search engines that your content is credible and worth paying attention to.
But let’s be clear: not all backlinks are created equal. We're not talking about spammy tactics or buying links. The real art is earning high-quality links from a diverse set of relevant, authoritative sites. That's how you build a profile that genuinely moves the needle.
It’s All About Unique Referring Domains
It’s easy to get hung up on the total number of backlinks. The metric that truly matters, however, is the number of unique referring domains—in other words, how many different websites link back to you.
Why? Because a single link from 100 separate, relevant sites is infinitely more powerful than 100 links from the same site. This diversity tells search engines that your authority is widespread and trusted across the web.
The data doesn't lie. There's a direct, undeniable correlation between a high number of unique referring domains and a high DA score. For instance, sites like Linode (DA 86) and Netlify (DA 88) have backlink profiles with around 23,000 to 25,000 unique referring domains. To hit an even higher score, like Digital Ocean's DA of 91, you're looking at a network of over 86,000 unique domains.
What's more, a critical detail is that roughly 77% of these influential links are "do-follow," meaning they pass SEO equity directly to your site. This is a long-term game, but it's one you can win with the right strategy.

Actionable Strategies for Earning Quality Links
So, how do you actually attract links from thousands of unique domains? It’s not about sitting back and hoping for the best. Building a powerful backlink profile requires proactive outreach and a commitment to creating value for others.
Here are a few proven methods that I've seen work time and time again:
- Targeted Outreach: This isn't about blasting out generic emails. It's about carefully identifying specific websites, journalists, or creators who would find your content genuinely useful. A great outreach email is personalized, clearly explains the value you’re offering, and shows you’ve actually paid attention to their work.
- Guest Posting on Relevant Sites: Writing for other authoritative blogs in your niche is a classic for a reason. It gets your expertise in front of a brand-new audience and earns you a valuable backlink in the process. The key here is to aim for quality over quantity. One guest post on a top-tier industry blog is worth far more than ten on low-quality sites.
- Broken Link Building: This is a fantastic, win-win strategy. The process is simple: find a broken link (one that leads to a 404 error) on another website and then pitch your own relevant content as a replacement. You’re helping the site owner fix an error on their page while earning a link for yourself.
Expert Insight: The secret sauce to all of this is building genuine relationships. Connect with other creators and journalists on social media. Share their work and offer value with no strings attached. Over time, these connections naturally lead to organic link opportunities.
The flow is simple: strong on-page SEO creates the kind of link-worthy assets you need to succeed with your outreach efforts.

This visual really drives home the point that a strong backlink profile starts with having something valuable to link to—a process that is rooted in solid on-page SEO.
A Real-World Outreach Example
Let’s make this more concrete. Imagine you just published the definitive guide on "sustainable gardening for urban spaces." Through your research, you find a popular lifestyle blog with an older article, "10 Tips for Apartment Gardening," but you notice one of their resource links is broken.
Here’s what your personalized outreach email could look like:
Subject: A broken link on your apartment gardening post
Hi [Blogger's Name],
I'm a big fan of your blog—especially loved your recent post on DIY planters!
I was just re-reading your article on apartment gardening and noticed that the link to the "herb growing chart" seems to be broken. It's leading to a 404 page.
We actually just published a comprehensive guide to urban sustainable gardening that includes its own downloadable herb chart. It might be a great replacement resource for your readers.
No pressure at all, but I thought it might be helpful!
Best,
[Your Name]
This email works because it’s personal, helpful, and direct. You’re not just asking for a favor; you’re providing a solution. This approach will dramatically increase your chances of getting a reply and, more importantly, a high-quality backlink.
Strengthening Your Technical SEO Foundation

You wouldn't build a skyscraper on a shaky foundation, and the same principle holds true for your website. While killer content and high-quality backlinks are absolutely essential, their impact is limited if your site's technical health is holding you back. Think of it this way: a technically sound website is one that search engines like Google can crawl, understand, and ultimately, trust.
This trust is a huge piece of the authority puzzle. When search engine bots can move through your site efficiently—without hitting dead ends or getting stuck on slow-loading pages—they see your domain as more reliable. This reliability is a powerful, if indirect, signal that helps increase domain authority over time.
Make Your Site a Joy for Users and Bots
A great user experience (UX) isn't just a "nice-to-have" anymore; it's a core component of modern SEO. Search engines are laser-focused on sending their users to sites that are fast, secure, and easy to navigate on any device. When people have a good experience, they stick around longer, engage more, and are more likely to share your stuff—all positive signals that build authority.
Three technical pillars are the bedrock of a good user experience:
- Mobile-Friendliness: Google runs on a mobile-first indexing model. This means it primarily looks at the mobile version of your site for indexing and ranking. If your site is a pain to use on a smartphone, you're going to have a hard time gaining any traction.
- Site Speed: Page load time is a confirmed ranking factor, period. One study found that the first five seconds of page-load time have the biggest impact on conversion rates. Slow pages cause people to bounce, and search engines definitely take notice.
- HTTPS Security: Using HTTPS (which you get with an SSL certificate) encrypts the data flying between a user's browser and your server. It's now a standard security protocol that builds trust and acts as a lightweight ranking signal.
These aren't just boxes to tick. They are fundamental to creating a website that both people and search engines will love. For anyone just starting out, getting this technical base right from day one is non-negotiable. If you're launching a new website, our comprehensive SEO checklist for new websites is a fantastic resource for getting these fundamentals locked in from the get-go.
The Power of a Clean Site Structure
Beyond speed and security, the way your site is organized has a massive effect on its ability to build authority. A logical, clean site structure helps search engines understand the relationships between your pages and figure out which content is most important.
Imagine your site is a pyramid. Your homepage sits at the very top, with main categories below it, and individual blog posts or pages forming the base. This hierarchy should be clearly reflected in your URL structure and, crucially, your internal linking. A smart internal linking strategy does more than help users find their way around; it also spreads "link equity" (or "link juice") throughout your site.
Key Insight: When you land a powerful backlink to one of your pages, internal links from that page can pass some of that hard-earned authority to other relevant pages on your site. This helps lift the authority of your entire domain, not just a single page.
Conduct a Basic Technical Audit
You don't need to be a developer to spot and fix common technical problems that might be dragging down your DA. Running a basic technical audit is a smart, proactive way to keep your foundation solid.
A great place to start is Google Search Console (it's free!). Pay close attention to the "Coverage" report, which flags any crawl errors that are stopping Google from indexing your pages. You should also regularly check for broken internal links. These create a frustrating user experience and waste valuable link equity. Fixing a broken internal link is a quick win that immediately boosts your site’s health and helps you increase domain authority.
Choosing a Domain and Building Your Brand
Your domain name is so much more than a web address. It’s the cornerstone of your brand and your first real step toward building authority that lasts.
I remember a time when SEOs would cram keywords into their domains, thinking it was a clever shortcut. While that might have given a tiny boost years ago, that game is long over. Today, a strong, memorable, and brandable domain is infinitely more valuable.
Put yourself in a user's shoes. What sounds more trustworthy and easier to recall:
Best-Cheap-Laptops-Online.com
or something like TechTonic.com
? The second one feels like a real brand, a place you'd actually trust and come back to.That brand recognition is precisely what helps you increase domain authority. It builds the kind of trust that inspires other high-quality sites to link to you. A solid, brandable domain helps you stand out and build credibility from the get-go.
The Power of a Strong Digital Identity
Think of your domain as the foundation of your entire online identity. It's what people will type into their browsers, share with friends, and see in search results. A great domain name is:
- Memorable: It should be easy for someone to remember and type without errors.
- Concise: Shorter is almost always better. It’s less prone to typos and easier to share.
- Brandable: It sounds like a real business, not just a jumble of keywords. It’s unique and can grow with you.
Building a brand that people know and respect is a powerful, if indirect, way to fuel your link-building efforts. When a journalist or blogger is looking for a source, they're far more likely to link to a domain that sounds like a legitimate expert in the field.
Adapting to Industry Trends
The world of domains is constantly shifting, often influenced by new tech and industry trends. Just look at the explosion in AI and automation—it has created a massive demand for AI-related domain names.
The global domain market reflects this kind of growth. There are roughly 378.6 million registered domain names worldwide, and that number is expected to hit about 459.9 million by 2030. Industries like machine learning and data analytics are especially aggressive in snapping up strong digital identities. As this market gets more crowded, sites with high-quality, relevant domains are in a much better position to boost their authority. You can dig deeper into the projected growth of the domain name industry on GlobeNewswire.
Ultimately, the goal is to build a brand so recognizable and trusted that it naturally attracts backlinks. That whole process starts with picking a domain that reflects the authority you want to build. It’s a strategic move that will pay off for years, making it one of the most fundamental steps you can take to increase domain authority for the long haul.
Tracking Your DA Growth and Staying Consistent

Let's be real: putting in the work to increase domain authority is a long-term commitment. Think of it as a marathon, not a sprint. Consistency is going to beat short, intense bursts of effort every single time.
You won't see your score jump ten points overnight. In my experience, real progress is gradual and often takes months to become obvious. Setting those realistic expectations from the start is what will keep you from getting discouraged.
So, please, don't obsessively check your DA score every day. Instead, pencil in a monthly review. This gives the algorithms time to actually process the changes you’ve made and will give you a much more accurate picture of your progress.
Tools and Metrics for Monitoring Progress
To know if you’re actually moving the needle, you need the right tools and a clear idea of what to measure. Your DA score? That's just one part of the story. You need a more holistic view to understand your site's true health.
Here are the key platforms I rely on:
- Moz Link Explorer: This is the original source for the DA metric, so it's a must-have. I use it to monitor my score, dig into new backlinks, and keep an eye on my Spam Score.
- Ahrefs: This is my go-to for a really deep dive into a backlink profile. It's fantastic for tracking referring domains and, frankly, for snooping on what competitors are doing to earn their links.
Beyond just the DA number, I'm always laser-focused on these leading indicators of authority:
- Organic Traffic Growth: Is your overall organic traffic trending upward? At the end of the day, this is the ultimate sign that your efforts are paying off.
- New Referring Domains: Keep an eye on the number of unique websites linking to you. A steady, consistent increase here is an incredibly powerful signal to Google.
- Keyword Rankings: Watch your positions for your most important target terms. When you see yourself climbing the SERPs for competitive keywords, you know your authority is growing.
By focusing on these metrics, you’ll find it much easier to stay patient and consistent. You’ll have the proof that your hard work is building real, lasting authority.
Got Questions About Domain Authority?
When you're digging into SEO, it's easy to get tangled up in the details, especially with a tricky metric like Domain Authority. Let's tackle some of the most common questions I hear, so you can move forward with a clearer strategy.
How Long Does It Take to See DA Improvements?
This is the big one, and the honest answer is: it’s a long game. Bumping up your Domain Authority isn’t something you can check off the list in a week. It requires patience and consistency.
From what I've seen, you can expect to see real, meaningful changes within six to twelve months of dedicated, high-quality work. That means regularly publishing genuinely useful content and steadily earning backlinks from reputable sites. Every new website starts with a DA of 1, so think of the journey to a competitive score as a marathon, not a sprint.
What's the Difference Between Domain Authority and Page Authority?
It’s a common point of confusion, but they measure two very different things.
- Domain Authority (DA): This predicts the ranking potential of your entire website. It’s a holistic score that reflects the overall strength of your domain and all its pages combined.
- Page Authority (PA): This, on the other hand, predicts the ranking strength of a single, individual page.
Think of it this way: a single blog post on your site could go viral and attract a ton of amazing links. That specific page might develop a very high PA, even if the rest of your site has a more modest DA. Your goal is to raise both, because a rising tide lifts all ships.
My Domain Authority Score Dropped! What Should I Do?
First off, take a breath. Don't panic. A small dip in your DA score can happen for a bunch of reasons, and it doesn't automatically mean you did something wrong. Moz's index is always changing as it crawls millions of sites, so your score is relative to everyone else's.
It could be that a competitor just had a monster month of link building, which shifts the curve for everyone. However, if you see a significant drop, it’s worth a look. The first thing I'd do is run a backlink audit to see if you've picked up any new, spammy links that might be dragging you down. After that, pop into Google Search Console to check for any manual actions or major crawl errors. More often than not, a small dip is just a temporary fluctuation, but it's always a good reminder to keep your SEO house in order.
