Domain Authority: The Complete Guide for 2026

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 results pages (SERPs). DA scores range from 1 to 100, with higher scores corresponding to a greater likelihood of ranking.

It is important to understand that DA is not a Google ranking factor. Google has confirmed they do not use any third-party authority metric in their algorithm. However, DA is an extremely useful comparative metric — it helps you understand how your site stacks up against competitors and track your SEO progress over time.

Think of DA as a weather forecast for SEO: it does not guarantee results, but it gives you a reliable prediction based on available data.

How Is Domain Authority Calculated?

Moz calculates Domain Authority using a machine learning model that evaluates multiple factors and compares your domain's link profile against thousands of real-world search results. The main factors include:

Linking root domains — The number of unique websites that link to your domain. This is the single most important factor. Having 100 backlinks from one website counts as just 1 root domain. Diversity matters more than volume.

Total number of backlinks — The overall count of inbound links pointing to your site. Quality matters more than quantity here.

MozRank and MozTrust — Moz's proprietary metrics that measure link popularity and link trust. MozRank looks at the quality of pages linking to you, while MozTrust evaluates the trustworthiness of those links based on how close they are to known trusted sources.

Spam Score — Moz analyzes your backlink profile for patterns that correlate with sites that have been penalized or banned by Google. A high spam score can drag your DA down significantly.

You can check both your DA and MozRank simultaneously using our free Moz Rank Checker.

Domain Authority vs. Page Authority

While Domain Authority measures the ranking strength of an entire domain (including all subdomains), Page Authority (PA) predicts the ranking strength of a single specific page.

Both metrics use similar factors, but their scope is different:

Metric	Scope	Best For
Domain Authority (DA)	Entire website	Competitor comparison, overall site health
Page Authority (PA)	Single page	Evaluating individual content performance

For a comprehensive picture, check both metrics at once with our DA PA Checker — it shows Domain Authority and Page Authority side by side for any URL.

You can also check Page Authority separately using our Page Authority Checker.

What Is a Good Domain Authority Score?

There is no universal "good" DA score — it depends entirely on your niche and competition. Here is a general framework:

DA Range	Category	Examples
1–20	New or small websites	New blogs, local businesses, startups
21–40	Growing websites	Established small businesses, niche blogs
41–60	Well-established sites	Popular blogs, medium businesses, news sites
61–80	High-authority domains	Major publications, large companies
81–100	Top-tier domains	Google, Facebook, Wikipedia, Amazon

The key insight: DA is comparative, not absolute. A DA of 30 might be excellent if your competitors are all at 15–25. Focus on outscoring your direct competitors rather than chasing an arbitrary number.

Why New Websites Have Low DA

If you just launched a website, expect a DA between 1 and 15. This is completely normal. DA is heavily influenced by your backlink profile, and new sites simply have not had time to accumulate quality links. Do not be discouraged — focus on creating great content and building links naturally.

How to Check Domain Authority (Free)

You do not need expensive tools to check Domain Authority. Here are free methods:

1. FreeGetStats Domain Authority Checker

Our free Domain Authority Checker gives you instant results. Just enter any URL and get:

• Domain Authority score
• Number of linking domains

2. Check DA and PA Together

Use our DA PA Checker to see both Domain Authority and Page Authority in one view. This is especially useful when you want to compare the strength of a specific page against the overall domain.

3. Analyze Your Backlink Profile

Since backlinks are the primary driver of DA, understanding your link profile is crucial. Our Backlink Checker shows you who is linking to your site, helping you understand what is driving (or holding back) your authority score.

Domain Authority Alternatives

Moz's DA is not the only authority metric available. Other SEO platforms have developed their own versions:

Metric	Provider	Scale
Domain Authority (DA)	Moz	1–100
Domain Rating (DR)	Ahrefs	1–100
Authority Score (AS)	Semrush	1–100
Domain Power (DP)	SearchAtlas	1–100

Each platform uses its own algorithm and link index, so scores can vary significantly across tools. The most important rule: pick one metric and stick with it for consistent tracking. Switching between tools will give you misleading fluctuations.

10 Proven Ways to Improve Domain Authority

While you cannot directly manipulate your DA score, you can improve the factors that influence it. Here are battle-tested strategies:

1. Build High-Quality Backlinks

This is the most impactful strategy. Focus on earning links from authoritative, relevant websites. Quality always beats quantity — one link from a DA 70 site is worth more than 100 links from DA 10 sites.

Tactics that work: guest posting on industry blogs, creating original research and data studies, building free tools and resources, HARO (Help a Reporter Out) responses, and broken link building.

Use our Backlink Checker to monitor your progress and identify new linking domains.

2. Create Link-Worthy Content

The best backlink strategy is creating content so valuable that people want to link to it. Focus on:

• Original research — surveys, data analysis, industry benchmarks
• Comprehensive guides — the definitive resource on a topic
• Free tools and calculators — interactive resources people reference
• Infographics and visual data — easy to share and embed

3. Improve Your Internal Linking

Internal links help distribute link equity across your site. When one page earns strong backlinks, linking from that page to other important pages on your site helps lift them too. Create a logical site structure where every important page is reachable within 3 clicks from the homepage.

4. Remove Toxic Backlinks

Low-quality, spammy backlinks can hurt your DA and potentially trigger Google penalties. Regularly audit your backlink profile using our Backlink Checker and disavow harmful links through Google Search Console.

Signs of a toxic backlink: comes from a site with very high spam score, from an irrelevant foreign-language site, from a known link farm, or uses exact-match anchor text excessively.

5. Optimize Technical SEO

A technically sound website creates a strong foundation for authority building:

• Site speed — Fast-loading sites provide better user experience and are more likely to be linked to. Check yours with our Website Speed Checker.
• SSL certificate — HTTPS is a trust signal. Verify your setup with our SSL Certificate Checker.
• Mobile-friendliness — Google uses mobile-first indexing.
• Clean URL structure — Use descriptive, keyword-rich URLs.
• Fix broken links and redirects — Check with our Redirect Checker.

6. Optimize On-Page SEO

Well-optimized pages rank better, attract more traffic, and earn more natural backlinks. Use our Meta Tags Analyzer to audit your title tags, meta descriptions, and heading structure. Then use our Meta Tag Generator to create optimized tags.

7. Get Listed in Business Directories

Online directories provide legitimate, relevant backlinks. Start with Google Business Profile, Yelp, industry-specific directories, and local business listings. These citations help establish trust and provide diverse root domains linking to your site.

8. Leverage Social Media and Content Promotion

While social links do not directly impact DA, social visibility leads to more people discovering and linking to your content. Promote every piece of content across relevant platforms — LinkedIn for B2B, Twitter for tech and news, Pinterest for visual content.

9. Be Patient and Consistent

DA does not change overnight. Moz updates their link index periodically, and meaningful improvements typically take 2–6 months of consistent effort. Track your progress monthly, not daily.

10. Monitor Your Competitors

Check your competitors' DA regularly to understand the competitive landscape. Use our Domain Authority Checker to compare scores. If a competitor's DA is growing faster than yours, investigate what they are doing differently — are they publishing more content? Earning more backlinks? Launching new features?

Common Domain Authority Myths

Myth 1: Google uses Domain Authority as a ranking factor

False. Google has explicitly stated they do not use any third-party authority metric. DA is a third-party prediction, not a Google metric. However, the factors that influence DA (backlinks, content quality) are also important for Google rankings.

Myth 2: A higher DA guarantees higher rankings

Not always. Google's algorithm considers hundreds of factors including content relevance, user intent, freshness, and page-level signals. A page on a DA 25 site can outrank a page on a DA 70 site if it better answers the search query.

Myth 3: You can quickly boost DA by buying links

Buying links violates Google's guidelines and can result in penalties. Even if it temporarily increases DA, the risk far outweighs the reward. Focus on earning links through valuable content and genuine relationships.

Myth 4: DA only goes up

DA can decrease. This happens when you lose backlinks, when linking sites lose their own authority, when Moz updates their algorithm, or when competitors improve faster than you. Regular monitoring helps you catch and address drops early.

How Often Should You Check Domain Authority?

Checking DA weekly or daily is unnecessary — the score does not change that frequently. Here is a recommended schedule:

• Monthly — Check your own site's DA and top competitors
• Quarterly — Do a comprehensive backlink audit
• Before major decisions — Check DA when evaluating potential link partners, guest post targets, or acquisition opportunities

Domain Authority and the Future of SEO

As search evolves with AI Overviews, ChatGPT, and Perplexity, the concept of authority is becoming even more important. AI systems tend to cite and reference authoritative sources — sites with strong backlink profiles, established trust signals, and comprehensive content.

Building genuine authority is not just about a Moz score anymore. It is about establishing your site as a trusted, go-to resource in your niche. The fundamentals remain the same: create exceptional content, earn quality backlinks, maintain technical excellence, and provide real value to your audience.
