Complete Guide to Domain Authority
Understand, check, and improve your website's authority score
What Is Domain Authority And How Is It Calculated?
Our domain authority checker tool enables you to reveal the domain authority and page authority of up to 3 domains per check. This tool allows you to bulk check domain authority, making it perfect for competitive analysis and portfolio audits.
Domain authority ratings are changed regularly so ensure you check your website's rating often. What grade does your website get? The higher the authority the better. Higher authority typically points to a greater chance of ranking in search engines for desired terms.
Developed by Moz, Domain Authority uses machine learning algorithms that analyze dozens of ranking factors including linking root domains, total backlinks, MozRank, and MozTrust. The score is logarithmic — moving from 20 to 30 is easier than moving from 70 to 80. For comprehensive SEO tracking, Moz Pro's rank tracking helps you monitor both DA changes and keyword position movements over time.
Real Domain Authority Examples
Wondering what a "good" DA score looks like? Here are real-world examples from major websites to give you context:
The gold standard
Major news authority
Knowledge hub
Established media
E-commerce giant
Professional network
Pro Tip: Most websites fall in the 20-60 DA range. A new site typically starts at DA 1, while established niche sites often reach DA 30-50. Don't compare yourself to Google — compare yourself to your direct competitors.
Domain Authority vs Domain Rating vs Authority Score
Confused by all the different authority metrics? Here's how the major scores compare:
| Metric | Provider | Scale | What It Measures |
|---|---|---|---|
| Domain Authority (DA) | Moz | 1-100 | Predicts ranking potential based on link profile strength |
| Domain Rating (DR) | Ahrefs | 1-100 | Strength of backlink profile relative to others in database |
| Authority Score | Semrush | 1-100 | Combines backlink data, organic traffic & spam factors |
| Page Authority (PA) | Moz | 1-100 | Same as DA but for individual pages, not domains |
Which one should you use?
DA is best for predicting Google ranking potential. DR focuses purely on backlink strength. Authority Score adds traffic data. Most SEOs track DA + DR together for the complete picture. Want to compare all these metrics side by side? Use our Backlink Analyzer to check DA, DR, and Authority Score for any domain in one place.
Do scores match across tools?
Not exactly. Each tool uses different data sources and algorithms. A site with DA 50 might have DR 65 or Authority Score 45. Compare within the same tool, not across tools.
How Is Domain Authority Used?
Domain Authority is used as a comparative tool. This means that there isn't necessarily any such thing as a 'good' or 'bad' score. Instead, your score is compared to other websites in your industry or niche.
Therefore, trying to get a high score shouldn't be your only SEO activity. Focus on beating your direct competitors rather than achieving an arbitrary number. If your competitors have DA scores of 35-45, aiming for 50+ gives you a competitive advantage.
While DA isn't a direct ranking factor, it correlates with the signals that matter to search engines. According to Google's own research on how AI powers search results, quality and authority signals play a significant role in determining which pages rank highest.
How To Boost Your Domain Authority
The best thing you can do is earn backlinks from websites that have a high DA. However, this strategy needs constant updating as the DA of the websites that link to you may fluctuate. In addition, DA is calculated based on the number of unique backlinks your website has earned. That being the case, finding one successful website to link back to you simply isn't enough.
Other things you can do are:
- •Produce high-quality and relevant content (this will naturally make people want to link to you)
- •Have a water-tight social media strategy in place (social signals indicate how useful your content is)
- •Create user-friendly and search engine friendly content (this includes layout and easy navigation)
- •Fix broken links and remove toxic backlinks that can harm your overall link profile
- •Optimize internal linking structure to distribute authority throughout your site
Step-By-Step Guide To Using The DA Checker
- Enter Your URLs: Paste up to 3 website URLs in the input field. You can enter them on separate lines or separated by commas.
- Click "Check DA": Our system queries the Moz API to fetch real-time Domain Authority and Page Authority scores.
- Review the Scores: Each domain displays DA (1-100) and PA (1-100) with color coding to help you quickly assess performance.
- Compare Competitors: Check your domain alongside 2-3 competitors to see where you stand. This reveals link building gaps and opportunities.
- Track Progress: Save your scores and recheck monthly to monitor your link building progress and DA growth over time.
10 Ways To Improve Your Domain Authority
1. Earn High-Quality Backlinks
Focus on getting links from authoritative sites in your niche. One link from a DA 70 site is worth more than ten links from DA 20 sites.
2. Create Link-Worthy Content
Publish original research, comprehensive guides, infographics, and tools that naturally attract backlinks from other websites.
3. Remove Toxic Backlinks
Use Google Search Console to identify and disavow spammy or low-quality links that can hurt your domain's authority.
4. Fix Broken Links
Regularly audit your site for 404 errors and broken links. These create poor user experience and waste link equity.
5. Optimize Internal Linking
Create a strong internal linking structure to distribute authority throughout your site and help search engines discover content.
6. Guest Post on Authority Sites
Contribute valuable guest posts to reputable blogs in your industry. This builds relationships and earns quality backlinks.
7. Build Brand Mentions
Get your brand mentioned on authoritative sites, even without links. Brand signals contribute to overall domain strength.
8. Improve Site Speed and UX
Fast, user-friendly sites retain visitors longer and earn more natural backlinks. Technical SEO matters for long-term authority growth.
9. Diversify Link Sources
Get links from various types of sites — blogs, news sites, directories, and industry resources. Link diversity signals natural growth.
10. Be Patient and Consistent
DA growth takes time. Focus on consistent, quality link building over 6-12 months rather than quick wins that might trigger penalties.
Pro Tips For Domain Authority Growth
Track Competitor DA Monthly: Use this tool to check your top 3-5 competitors every month. If they're gaining DA faster than you, analyze their backlink profiles to identify their link sources.
Focus on Link Velocity: Sudden spikes in backlinks can look unnatural. Aim for steady, consistent link growth — 5-10 quality links per month is better than 100 low-quality links at once.
Prioritize Relevance Over DA: A link from a DA 40 site in your niche is often more valuable than a DA 60 site in an unrelated industry. Relevance matters.
Don't Obsess Over the Number: DA is a prediction metric, not a goal. Focus on fundamentals — great content, technical SEO, and earning links naturally. DA will follow.

Why Domain Authority Matters
While DA isn't a direct Google ranking factor, it correlates strongly with search performance. Here's why monitoring DA is valuable:
- ✓Competitive Benchmarking: Compare your site against competitors to identify link building gaps and opportunities
- ✓Link Building ROI: Track whether your link building efforts are actually moving the needle on your domain's authority
- ✓Outreach Targeting: Identify which domains are worth pursuing for backlinks based on their DA scores
Common Domain Authority Mistakes
- ×Treating DA as a Google Metric: DA is created by Moz, not Google. It's a useful prediction tool but not an official ranking factor
- ×Buying Links to Boost DA: Purchased links often come from low-quality sites and can result in Google penalties that harm your real rankings
- ×Ignoring Page Authority: Individual pages can have high PA even if domain DA is low. Optimize both for maximum impact
- ×Panicking Over Score Drops: DA fluctuates as Moz's index updates and competitors gain links. Small decreases are normal and don't mean your rankings will drop
