What Is Domain Authority in SEO and How to Boost Your Score

Domain Authority (DA) is a score created by Moz that predicts how likely a website is to rank in search engine results. It’s essentially a credibility score for your entire website, measured on a scale from one to 100. The higher your score, the better your chances are of ranking for the keywords you’re targeting.

What Is Domain Authority in SEO

Think of your website as being in a huge online popularity contest. In this contest, not every vote has the same value. A nod from a highly respected source, like a major industry publication, means a whole lot more than one from a brand-new blog. Domain Authority is the metric that tries to put a number on this kind of influence.

It’s important to know that DA isn’t a ranking factor Google uses directly. Instead, it’s a comparative tool-a way for you to see how your site’s authority stacks up against your competitors. A high DA often goes hand-in-hand with strong rankings, which is why it’s a key performance indicator for any serious SEO strategy. It gives you a clear picture of where you are, helps you benchmark progress, and lets you set achievable goals for your content and link-building work.

To give you a clearer picture, here’s a quick breakdown of what makes up Domain Authority.

Domain Authority at a Glance

Ultimately, Domain Authority gives you a single, easy-to-understand number that reflects the strength of your website’s overall SEO foundation.

The Origins of Domain Authority

To really get why DA is so important, it helps to know what came before it. For a long time, the SEO world revolved around Google’s PageRank, a 0-10 score that showed how important a page was based on its backlinks. But after 2013, Google stopped updating PageRank publicly, leaving a huge hole. SEOs and marketers were suddenly without a reliable yardstick to measure a site’s authority.

Moz saw the need and stepped in, introducing Domain Authority around 2009. Their metric was designed to fill that void. It analyzed over 40 different signals-with the quality and quantity of backlinks being the most important-to generate its predictive 1-100 score. It wasn’t long before DA became the go-to metric for gauging a site’s ranking potential. If you want to dive deeper into the history, WebsiteSEOChecker has a great overview.

In essence, Domain Authority was created to provide a directional metric for SEOs after Google’s own public-facing score disappeared. It offers a consistent way to track how your site’s authority grows over time.

Why It Matters for Your Business

So, what does this all mean for your business? In simple terms, Domain Authority is your competitive barometer.

Knowing your DA and the scores of your competitors tells you exactly how much work is ahead of you. Let’s say your SaaS has a DA of 30 and your biggest competitor is sitting at a 65. That gap tells you that you have a steep climb ahead in building a backlink profile that can compete.

Understanding your DA helps you:

• Assess competitive strength: Get a quick, at-a-glance idea of how you measure up against others in your space.
• Guide link-building efforts: Focus your energy on earning backlinks from sites with higher DA scores, because those “votes” carry much more weight.
• Measure SEO progress: Track your DA score over the months and years as a tangible sign that your authority-building campaigns are actually working.

How Domain Authority Is Really Calculated

If you want to get what Domain Authority is all about, you have to pop the hood and see how it works. While Moz keeps the exact formula under lock and key, they’re very clear about one thing: it all comes down to the quality and quantity of backlinks pointing to your site. Think of every backlink as a vote of confidence from another website.

But here’s the thing-not all votes are equal. The engine that powers DA is smart enough to look at your entire backlink profile, not just a raw count of links. This is where a concept called linking root domains becomes the most important factor for anyone serious about SEO.

Linking Root Domains: The Real Powerhouse

A “linking root domain” is just a fancy way of saying a unique website that links to you. Getting ten links from ten different well-regarded sites is way more powerful than getting ten links from the same site. Why? Because it tells search engines that your content is trusted by a wide variety of sources, not just one super-fan.

It’s like running for office. What looks better? One enthusiastic endorsement from a single community leader, repeated ten times? Or ten separate endorsements from ten different respected leaders? The second option shows broad support and credibility, and that’s exactly how it works for your website.

This concept map helps visualize how Domain Authority acts as a credibility score, directly impacting your potential to rank and get a leg up on the competition.

As the map shows, DA isn’t just a number; it’s a reflection of your site’s ability to stand out and earn trust.

Backlinks are the undeniable engine here. The algorithm counts your total number of links but gives far more weight to your linking root domains. And quality is everything. A single, powerful link from a DA 80 site like TechCrunch can easily be worth more than dozens of links from smaller DA 20 blogs.

In fact, data from Moz suggests that sites with over 100 high-quality root domains tend to hit a DA of 45 or more. On the flip side, sites with fewer than 20 often get stuck in the 15-25 range.

Understanding The Logarithmic Scale

Another critical piece of the puzzle is that Domain Authority is measured on a logarithmic scale. That might sound a bit nerdy, but it’s a simple idea that’s essential for setting realistic goals.

Basically, it’s much easier to grow your DA score when it’s low than when it’s high.

• Easier Growth (Lower DA): Going from a DA of 20 to 30 is a tough but achievable goal for a new site putting in the work.
• Harder Growth (Higher DA): Climbing from a DA of 70 to 80 is a massive undertaking that requires earning links from the internet’s most authoritative websites.

Think of it like a video game. Leveling up from 1 to 10 is fast and feels great. But going from Level 70 to 71? That takes a huge amount of effort for just one level. DA is the same way.

This scale is designed this way for a reason-it reflects how authority actually works on the web. There are millions of sites with low-to-medium authority, but only a handful are truly elite. For a SaaS startup, this means your strategy should be about steady, consistent gains. Focus on leapfrogging your direct competitors first, not trying to take on the industry giants overnight.

How DA Stacks Up Against Other SEO Authority Metrics

Domain Authority doesn’t live on an island. While it’s one of the most well-known scores for estimating a website’s strength, it’s just one of many third-party metrics out there, each with its own secret sauce. Knowing how they differ is crucial if you want to use them for smart competitive analysis.

The biggest comparison you’ll see is between Moz’s Domain Authority (DA) and Ahrefs’ Domain Rating (DR). Both run on a 0 to 100 scale and try to measure the strength of a site’s backlink profile. But-and this is a big but-they are not the same. Their calculation models have some key differences, so you can’t treat them interchangeably.

Think of it like two different credit scoring models, say FICO and VantageScore. Both are trying to predict your creditworthiness, but they weigh various factors differently and can give you slightly different numbers. In the same way, DA and DR offer two unique lenses through which to view your site’s authority.

Moz DA vs. Ahrefs DR: The Key Differences

The main split between DA and DR comes down to how they look at backlinks. Moz’s Domain Authority is a bit more complex, pulling in over 40 different signals. It considers things like the total number of links and the count of unique websites linking to you (linking root domains), but it also tries to factor in more nuanced signals like link quality and spam indicators, aiming to mimic how Google might see your site.

Ahrefs’ Domain Rating, on the other hand, is more direct. It focuses almost entirely on the quantity and quality of backlinks pointing to your entire domain. One of the most significant differences is that DR counts all links, including “nofollow” links, while DA mostly ignores them. This alone can cause a pretty big gap between the two scores for the exact same website.

The most important thing to remember is that neither DA nor DR is a direct ranking factor for Google. They are diagnostic tools built by SEO software companies to help you gauge your progress and size up the competition.

A Quick History Lesson: Google PageRank

To really get why metrics like DA and DR are such a big deal, you have to rewind to Google’s original PageRank. For a long time, PageRank was a public score from 0 to 10 that every SEO obsessed over. It was the original “link juice” metric, telling you how much authority a specific page had.

But in 2013, Google stopped showing PageRank updates to the public, which left a huge void. SEOs and marketers were suddenly flying blind, without a reliable way to measure the authority of their own sites or their competitors’. This is exactly the gap that Moz’s Domain Authority and, later, Ahrefs’ Domain Rating were built to fill. They stepped in to become the new industry standards.

To help you sort out which metric to use for what, here’s a quick breakdown.

DA vs. DR: A Quick Comparison for SaaS Marketers

This table compares Moz’s Domain Authority (DA) and Ahrefs’ Domain Rating (DR) to help you understand their key differences.

At the end of the day, you don’t have to pick a side. Most savvy SaaS marketers keep an eye on both. Think of DA as your high-level indicator for your site’s overall health and authority, and use DR to get a more granular view of your raw backlink power. Knowing what each metric actually measures-and what it doesn’t-is the key to building a much smarter and more effective SEO strategy.

Common Domain Authority Myths You Should Ignore

Chasing the wrong SEO goals is a fast track to wasting time and money. When it comes to Domain Authority, there are a few stubborn myths that constantly send marketers down the wrong rabbit hole. Let’s clear the air and bust these misconceptions so you can focus on what actually works.

Getting this right is critical. Obsessing over a single vanity metric will distract you from the real work of building a great website that earns authority and traffic for the long haul. The goal isn’t just to pump up a number; it’s to build a site people trust.

Myth 1: DA Is a Direct Google Ranking Factor

This is the biggest one, so let’s get it out of the way first. Domain Authority is not a metric used by Google. Full stop. It was created by Moz as a way to predict a site’s ranking potential, but Google’s own algorithm is a completely different, massively complex beast.

Yes, there’s a strong correlation-websites with a high DA tend to rank well. But that’s a classic case of correlation, not causation. A high DA score is the result of being an authoritative, well-regarded site, not the cause of good rankings.

Reality Check: Think of DA as a helpful third-party estimate of your site’s overall strength. It’s great for benchmarking against competitors and tracking your progress over time, but never mistake it for an instruction manual on how to please Google.

Myth 2: A High DA Guarantees Traffic

It’s tempting to believe that a high DA score is a golden ticket to a flood of organic traffic. If only it were that simple. A website with a DA of 70 can absolutely be a ghost town if its content isn’t what people are actually searching for.

At the end of the day, relevance is king. You can have all the “authority” in the world, but if your pages don’t actually answer a searcher’s question, you’re not going to rank or get clicks.

A few things are far more important for driving traffic than DA alone:

• Keyword Targeting: Are you creating content around topics your audience actually cares about?
• Content Quality: Does your content genuinely solve a problem or answer a question better than anyone else?
• User Intent: Does your page deliver what the searcher really wants when they type in their query?

For instance, a super-specific, helpful blog post on a site with a DA of 30 can easily outrank a vague, generic article on a DA 80 corporate site if it perfectly matches what the searcher is looking for.

Myth 3: I Should Only Focus on My DA Score

Fixating on your DA score is like staring at the scoreboard instead of playing the game. Domain Authority is an output metric-it’s a reflection of your SEO efforts, not the effort itself. It should never be the primary goal of your strategy.

Instead of asking, “How do I increase my DA?” you should be asking much better questions:

• How can we earn more high-quality backlinks from relevant, trustworthy sites?
• How can we create content so good that other experts in our field want to link to it?
• How do we make our site’s technical foundation and user experience flawless?

Focus on these pillars of good SEO, and your Domain Authority will rise naturally as a byproduct of doing great work. It’s just one piece of a much larger puzzle, not the whole picture.

Actionable Strategies to Increase Your Domain Authority

Knowing what Domain Authority is gets you to the starting line. Actually improving it is where the real race is won. Bumping up your DA score is a long-term game, and it all comes down to one core activity: earning high-quality backlinks from reputable, relevant websites.

Think of it like building your professional network. Every solid connection you make adds to your credibility and opens new doors.

For a SaaS company, this isn’t about chasing vanity metrics. It’s about building a powerful digital footprint that fuels real, organic growth. The strategies I’m about to share are designed to create a sustainable feedback loop: create genuine value, earn recognition for it, and watch your authority grow as a natural result.

Build a Foundational Link Profile

Every new SaaS tool needs an initial set of credible links to prove it’s the real deal. This is where you can be smart and strategic with directory submissions. Getting your product listed on well-regarded software and startup directories is one of the quickest, most effective ways to build that foundational backlink profile.

These sites are trusted hubs where buyers go for recommendations, so a link from them acts as an instant, relevant vote of confidence. This early push gets your domain on the radar. You can check out a curated list of high-impact SaaS directories to find platforms that fit your niche and start building momentum.

Create Link-Worthy Content Assets

The single most sustainable way to attract top-tier backlinks is to create content that other websites simply have to link to. I’m not just talking about another blog post. I’m talking about developing true “link assets.”

For a SaaS business, this could look like:

• Original Research or Data Studies: Run a survey in your industry and publish the results. Suddenly, you’re the primary source of new information, making your report a magnet for links from journalists and bloggers.
• Free Tools or Calculators: Build something simple that solves a common pain point for your audience. A free ROI calculator or a headline generator can passively earn hundreds of organic links for years.
• Comprehensive Guides or Whitepapers: Aim to create the definitive, go-to resource on a crucial topic in your field. When you have the best guide on the internet, everyone else will cite it.

These assets work like magnets, pulling in backlinks long after you’ve hit the publish button.

The core idea is simple: create something so valuable that linking to it makes other content creators look smarter and more helpful to their own audiences.

Execute Strategic Guest Posting

Guest posting is a fantastic, proactive way to build authority. The concept is straightforward: you write and publish an article on another website within your industry. This gets you in front of an established audience while earning a powerful backlink from an authoritative domain.

The secret here is focusing on quality, not quantity. Don’t just spray and pray. Instead, identify a handful of high-DA blogs that your target customers genuinely read. Pitch them a unique, well-researched article that offers real value to their audience. One link from an industry-leading site is worth more than a dozen from low-quality blogs.

Master Your Technical and On-Page SEO

Think of your website’s technical health as the foundation of a house. All your authority-building efforts are the structure you build on top. If that foundation is cracked-if search engine crawlers can’t easily find, understand, and index your content-your whole strategy will crumble.

A clean technical setup ensures all the “link equity” you work so hard to earn is properly distributed across your site.

Here are the key areas to nail down:

• Site Speed: Your pages have to load fast. It’s a non-negotiable for a good user experience.
• Mobile-Friendliness: Your site must work flawlessly on any device, from a desktop to a smartphone.
• Clean URL Structure: Use simple, descriptive URLs. They’re easier for both people and search engines to understand.
• Internal Linking: Strategically link between related pages on your own site. This helps spread authority and guides your visitors.

It’s crucial to remember that Domain Authority is measured on a logarithmic scale, which means early gains are easier to come by. Moving from DA 10 to 20 might only take 20-30 quality backlinks. But climbing from 50 to 60? That could demand over 200 high-quality links.

This model mirrors how search engines work; globally, only 0.1% of domains ever break a DA of 90. For most SaaS businesses in competitive markets, hitting a DA of 40+ is a massive achievement that often correlates with dominating organic traffic.

How to Track Your Domain Authority Progress Effectively

If you can’t measure it, you can’t prove it. To show the real value of your SEO work, you need a simple way to track your Domain Authority progress and connect it to actual business results. It’s less about obsessing over a single number and more about understanding the story that number tells about your website’s growing influence.

First things first, you need a regular check-in schedule. Using a tool like Moz’s Link Explorer, you can pull your DA score in seconds. For most SaaS teams, a monthly check-in is the sweet spot. DA doesn’t change overnight, so checking it daily or weekly is a recipe for anxiety. A monthly snapshot gives you enough data to see trends without getting bogged down by tiny, meaningless fluctuations.

Connect DA to Metrics That Matter

Your DA score is a signpost, not the destination. The magic happens when you tie its movement to the performance metrics that actually grow your business. Any tracking you do should always connect your DA score back to these three core areas.

• Growth in Linking Root Domains: This is the fuel for your DA score. Are you consistently earning links from new, unique websites? A rising DA should go hand-in-hand with a growing number of referring domains.
• Increased Organic Traffic: As your site’s authority builds, you should naturally see more organic traffic. This is the ultimate confirmation that your growing credibility is actually getting more people to your site from search engines.
• Improved Keyword Rankings: A higher DA gives you a better shot at ranking for those valuable, high-competition keywords. Keep an eye on your positions for key commercial and informational terms to see if your authority gains are helping you climb the search results.

This shifts your reporting from a flat “our score went up” to a powerful narrative: “our authority-building efforts drove more high-quality links, which boosted our traffic by 15% this quarter.” If you’re looking for help shaping your SEO strategy or tracking results, you can reach out to our team at SubmitSaaS for guidance.

The goal is to prove the ROI of your work. By linking your Domain Authority progress to traffic and rankings, you can clearly communicate the business impact of your SEO campaigns to stakeholders.

A Simple Reporting Framework for SaaS Teams

Showing your progress clearly is just as important as making it. Don’t drown stakeholders in complex spreadsheets filled with jargon. Instead, use a simple, visual report that tells a compelling story at a glance.

Your monthly report could feature a straightforward table like this one:

This format is clean, easy to scan, and immediately connects the dots between your authority-building work (DA and links) and the bottom-line results (traffic and rankings). It gives you everything you need to demonstrate value, justify your strategy, and keep the momentum going for your SEO program.

A Few Final Questions About Domain Authority

Alright, let’s wrap this up by tackling some of the most common questions I hear about Domain Authority. Getting these answers straight will help you put this metric to work in the real world.

How Long Does It Take to See an Increase in Domain Authority?

Improving your Domain Authority is a marathon, not a sprint. It’s a long-term game. For a brand-new SaaS website, you might start seeing the needle move within three to six months of dedicated, high-quality link building. But that’s just the beginning.

Your progress is tied directly to the quality of the backlinks you’re earning and how frequently you’re earning them. Because DA is on a logarithmic scale, the early gains are the easiest. Jumping from a DA of 1 to 10 happens way faster than climbing from 40 to 50. The best approach is to focus on steady, consistent effort rather than chasing overnight success.

The key is consistency. A steady stream of authoritative links built over time sends a much stronger signal to search engines than a one-off campaign. You’re building trust, and that just takes time.

Is a Low Domain Authority Score Bad for My New SaaS?

Not at all. Every single website-even the biggest names you can think of-started with a Domain Authority of 1. A low score is simply the starting line, not a sign that you’ve done something wrong.

Search engines expect new sites to take time to earn credibility. So instead of stressing about that low initial number, pour your energy into building a rock-solid SEO foundation. That means creating genuinely helpful content that your target audience actually wants and systematically earning backlinks from relevant, respected sites. Think of your DA as a benchmark to measure your growth against competitors, not as a grade on your website’s value.

Should I Focus More on Domain Authority or Page Authority?

That’s a great question, and the answer is: you need to pay attention to both. They measure two different, but equally important, things.

• Domain Authority (DA): This is the big-picture metric. It gives you a sense of your entire website’s potential to rank in search results and is invaluable for keeping an eye on your competitors.
• Page Authority (PA): This one is much more specific, predicting the ranking strength of a single page. It’s perfect for figuring out which specific pieces of content-like that epic blog post or a go-to resource-are your heavy hitters.

A smart SaaS strategy uses both. Track your DA to monitor your site’s overall health and see how you stack up in your niche. At the same time, keep an eye on your PA to pinpoint which pages are attracting the best links and driving your authority. After all, a high Domain Authority is just the sum of many strong individual pages.
