What Is Domain Authority (DA) and How Does It Impact SEO?

Imagine this: You’ve poured your heart and soul into building your website. The design looks amazing, your content is thoughtful and valuable — yet somehow, your competitors still seem to outrank you on Google. Frustrating, right? So, what’s their secret weapon? More often than not, it’s something called Domain Authority.

In the fierce competition for search rankings, Domain Authority (DA) isn’t just another SEO buzzword — it’s a behind-the-scenes powerhouse that can either push your website to Google’s front page or bury it somewhere in the depths of page two (or worse). Whether you’re a seasoned SEO pro or just starting to explore the world of search optimization, understanding this metric could be the game-changer you need to stand out.

But why does Domain Authority matter so much? Is it really the magic number that decides your site’s fate? And more importantly — how can you improve it to boost your website’s performance?

In this article, we’ll break down what Domain Authority is, why it’s so important, and how you can use it to gain a competitive edge in the ever-crowded digital landscape.

What is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). Domain Authority scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking.

Think of Domain Authority as a “strength score” for your website. Just as a thermometer measures temperature, DA measures the potential ranking power of your entire domain. This predictive metric helps you understand where your website stands in the competitive digital landscape and how likely it is to appear in relevant search results.

The actual Domain Authority calculation itself uses a machine learning model to predictively find a “best fit” algorithm that most closely correlates link data with rankings across thousands of actual search results that are used as standards to scale against.

It’s important to note: Domain Authority is not a Google ranking factor. Rather, it’s a third-party metric designed to approximate how Google might evaluate domains based on their link profiles and overall SEO health.

How is Domain Authority Calculated?

Domain Authority is calculated by evaluating multiple factors, including linking root domains and the total number of links, into a single DA score. A domain’s DA score is calculated using a machine learning algorithm that predicts how frequently a domain appears in Google’s search results compared to its competitors.

Sites with higher numbers of unique referring domains are more likely to achieve better DA scores, indicating a stronger backlink profile and potentially higher ranking potential in search engines. This score can then be used when comparing websites or tracking the “ranking strength” of a website over time.

As of the Domain Authority 2.0 update in early 2019, the calculation of a domain’s DA score comes from a machine learning algorithm’s predictions about how often Google is using that domain in its search results. If domain A is more likely to appear in a Google SERP than domain B is, then we would expect domain A’s DA to be higher than domain B’s DA.

Since DA is based on machine learning calculations, your site’s score will often fluctuate as more, fewer, or different data points become available and are incorporated into those calculations. For instance, if Facebook were to acquire a billion new links, every other site’s DA would drop relative to Facebook’s.

Because more established and authoritative domains like Facebook will have increasingly larger link profiles, they take up more of the high-DA slots, leaving less room at the higher end of the scale for other domains with less robust link profiles. Therefore, it’s significantly easier to grow your score from 20 to 30 than it is to grow it from 70 to 80. For this reason, it’s important to use Domain Authority as a comparative metric rather than an absolute one.

Domain Authority vs. Page Authority: Understanding the Difference

While Domain Authority measures the predictive ranking strength of entire domains or subdomains, Page Authority measures the strength of individual pages. To illustrate this difference:

Domain Authority (DA):

• Evaluates the strength of the entire domain
• Predicts how well any page on that domain might rank
• Considers all links pointing to any page on your domain
• Example: guide.zuptek.com might have a DA of 45

Page Authority (PA):

• Evaluates the strength of a single URL
• Predicts how well that specific page might rank
• Considers only links pointing to that particular page
• Example: guide.zuptek.com/what-is-seo might have a PA of 52
  

Think of it this way: if your website were a city, Domain Authority would be the city’s overall reputation and infrastructure, while Page Authority would be the quality and accessibility of individual buildings within that city.

The Role of Linking Root Domains in Domain Authority

Linking root domains play a crucial role in determining a website’s Domain Authority (DA) score. A linking root domain is a unique domain that links to a website, and the number of these domains is a key factor in calculating DA. Essentially, it indicates the diversity and quality of a website’s backlink profile.

A high number of linking root domains can positively impact a website’s DA score, suggesting that the website is widely recognized and respected within its industry. Conversely, a low number of linking root domains can negatively affect a website’s DA score, potentially indicating a lack of credibility and trustworthiness.

To illustrate with an example:

1. Website A has 100 backlinks from 5 different domains
2. Website B has 50 backlinks from 30 different domains

Despite having fewer total backlinks, Website B might have a higher Domain Authority because the diversity of linking domains suggests broader recognition and relevance. This demonstrates why focusing solely on the quantity of backlinks isn’t an effective strategy.

To increase the number of linking root domains, website owners should focus on creating high-quality, relevant, and valuable content that naturally attracts links from other websites. Engaging in link-building strategies such as guest blogging, broken link building, and resource page link building can also be effective. By diversifying and enhancing your backlink profile, you can improve your domain authority and strengthen your site’s overall SEO performance.

What is a Good Domain Authority Score?

This is a very common question in the SEO industry. As with any SEO metrics, the first thing you’ll want to understand: “is a domain authority score of 30 any good? Or could be better?” And as with every SEO question there is a suitable SEO answer: it depends.

There isn’t really a single specific number you want to achieve, so being realistic and setting achievable goals based on your resources, your competitors, and specific ranking objectives can help you grow your authority in a sustainable way.

A brand-new website will always start with a Domain Authority score of one, and that score will increase as the site earns more and more authoritative backlinks over time.

Remember that sites with very large numbers of high-quality external links will have a higher Domain Authority, whereas small businesses and websites with fewer inbound links may have much lower DA scores.

Here’s a general breakdown of Domain Authority scores:

• 1-20: New websites or small local businesses without many backlinks
• 20-40: Established small to medium-sized websites with decent backlink profiles
• 40-60: Larger websites with strong content and established authority in their niche
• 60-80: Very authoritative websites, often industry leaders
• 80-100: The highest authority websites on the internet (think Wikipedia, Google, Facebook)

Because Domain Authority is a predictor of a site’s ability to rank within its unique competitive landscape, you shouldn’t choose your target DA in a vacuum. Look at the DA scores for the sites you compete with directly in the SERPs and aim for a higher score than your competitors.

DA is best used as a comparative metric when investigating the sites within your target SERPs that may have more powerful link profiles than you do — your true competitors. Because the metric is relative, there is no such thing as an absolutely “good,” “average,” or “bad” Domain Authority score; there are only scores that are “good,” “average,” or “bad” within the context of a particular competitive landscape.

How Domain Authority Impacts SEO Performance

Domain Authority serves as a valuable indicator of your website’s potential to rank well in search engine results. While it’s not a direct ranking factor used by Google, it correlates strongly with search engine success for several reasons:

1. Competitive Analysis and Benchmarking

DA allows you to compare your site’s strength against competitors targeting the same keywords. For example, if you’re trying to rank for “beginner SEO tips” and your competitors have DAs of 45-60 while yours is 30, you might need to:

• Focus on building more quality backlinks
• Create exceptionally valuable content to overcome the authority gap
• Consider targeting longer-tail, less competitive keywords initially

2. Identifying Link-Building Opportunities

A higher Domain Authority often translates to better ranking potential, making DA an excellent metric for prioritizing link-building efforts. When seeking guest posting or partnership opportunities, targeting sites with DAs higher than yours (but not astronomically higher) often offers the best return on investment.

3. Measuring SEO Progress Over Time

Tracking your DA over months and years provides a broad measure of your SEO success. While fluctuations are normal, a general upward trend indicates your link-building and content strategies are working.

4. Setting Realistic SEO Goals

Understanding DA helps set attainable objectives. If your site has a DA of 25, aiming to outrank a competitor with a DA of 75 for a competitive term may not be realistic in the short term. Instead, you might focus on:

• Long-tail keywords with less competition
• Building authority within a specific niche
• Creating content so exceptional it attracts natural backlinks

5. Predicting Ranking Difficulties

When conducting keyword research, considering the DA of currently ranking sites helps estimate how difficult it will be to rank for those terms. This allows for more strategic content planning.

Real-World Example: Let’s say you run an SEO blog with a DA of 35. You’re considering creating comprehensive guides on either “advanced technical SEO audits” or “SEO tips for beginners.” Upon analysis, you find that the top 10 results for the technical SEO topic have DAs ranging from 60-85, while the beginner SEO results show DAs between 30-45. This insight might lead you to prioritize the beginner content while building authority to eventually compete for the technical topic.

Common Misconceptions About Domain Authority

There are several common misconceptions about Domain Authority (DA) that can lead to confusion and misinterpretation. Here are the most prevalent myths debunked:

Misconception 1: DA is a Direct Ranking Factor Used by Google

Reality: DA is a third-party metric developed by Moz to predict a website’s ranking potential. Google has confirmed they don’t use Moz’s Domain Authority in their ranking algorithm. Rather, DA attempts to approximate how Google might evaluate domains based on link profiles and overall SEO health.

Misconception 2: A High DA Guarantees High Rankings

Reality: While a higher DA correlates with better ranking potential, it doesn’t guarantee rankings for specific keywords. A site with a lower DA but with content highly optimized for a specific query and strong topical relevance might outrank a higher DA site that’s less relevant to the query.

Example: A specialized medical blog with a DA of 40 might outrank a general news site with a DA of 70 for specific medical terms because of its topical expertise and content depth.

Misconception 3: DA is Fixed and Changes Slowly

Reality: DA is recalculated regularly and can fluctuate significantly based on:

• Changes to Moz’s algorithm
• Updates to their link index
• Relative changes in other websites’ authority

If major websites gain many new links, other sites might see DA drops even without any negative changes to their own link profiles.

Misconception 4: DA is the Same as PageRank or Other Metrics

Reality: DA differs from Google’s PageRank (which is no longer publicly updated) and from similar metrics by other SEO tools like Ahrefs’ Domain Rating (DR) or Majestic’s Trust Flow. Each uses different data sources and calculation methods. While these metrics often correlate, they shouldn’t be used interchangeably.

Misconception 5: Focusing Only on DA Will Improve Rankings

Reality: Obsessing over DA while neglecting other crucial SEO factors (like content quality, user experience, and technical SEO) is a common mistake. Domain Authority should be just one component of a comprehensive SEO strategy.

Understanding these misconceptions helps SEO professionals and website owners use Domain Authority more effectively as part of a holistic approach to search engine optimization.

How to Improve Your Domain Authority

The best way to increase domain authority is to improve your site’s overall SEO health, with a particular focus on the quality and quantity of external links pointing to your site.

Because Domain Authority aggregates so many pieces of data, it can be difficult to influence directly. This metric is meant to predict how competitive a given site will be in Google search results, and since Google considers so many ranking factors in determining its rankings, a metric that tries to approximate its determinations must incorporate a similar number and complexity of factors.

Here are actionable strategies to improve your Domain Authority:

1. Build a Strong Backlink Profile

Focus on quality over quantity: A few links from authoritative, relevant websites will boost your DA more than many low-quality links.

Pursue diverse linking sources: Aim to get backlinks from a variety of unique domains rather than multiple links from the same few sites.

Create linkable assets: Develop comprehensive guides, original research, infographics, and tools that naturally attract links from other websites.

Example strategy: Create an annual industry survey with original data that becomes a reference point for others in your field.

2. Create High-Quality, Semantically Rich Content

Develop comprehensive topic coverage: Use topic clustering to create content that thoroughly covers your niche. Create pillar content supported by related articles that link back to the main resource.

Incorporate semantic SEO principles: Use related terms, synonyms, and semantically connected words to enhance context while avoiding keyword stuffing.

Focus on E-E-A-T: Demonstrate Experience, Expertise, Authoritativeness, and Trustworthiness in your content, especially for YMYL (Your Money Your Life) topics.

Example implementation: A comprehensive guide on “Beginner’s SEO” could include semantically related subtopics like “keyword research basics,” “on-page optimization for beginners,” and “understanding search intent,” all interlinked and supporting the main pillar page.

3. Optimize Technical SEO Factors

Improve site speed: Faster-loading websites tend to perform better in search and acquire more links.

Ensure mobile responsiveness: With mobile-first indexing, having a mobile-friendly site is crucial.

Fix crawlability issues: Use proper site architecture, fix broken links, and implement correct canonicalization to help search engines properly index your content.

Example tool usage: Regular technical audits using tools like Screaming Frog can help identify and fix crawlability issues that might be holding back your DA growth.

4. Remove Toxic Backlinks

Conduct regular backlink audits: Identify and disavow toxic or spammy links that could be harming your site’s authority.

Focus on natural link profiles: Avoid artificial link schemes that violate Google’s guidelines and could result in penalties.

5. Build Brand Authority

Establish thought leadership: Publish expert content on your site and contribute guest posts to respected industry publications.

Participate in your community: Answer questions on forums like Quora, contribute to discussions on Reddit, and engage with your industry on social media.

Earn mentions and citations: Build relationships with journalists and industry analysts to earn brand mentions even without links.

Remember that improving Domain Authority is a long-term process. Focus on creating value for your audience through quality content and user experience, and the authority will follow naturally as your site earns recognition and links from others in your industry.

Domain Authority Best Practices for SEO

To effectively leverage Domain Authority in your SEO strategy, follow these best practices:

1. Use DA as a Comparative Metric, Not an Absolute Score

Do: Compare your DA to direct competitors targeting the same keywords. Don’t: Fixate on reaching a specific DA number without context.

Implementation tip: Create a spreadsheet tracking your DA alongside 5-10 key competitors, monitoring changes over time to identify trends.

2. Focus on Relevant, High-Quality Backlinks

Do: Earn links from authoritative sites in your niche. Don’t: Use link farms, paid link schemes, or irrelevant links to artificially inflate DA.

Example strategy: If you run an SEO blog like guide.zuptek.com, prioritize earning links from reputable digital marketing blogs, industry associations, and educational institutions over random high-DA sites with no topical relevance.

3. Build a Comprehensive Content Strategy

Do: Create topic clusters with semantically related content that demonstrates expertise. Don’t: Produce thin content targeting only keywords without providing value.

Implementation approach: For the topic “Domain Authority,” create a comprehensive pillar page (like this one) supported by related content about backlink building, technical SEO factors affecting DA, and competitor analysis methods.

4. Monitor DA Changes After Major Updates

Do: Track DA fluctuations after Moz algorithm updates or major Google algorithm changes. Don’t: Panic over small DA fluctuations, which are normal.

Practical tip: Set calendar reminders to check DA metrics quarterly, documenting any significant changes and correlating them with specific SEO activities or known algorithm updates.

5. Balance DA with Other Important SEO Metrics

Do: Consider DA alongside other metrics like organic traffic, keyword rankings, and conversion rates. Don’t: Make business decisions based solely on DA.

Example dashboard: Create a monthly SEO health dashboard that includes:

• Domain Authority trend
• Organic traffic growth
• Conversion rates from organic traffic
• Visibility for target keywords
• Page load speed metrics
• Mobile usability scores

By following these best practices, you’ll use Domain Authority effectively as one component of a comprehensive SEO strategy, rather than treating it as the ultimate goal.

How Different Industries Are Affected by Domain Authority

Domain Authority impacts different industries in various ways due to the competitive landscape, user behavior, and typical link acquisition patterns unique to each sector. Understanding these differences can help you set realistic goals and develop more effective strategies.

E-commerce

Typical DA range for success: 30-60 Key challenges: High competition from major retailers (Amazon, Walmart) with DAs of 90+ Strategic focus: Building authority through product reviews, specialized guides, and niche expertise

Example: A specialized outdoor gear e-commerce site might never reach the DA of Amazon, but can compete effectively for long-tail product queries by building deep content around specific activities like “ultralight backpacking gear” or “winter camping equipment” and earning links from outdoor enthusiast blogs and magazines.

Healthcare and Medical Websites

Typical DA range for success: 40-70 Key challenges: YMYL (Your Money Your Life) classification requires exceptional E-E-A-T signals Strategic focus: Demonstrating expertise through credentials, research citations, and authoritative linking domains

Industry note: Medical sites often need higher DA to rank due to Google’s emphasis on authority in health topics. A doctor’s private practice might focus on earning links from hospital associations, medical journals, and health organizations to build the necessary authority.

Local Businesses

Typical DA range for success: 20-40 Key challenges: Competing with directories and aggregators (Yelp, TripAdvisor) that have very high DAs Strategic focus: Local link building, industry-specific directories, and community involvement

Local strategy example: A local plumbing company might never reach a high global DA, but can dominate local search by earning links from chamber of commerce websites, local news outlets, and community event sponsorships.

SaaS and Technology

Typical DA range for success: 35-65 Key challenges: Rapidly changing landscape with frequent new competitors Strategic focus: Thought leadership content, product comparisons, and technical resources that earn links from tech publications

Example approach: A SaaS company might build authority through publishing original research, creating free tools, and developing comprehensive guides that become industry references.

Educational Resources

Typical DA range for success: 30-60 Key challenges: Competing with established educational institutions with very high DAs Strategic focus: Creating exceptional, citable resources and building relationships with educators and researchers

Example strategy: An educational website like guide.zuptek.com focusing on SEO education might target links from marketing courses, digital skills training programs, and industry certification bodies.

Understanding these industry differences helps set appropriate DA goals and develop strategies that acknowledge the unique challenges and opportunities in your specific sector.

Domain Authority Impact on Different Types of SEO

Domain Authority influences various aspects of SEO in different ways. Understanding these relationships helps create more effective optimization strategies.

On-Page SEO and Domain Authority

While DA primarily reflects off-page factors, it can affect how search engines interpret your on-page optimization:

Content Authority: Higher DA sites often have their content taken more seriously, even for new topics. Keyword Competitiveness: Higher DA allows you to compete for more difficult keywords with less intensive on-page optimization. Indexing Speed: Higher authority sites often see new content indexed more quickly.

Strategic approach: For lower DA sites, compensate with exceptional on-page optimization, including comprehensive keyword coverage, semantic richness, and structured data markup.

Technical SEO and Domain Authority

Technical SEO and DA have a reciprocal relationship:

Crawl Budget: Higher DA sites typically receive more generous crawl budgets from search engines. Site Structure Impact: Good technical SEO can maximize the flow of link equity throughout your site, effectively leveraging your domain authority. Core Web Vitals: Technical performance metrics can influence user engagement, which indirectly affects link acquisition and DA growth.

Implementation tip: Lower DA sites should be extra vigilant about technical SEO issues, as they have less authority to compensate for technical problems.

Local SEO and Domain Authority

In local SEO, Domain Authority interacts with proximity and relevance factors:

Local Pack Rankings: While proximity is critical, higher DA can help dominate local results beyond the immediate vicinity. Local Link Value: Links from local news sites and community organizations carry special weight for local rankings, sometimes outperforming higher DA non-local links.

Example strategy: A local business might prioritize earning links from regional chambers of commerce, business associations, and local news outlets over national publications with higher DA but less local relevance.

E-commerce SEO and Domain Authority

For online stores, DA impacts product visibility and category competitiveness:

Category Page Competition: Higher DA helps compete for broad category terms like “men’s shoes” or “office furniture.” Product Page Rankings: Individual product pages on higher DA sites often rank better, even with fewer product-specific links. Review Snippets: Higher DA sites may be more likely to earn review snippets in search results.

Strategic application: E-commerce sites with lower DA should focus on long-tail product terms and niche categories while building authority to eventually compete for broader terms.

Understanding these relationships allows you to adapt your SEO strategy to leverage your current Domain Authority while working to improve it over time.

Tracking Domain Authority: Tools and Methods

Effectively monitoring your Domain Authority over time is essential for measuring progress and identifying opportunities for improvement. Here are the best tools and methods for tracking DA:

Free Tools for Basic DA Tracking

1. Moz Link Explorer: Offers 10 free queries per month to check DA, PA, and basic link metrics
2. MozBar: Free browser extension showing DA and page metrics while browsing
3. Moz DA Checker: Simple tool for quick DA lookups

Implementation tip: Even with limited free checks, establish a monthly routine to track your core domain and top competitors.

Comprehensive Paid Solutions

1. Moz Pro: The official source for DA metrics with comprehensive tracking, competitor analysis, and link insights
2. SEMrush: Offers DA alongside their own Authority Score and comprehensive SEO toolset
3. Ahrefs: While using their own Domain Rating metric, provides excellent backlink analysis to help improve factors affecting DA

Feature comparison: Moz Pro provides the most accurate DA tracking (being the creator of the metric), while SEMrush and Ahrefs offer broader SEO capabilities with slightly different authority metrics.

Setting Up Effective DA Tracking Systems

To maximize the value of DA tracking:

1. Create a tracking spreadsheet: Record DA scores monthly for your domain and key competitors
2. Document major site changes: Note when significant updates occur (redesigns, content overhauls, link building campaigns)
3. Track correlation with other metrics: Monitor how DA changes correlate with organic traffic, rankings, and conversions

Example tracking setup:

• Monthly DA checkpoint (1st of each month)
• Quarterly competitor analysis comparing DA trends
• Link acquisition log tracking new high-value backlinks
• Annotation of major Google updates and their impact on DA

DA Fluctuation Analysis

Understanding why your DA changes helps inform your strategy:

Normal fluctuations: DA typically fluctuates 1-3 points naturally due to Moz’s index updates Significant drops: A drop of 5+ points might indicate lost backlinks or algorithm changes Steady increases: Consistent growth of 1-2 points monthly suggests effective link building

Analysis approach: When you notice significant DA changes, check:

1. Recent backlink acquisition or loss
2. Changes to high-authority sites in your industry
3. Updates to Moz’s DA algorithm
4. Major Google algorithm updates that might affect link valuation

By systematically tracking and analyzing your Domain Authority, you transform this metric from a vanity number into an actionable insight that guides your SEO strategy.

FAQs About Domain Authority

1. What’s the difference between Domain Authority and PageRank?

Answer: Domain Authority (DA) is a metric developed by Moz that predicts a website’s ability to rank in search results based on a 1-100 scale, considering multiple factors with an emphasis on the link profile. PageRank was Google’s original algorithm for ranking pages based on their link popularity, but Google no longer publicly updates PageRank scores. While both measure authority through links, DA is more comprehensive, incorporating more factors and providing a comparative score that’s regularly updated.

2. How quickly can I improve my Domain Authority?

Answer: Domain Authority typically improves gradually over months rather than days or weeks. New websites generally start with a DA of 1 and might take 3-6 months of consistent link building to reach the 20-30 range. Moving from DA 30 to 40 might take another year of strategic effort. The higher your current DA, the more difficult and time-consuming further improvements become. Focus on consistent quality rather than quick gains, as rapid DA increases through aggressive tactics often lead to penalties.

3. Does Domain Authority affect my Google rankings directly?

Answer: No, Domain Authority is not a Google ranking factor and does not directly affect your rankings in Google search results. DA is a third-party metric created by Moz to predict ranking potential. However, many of the factors that contribute to a higher DA (quality backlinks, site authority, etc.) are similar to what Google considers in its ranking algorithm. This creates a correlation between higher DA and better rankings, even though the relationship is not causal.

4. How often does Domain Authority update?

Answer: Moz updates its Domain Authority scores approximately monthly, though the exact timing can vary. These updates reflect changes in Moz’s link index and sometimes adjustments to the DA algorithm itself. Your DA may fluctuate between updates as Moz discovers new links or removes old ones from its index. Major updates to the DA algorithm are less frequent, with the last significant change being the rollout of Domain Authority 2.0 in March 2019.

5. Can I have a higher Domain Authority than websites with more backlinks?

Answer: Yes, it’s possible to have a higher DA than sites with more raw backlinks because DA prioritizes quality and diversity of linking domains over sheer quantity of links. A site with 100 high-quality backlinks from 100 different authoritative domains will typically have a higher DA than a site with 1,000 low-quality links from only a few domains. This reflects how modern search engines evaluate link profiles, emphasizing the authority and relevance of linking sites rather than just counting links.

7. Does having a subdomain affect Domain Authority?

Answer: Subdomains (like blog.example.com) typically develop their own Domain Authority separate from the main domain (example.com). This means a subdomain starts with its own DA and builds authority based on its specific link profile. In some cases, especially for well-established domains, some authority may pass between the main domain and subdomains, but they’re generally treated as separate entities. If building authority is your primary goal, using subdirectories (example.com/blog) instead of subdomains may be more beneficial as they share the main domain’s authority.

8. How does Domain Authority relate to local SEO?

Answer: For local SEO, Domain Authority is one factor among many that influence rankings. Local search results are heavily influenced by proximity, relevance, and prominence factors specific to Google’s local algorithm. A business with lower DA but strong local signals (Google Business Profile optimization, local citations, reviews) can outrank higher DA competitors for location-based searches. However, higher DA can give you an edge when competing against similarly optimized local businesses, especially for broader regional terms.
