What Is Domain Authority?
If you have spent any time researching SEO, you have probably come across the term domain authority. But what is domain authority exactly, and why does everyone in the digital marketing world keep talking about it?
Domain authority (DA) is a search engine ranking score originally developed by Moz. It predicts how likely a website is to rank on search engine results pages (SERPs). The score ranges from 1 to 100, with higher scores indicating a greater ability to rank.
Think of it this way: domain authority is like a credibility rating for your entire website. The stronger your DA, the more search engines view your site as a trustworthy, authoritative source of information.
It is important to note that domain authority is not a Google ranking factor. Google does not use Moz’s DA score in its algorithm. However, DA is a useful predictive metric that correlates strongly with actual search rankings, making it an excellent benchmarking tool for SEO professionals and business owners alike.
Domain Authority vs. Page Authority: What Is the Difference?
People often confuse domain authority with page authority. Here is a simple way to understand the difference:
| Metric | What It Measures | Scope |
|---|---|---|
| Domain Authority (DA) | The overall ranking strength of your entire website | Whole domain |
| Page Authority (PA) | The ranking strength of a single, specific page | Individual page |
A helpful analogy: your domain authority reflects the reputation of your entire house (the website), while page authority shows how well one specific room (a single page) performs. Both metrics matter, but DA gives you the big-picture view of your site’s SEO health.
How Is Domain Authority Calculated?
Moz calculates domain authority using a machine learning model that evaluates over 40 factors. While the exact algorithm is proprietary, we know the most influential factors include:
- Link profile quality – The number and quality of external websites linking back to your domain
- Linking root domains – How many unique domains link to you (diversity matters)
- MozRank and MozTrust – Moz’s own metrics that assess link popularity and trustworthiness
- Site structure and content quality – How well-organized and valuable your content is
- Spam score – Whether your backlink profile shows signs of manipulation
The DA score uses a logarithmic scale, which means it is much easier to grow your score from 10 to 20 than from 70 to 80. Every point becomes harder to earn as you climb higher.
Other Authority Metrics Worth Knowing
Moz is not the only company offering authority metrics. Here are some alternatives you may encounter:
| Tool | Metric Name | Scale |
|---|---|---|
| Moz | Domain Authority (DA) | 1-100 |
| Ahrefs | Domain Rating (DR) | 0-100 |
| Semrush | Authority Score (AS) | 0-100 |
| Majestic | Trust Flow / Citation Flow | 0-100 |
Each tool uses a slightly different methodology, so your scores will vary across platforms. The key is to pick one tool and track your progress consistently over time rather than comparing numbers from different providers.
What Is a Good Domain Authority Score?
There is no universal “good” DA score because it depends entirely on your niche and your competitors. However, here is a general guideline to help you understand where you stand:
| DA Score Range | Rating | Typical Examples |
|---|---|---|
| 1-10 | Very Low | Brand-new websites, recently launched blogs |
| 11-20 | Low | Small business sites with minimal link building |
| 21-40 | Below Average to Average | Growing businesses actively investing in content and SEO |
| 41-60 | Good | Well-established companies, popular industry blogs |
| 61-80 | Very Good | Large brands, high-traffic media sites |
| 81-100 | Excellent | Major platforms like Wikipedia, Google, Facebook |
The best way to evaluate your DA is to compare it against the websites you are competing with in search results. If your competitors have a DA of 35 and yours is 28, you know exactly what gap you need to close.
Why Does Domain Authority Matter for SEO?
Even though Google does not directly use DA as a ranking factor, domain authority matters for several important reasons:
- Benchmarking your SEO progress – DA gives you a single number to track over time so you can measure the impact of your link-building and content efforts.
- Competitive analysis – Comparing your DA against competitors helps you understand how much work is needed to outrank them.
- Evaluating link opportunities – When building backlinks, DA helps you assess whether a potential linking site is worth pursuing. A link from a DA 70 website carries far more weight than one from a DA 10 site.
- Predicting ranking potential – While not perfect, DA correlates well with actual rankings. Higher-DA sites tend to rank for more keywords and attract more organic traffic.
- Building trust with partners – Clients, advertisers, and business partners often use DA as a quick way to gauge a website’s credibility.

10 Actionable Strategies to Improve Your Domain Authority
Now for the part everyone wants to know: how do you actually increase your domain authority? Here are ten proven strategies that work in 2026 and beyond.
1. Earn High-Quality Backlinks
Backlinks remain the single most important factor in building domain authority. Focus on earning links from websites that are:
- Relevant to your industry or niche
- Themselves high in domain authority
- Editorially given (not bought or exchanged in bulk)
Guest posting on reputable publications, creating original research, and building relationships with journalists are all excellent ways to earn quality backlinks.
2. Create Link-Worthy Content
The best link-building strategy is to create content that people naturally want to reference and share. This includes:
- Original data studies and surveys
- Comprehensive industry guides
- Interactive tools and calculators
- Infographics and visual content
- Thought leadership pieces with unique insights
3. Diversify Your Backlink Profile
Google and authority metrics both reward a diverse link profile. Aim to get links from many different domains rather than many links from just a few sites. Ten links from ten different websites are far more valuable than ten links from one website.
4. Remove or Disavow Toxic Backlinks
Low-quality or spammy backlinks can drag your DA down. Regularly audit your backlink profile using tools like Moz, Ahrefs, or Google Search Console. If you find links from suspicious or irrelevant sites:
- Contact the webmaster and request removal
- If that fails, use Google’s Disavow Tool to tell Google to ignore those links
5. Optimize Your Internal Linking Structure
Internal links distribute authority throughout your website. Make sure every important page is linked from other relevant pages on your site. A clear, logical internal linking structure helps search engines understand your content hierarchy and passes authority from strong pages to weaker ones.
6. Publish Consistently and Build Topical Authority
Websites that publish high-quality content on a regular schedule tend to build authority faster. Focus on covering your core topics thoroughly. When you become the go-to resource for a specific subject area, both search engines and other websites naturally reward you with higher authority.
7. Improve Your Technical SEO
Technical issues can undermine your domain authority efforts. Make sure your website:
- Loads quickly (aim for under 2.5 seconds on Core Web Vitals)
- Is fully mobile-responsive
- Uses HTTPS across all pages
- Has a clean XML sitemap
- Is free of crawl errors and broken links
- Uses structured data where appropriate
8. Build Your Brand Presence
Brand signals are increasingly important for authority. The more people search for your brand name, mention you on social media, and cite your work in their content, the more authoritative your domain becomes. Invest in:
- Social media engagement
- PR and media mentions
- Speaking at conferences and events
- Podcast appearances
- Community building
9. Be Patient and Think Long-Term
Domain authority is not something you can boost overnight. It takes months or even years of consistent effort to see meaningful improvements. Set realistic goals. Aiming to improve your DA by 5 to 10 points over six months is ambitious but achievable for most businesses.
10. Monitor and Adapt
SEO is always evolving. Track your DA alongside other SEO metrics like organic traffic, keyword rankings, and referring domains. If your DA plateaus, revisit your strategy. Look at what your higher-authority competitors are doing and find ways to differentiate your approach.
Common Mistakes That Hurt Domain Authority
As you work on improving your DA, be careful to avoid these pitfalls:
- Buying backlinks in bulk – This can lead to a Google penalty and will harm your authority in the long run.
- Ignoring content quality – Thin, duplicated, or low-value content sends negative signals to search engines.
- Neglecting broken links – Both internal and external broken links create a poor user experience and waste link equity.
- Obsessing over the number – DA is a relative metric and one data point among many. Do not make it your only KPI.
- Using link schemes or private blog networks (PBNs) – These tactics might produce short-term gains but often result in penalties that are difficult to recover from.
Domain Authority in the Context of Modern SEO (2026 and Beyond)
Search engine optimization continues to evolve rapidly. With Google’s increasing emphasis on E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness), building genuine domain authority is more important than ever.
Here is what matters most in 2026:
- Quality over quantity – Both for content and backlinks, genuine quality wins over volume.
- Topical depth – Google rewards websites that demonstrate deep expertise in specific topics rather than superficial coverage of everything.
- User experience signals – Page speed, mobile usability, and engagement metrics all feed into how search engines perceive your site’s authority.
- AI-generated content caution – While AI tools can assist with content creation, search engines are getting better at detecting and devaluing low-effort, mass-produced content. Always add genuine expertise and human insight.
Frequently Asked Questions About Domain Authority
What is the domain authority of a website?
Domain authority is a score from 1 to 100, developed by Moz, that predicts how well a website is likely to rank in search engine results. It is calculated based on factors like backlink quality, linking root domains, and overall site trustworthiness.
Is a domain authority of 20 good?
A DA of 20 is typical for small business websites or newer sites that are starting to build their online presence. Whether it is “good” depends on your competitors. If most sites in your niche have a DA between 15 and 25, then 20 puts you right in the mix. The goal should always be to have a higher DA than the sites you are trying to outrank.
What is a good domain authority score?
There is no absolute answer because DA is a comparative metric. Generally, scores above 40 are considered solid, and scores above 60 are very strong. But the most meaningful benchmark is your direct competitors. If you can match or exceed their DA while producing better content, you are in a strong position.
Does Google use domain authority as a ranking factor?
No. Domain authority is a third-party metric created by Moz. Google has its own internal metrics and algorithms. However, the factors that contribute to a high DA (quality backlinks, good content, strong technical SEO) are very much aligned with what Google values.
How long does it take to improve domain authority?
It depends on your starting point and the competitiveness of your niche. Most websites can expect to see noticeable DA improvements within 3 to 6 months of consistent, focused effort on content creation and link building. However, reaching the higher end of the scale (60+) can take years.
Can domain authority go down?
Yes. Your DA can decrease if you lose backlinks, if competitors gain more links, or if Moz updates their algorithm. A sudden drop is not always cause for alarm. Check whether it coincides with a Moz index update before taking drastic action.
What is the difference between domain authority and domain rating?
Domain Authority (DA) is Moz’s metric, while Domain Rating (DR) is the equivalent metric from Ahrefs. Both measure similar concepts but use different calculation methods and data sets. Your DA and DR scores for the same website will likely be different numbers.
Final Thoughts
Understanding what domain authority is and how to improve it gives you a real advantage in your SEO strategy. While DA is not a perfect metric, it serves as an excellent compass for guiding your efforts and measuring progress over time.
Focus on the fundamentals: create exceptional content, earn quality backlinks from diverse sources, maintain a technically sound website, and be patient. Domain authority grows as a natural byproduct of doing SEO well.
