Domain Authority (DA) and Page Authority (PA) remain critical metrics for evaluating the strength and credibility of websites in search engine rankings. Developed by Moz, these metrics predict how well a site or page will rank on search engine result pages (SERPs). While they are not direct ranking factors used by Google, they serve as strong indicators of a site’s potential performance.
DA is a logarithmic score (on a 100-point scale) that predicts a domain’s ability to rank across the entire web. PA, similarly scored on a 100-point scale, measures the ranking potential of a single webpage. Both scores are derived from Moz’s machine learning model, which analyzes link profiles, linking root domains, and dozens of other factors.
In 2026, the relevance of DA and PA persists due to their correlation with high-quality backlink profiles and authoritative content. However, their absolute values are less important than the trends and competitive comparisons they reveal.
Despite changes in Google’s algorithm, DA and PA remain valuable tools for SEO professionals, content strategists, and digital marketers. Here’s why:
In 2026, the rise of AI-generated content and spammy backlinks has made the quality signals behind DA/PA even more critical. Moz continues to refine its model, incorporating spam detection, topical relevance, and real-time link data to improve accuracy.
Moz updates its DA and PA scores approximately every 30–45 days. The calculation relies on a machine learning model that evaluates multiple factors:
In 2026, Moz has also introduced Real-Time DA, a beta feature that updates scores within 24 hours of significant backlink changes. This helps SEO teams respond quickly to new link acquisitions or penalties.
Example: To check the DA of
example.com, go to moz.com/link-explorer, enter the domain, and view the DA score.
Benchmark your site against competitors to identify gaps. For example:
Site A: DA 58, PA 42 (Homepage)
Site B: DA 45, PA 38
Site C: DA 72, PA 55
If your DA is 35, you’re significantly behind Site C. This signals a need for aggressive link-building or content strategy adjustments.
Track the PA of your top-performing pages (e.g., blog posts, service pages). Use MozBar to check scores during content audits. If a high-traffic page’s PA drops, investigate:
Use Moz Pro’s Rank Tracker or Link Explorer alerts to get notified when:
DA and PA scores are relative, not absolute. Use these benchmarks as general guidelines:
| Score Range | Domain Authority (DA) | Page Authority (PA) | Interpretation |
|---|---|---|---|
| 0–20 | Very Low | Very Low | New site, weak backlink profile, or penalized. |
| 21–40 | Low | Low | Established but not competitive; needs improvement. |
| 41–60 | Moderate | Moderate | Competitive in niche; solid foundation. |
| 61–80 | High | High | Industry leader; strong backlink profile. |
| 81–100 | Very High | Very High | Rare; typically reserved for top-tier brands (e.g., Wikipedia, Google). |
💡 Note: A DA of 50 doesn’t mean your site will outrank a DA 60 site in all cases. Google uses over 200 ranking factors, including relevance, user intent, and content quality.
Focus on earning links from authoritative, relevant sites. Avoid shortcuts like PBNs or paid link schemes—Moz’s spam detection is increasingly accurate.
Tactics:
Example: A SaaS company publishes a 2026 industry report on AI adoption. Sites like HubSpot and TechCrunch cite it, earning backlinks and boosting DA.
Strong internal linking distributes link equity across your site, boosting PA for key pages.
How to do it:
Example: If your homepage (PA 50) links to your "SEO tools" page (PA 25), the latter’s score will improve over time.
Content remains king. Focus on depth, originality, and utility.
Content Types That Attract Links:
📌 Tip: Use tools like Ahrefs or SEMrush to analyze which content types earn the most backlinks in your niche.
Low-quality or spammy backlinks can hurt your DA. In 2026, Moz’s spam detection is aggressive, so manual cleanup is essential.
How to identify and remove toxic links:
Example: A site with 1,000 backlinks from irrelevant blogs (DA 5–10) may see a DA drop. Disavowing these links can restore authority.
A well-organized site improves crawlability and user engagement—both indirectly linked to DA/PA.
Optimization Tips:
example.com/blog/seo-tools-2026❌ Chasing High-DA Sites Randomly: Prioritize relevance over DA. A link from a DA 50 site in your niche is better than one from a DA 80 site in an unrelated industry.
❌ Ignoring Nofollow Links: While dofollow links are more valuable, nofollow links from high-authority sites (e.g., Forbes, Wikipedia) still contribute to brand visibility and traffic.
❌ Over-Optimizing Anchor Text: Using exact-match keywords in every backlink looks unnatural. Vary anchor text with branded, natural, and partial-match phrases.
❌ Neglecting Local SEO: For local businesses, DA is less critical than Google Business Profile optimization. Focus on local citations and reviews.
❌ Assuming DA = Rankings: High DA doesn’t guarantee top rankings. Content relevance, keyword intent, and user experience play larger roles.
Competitive analysis using DA/PA helps you identify opportunities and threats.
Identify Your Top 3–5 Competitors Use tools like Ahrefs or SEMrush to find sites ranking for your target keywords.
Compare DA/PA Scores Example:
| Competitor | DA | PA (Homepage) | PA (Top Blog Post) |
|---|---|---|---|
| Competitor A | 70 | 55 | 48 |
| Competitor B | 55 | 42 | 35 |
| You | 40 | 32 | 25 |
You’re behind in all metrics. Focus on link-building and content upgrades.
Analyze Backlink Profiles Use Moz Link Explorer to see:
Example: REI’s blog ranks for "best hiking boots" with a PA of 55, driving organic traffic.
Example: A SaaS company offering a "DA Checker" tool earns backlinks from tech blogs and forums.
| Tool | Purpose | 2026 Features |
|---|---|---|
| Moz Pro | DA/PA tracking, backlink analysis | Real-Time DA, spam detection, AI-powered insights |
| Ahrefs | Backlink analysis, keyword research | Updated spam score, broken link checker |
| SEMrush | Competitive analysis, content audits | Authority Score (similar to DA/PA) |
| Majestic | Historical backlink data | Flow Metrics (Trust Flow, Citation Flow) |
| Google Search Console | Core Web Vitals, indexing | Directly tied to ranking potential |
| Screaming Frog | Site audits | Identifies broken links, duplicate content |
🔧 Pro Tip: Combine Moz with Ahrefs for a full picture. Moz for DA/PA, Ahrefs for backlink velocity and keyword gaps.
Moz continues to evolve its algorithm. Key trends to watch:
Yes, but its importance lies in trend analysis and competitive benchmarking—not absolute scores. Focus on improvement over time.
Possible with aggressive link-building and high-quality content, but rare. Most new sites stay below DA 20 in the first year.
No. Google has stated it does not use third-party metrics like DA or PA. They are predictive tools, not ranking factors.
Monthly checks are sufficient for most sites. For active SEO campaigns, weekly monitoring of key pages is recommended.
Yes. By acquiring links to a specific page (e.g., a blog post), you can boost its PA independently of the domain’s overall DA.
DA 30–50 is strong for local businesses. Focus on local citations, Google Business Profile, and niche-specific backlinks.
In 2026, DA and PA remain essential tools for gauging a website’s authority and competitive standing—but they are not the end goal. SEO success hinges on a holistic strategy that combines technical excellence, high-quality content, and ethical link-building.
Use DA and PA to:
Remember: A high DA won’t rank your site for irrelevant keywords. Pair authority metrics with keyword research, user intent alignment, and exceptional user experience. As Google’s algorithms grow more sophisticated, the sites that thrive will be those built on genuine value—not just high scores.
Start auditing your DA and PA today. Set clear goals. Build relationships, not just links. And always keep the user first. That’s the foundation of lasting SEO success.
