Understanding DA and PA in SEO
Domain Authority (DA) and Page Authority (PA) have become essential metrics for SEO professionals, digital marketers, and website owners. These metrics, developed by Moz, provide crucial insights into a website's potential to rank on search engines. In 2026, understanding DA and PA is more critical than ever as search engine algorithms become increasingly sophisticated.
Whether you're managing a single website or analyzing competitor strategies, knowing how to check DA and PA—and more importantly, how to improve these scores—can dramatically impact your search visibility. Many professionals use bulk DA PA checkers to monitor multiple domains and identify link-building opportunities quickly.
What is Domain Authority (DA)?
Domain Authority (DA) is a search engine ranking prediction score developed by Moz that estimates how likely a website is to rank well on search engine results pages (SERPs). The metric operates on a logarithmic scale from 1 to 100, with 100 being the highest possible score.
DA is calculated using multiple factors from MozLink, Moz's link research platform, which analyzes hundreds of millions of links across the internet. The algorithm considers:
- Linking Root Domains: The number of unique domains linking to your site
- Link Authority: The strength and quality of those linking domains
- Referring Pages: The total number of pages linking to your site
- Link Profile Distribution: How your links are distributed across categories
- Link Quality: Whether links come from trusted, established websites
What is Page Authority (PA)?
Page Authority (PA) is similar to Domain Authority but operates at the page level rather than the entire domain. It predicts how well a specific page will rank in search results based on its own link profile and characteristics.
While DA represents the overall strength of your entire domain, PA represents the ranking power of individual pages. This distinction is crucial because different pages on your website can have significantly different PA scores depending on their link profiles.
Factors affecting Page Authority include:
- Inbound Links to the Page: Direct links pointing to the specific page
- Anchor Text Quality: The text used in links pointing to the page
- Linking Domain Authority: The authority of domains linking to the page
- Link Relevance: How relevant linking pages are to your content
- Content Quality: Engagement signals and content performance metrics
DA vs PA: Key Differences Explained
| Aspect | Domain Authority (DA) | Page Authority (PA) |
|---|---|---|
| Scope | Entire website/domain | Individual page |
| Scale | 1-100 (logarithmic) | 1-100 (logarithmic) |
| Primary Factor | Overall domain link profile | Page-specific link profile |
| Usage | Assess overall site strength | Predict individual page ranking |
| Variation | Usually consistent across domain | Varies significantly between pages |
| Impact on Rankings | General ranking potential | Specific page ranking ability |
| Changes | Updates monthly with algorithm changes | Updates more frequently |
Why DA and PA Matter for SEO Rankings
Correlation with Google Rankings
While Domain Authority and Page Authority are not official Google ranking factors, extensive research has demonstrated a strong correlation between these metrics and actual search engine rankings. Websites with higher DA and PA scores tend to rank higher in Google search results.
This correlation exists because both DA/PA and Google rankings are influenced by similar underlying factors:
- Link Authority: Both value links from trustworthy, high-authority domains
- Link Volume: More quality backlinks generally improve both metrics
- Link Relevance: Contextually relevant links boost rankings and authority scores
- Brand Signals: Established brands tend to have higher DA and better rankings
- Content Quality: Better content earns more links, improving both metrics
Understanding DA and PA helps you:
- Benchmark Your Site: Compare your authority against competitors
- Identify Link Opportunities: Find high-authority sites for link building
- Predict Ranking Potential: Estimate how well new content might rank
- Make Strategic Decisions: Decide where to invest SEO resources
- Monitor Progress: Track improvements over time with bulk DA PA checkers

How to Improve Domain Authority
While DA is a difficult metric to improve quickly (it's logarithmic, meaning each point becomes harder to achieve), consistent effort on link building and content creation will gradually increase your domain authority.
Strategies to Increase Domain Authority
1. Build High-Quality Backlinks
Focus on acquiring links from relevant, high-authority websites. Quality matters far more than quantity. One link from DA 60+ website is worth more than 100 links from DA 10 websites.
- Guest post on industry-leading blogs
- Get mentioned in industry publications
- Create linkable assets (research, tools, infographics)
- Develop resource pages in your niche
- Participate in podcasts and interviews
- Sponsor relevant events and projects
2. Improve Content Quality
Better content naturally attracts more quality links and engagement:
- Create comprehensive, in-depth guides
- Publish original research and data
- Update existing content regularly
- Address trending topics in your industry
- Create content gap analysis versus competitors
3. Remove Toxic Links
Negative SEO can hurt your DA. Monitor your link profile regularly and disavow low-quality, spammy links using Google Search Console.
4. Build Referring Domains
DA is primarily based on linking root domains (unique websites linking to you). Focus on getting links from as many relevant, unique domains as possible.
How to Improve Page Authority
Page Authority is more controllable than Domain Authority because it focuses on individual pages. Here's how to improve PA for specific pages:
Strategies to Increase Page Authority
1. Build Internal Links
Link to important pages from other high-authority pages on your site. This distributes authority throughout your domain and improves specific page PA.
- Link from homepage to important pages
- Create contextual internal links in content
- Use descriptive anchor text for internal links
- Link from high-authority existing pages
- Create hub pages linking to related content
2. Get Targeted External Links
Acquire backlinks specifically pointing to the page you want to improve. This directly increases that page's PA.
- Guest post linking to that specific page
- Get citations and mentions from relevant sites
- Participate in roundup posts linking to your content
- Collaborate with influencers on content
- Reach out to sites linking to similar content
3. Optimize for User Engagement
Pages with better engagement signals tend to have higher PA:
- Reduce bounce rate with better UX
- Increase time on page with quality content
- Add multimedia (videos, images, infographics)
- Improve readability with better formatting
- Include related content links
4. Create Linkable Content
Focus on content types that naturally attract links:
- Original research and statistics
- Comprehensive guides and tutorials
- Interactive tools and calculators
- Infographics with data visualization
- Tools and resources for your industry
What's a Good DA PA Score?
| Score Range | Assessment | Context |
|---|---|---|
| 1-10 | Very Low | New websites or sites with minimal links |
| 11-20 | Low | New sites building authority slowly |
| 21-30 | Below Average | Established sites with some authority |
| 31-40 | Average | Competitive in many niches |
| 41-50 | Good | Strong authority in most niches |
| 51-60 | Very Good | Excellent authority, top ranking potential |
| 61-70 | Excellent | Exceptional authority, likely page one rankings |
| 71-100 | Outstanding | Rare, reserved for major brands and institutions |

Frequently Asked Questions
Domain Authority (DA) is Moz's metric (1-100 scale), while Domain Rating (DR) is Ahrefs' equivalent metric. Both measure similar concepts—a domain's ability to rank—but use different algorithms and data sources. They're generally comparable, with DR being considered slightly more accurate by some professionals due to Ahrefs' larger link index.
Moz updates DA and PA scores approximately monthly, though the exact schedule varies. Changes are most noticeable in bulk updates when Moz refreshes their entire link index. Individual PA scores may fluctuate more frequently as pages gain/lose links, while DA is relatively stable month-to-month.
Yes, absolutely. A site with DA 50 might have pages with PA 20 (new content) or PA 65 (well-promoted content). DA represents overall domain strength, while PA is specific to each page's link profile and performance. This is why internal linking and strategic content promotion are important.
Buying expired domains with high DA can help you get a head start, but with caution. Google has become better at detecting such tactics, and the links on those domains may be low-quality or irrelevant. Better strategy: build your own domain authority through quality content and legitimate link building. Use DA as one factor among many when evaluating domain purchases.
Higher DA/PA strongly correlates with better rankings, but it's not a guarantee. Google uses 200+ ranking factors, and your content quality, keyword relevance, user experience, and on-page SEO all play crucial roles. A medium DA site with exceptional, relevant content can outrank a higher DA site with mediocre content.
DA improvements are gradual. You might see initial increases within 2-3 months of consistent link building, but significant improvements (moving from DA 20 to DA 40) typically take 6-12 months or longer. The logarithmic scale means each point becomes progressively harder to achieve. Focus on sustainable link-building rather than quick gains.
Yes, you can lose DA/PA if you lose significant backlinks, acquire toxic links, or your site gets penalized by Google. This is why monitoring your link profile regularly with bulk DA PA checkers is important. Remove or disavow low-quality links to protect your authority scores.
There's no minimum DA to rank in Google—new websites with DA 0 can rank for relevant keywords. However, higher DA gives you a significant advantage, especially for competitive terms. In highly competitive niches, DA 30+ typically performs better than DA 10 sites, but content quality can overcome low DA advantages.
Conclusion:
Domain Authority and Page Authority remain crucial metrics for understanding your website's ranking potential in 2026. Whether you're a solo blogger, digital marketer, or enterprise SEO professional, understanding these metrics and leveraging bulk DA PA checkers to monitor progress is essential.
Key Takeaways:
- ✅ DA measures overall domain ranking potential; PA measures individual page ranking ability
