If you’ve ever wondered why some websites consistently dominate Google search results while others struggle to rank — the answer almost always comes down to authority. Search engines reward websites that have earned trust, credibility, and a strong backlink profile. And the best way to measure that authority? A Moz DA PA checker.
Our free bulk DA PA checker tool lets you instantly analyze Domain Authority (DA), Page Authority (PA), Spam Score, total backlinks, and referring domains for any website or page — and you can check thousands of URLs at the same time, with zero cost and no account required.
Whether you’re new to SEO or a seasoned professional managing multiple client campaigns, this guide will show you exactly how to get the most out of DA and PA data.
What Is Moz — And Why Do Its Metrics Matter?
Moz is one of the most established and respected companies in the SEO industry. Founded in 2004, Moz pioneered many of the concepts and tools that modern SEO professionals rely on daily. Among their most influential contributions are Domain Authority and Page Authority — two metrics that have become the de facto standard for measuring website credibility across the industry.
Unlike Google’s internal ranking signals (which are kept secret), Moz’s DA and PA are transparent, publicly accessible, and updated regularly. That transparency is what makes them so useful — you can check any website’s score, understand where you stand, and take informed action to improve.
When someone in SEO says “this site has a DA of 50” or “that page has good PA,” they’re using Moz’s framework. It’s the common language of link building, competitive analysis, and authority benchmarking worldwide.
Domain Authority vs. Page Authority: What’s the Difference?
These two metrics are often confused, but they measure fundamentally different things.
Domain Authority (DA)
Domain Authority evaluates the entire website as a whole. It considers every backlink pointing to every page across the entire domain and produces a single score from 1 to 100 reflecting that domain’s collective ranking potential.
Think of DA as a reputation score for your brand. A website that has been earning quality links for years from trusted sources will have a high DA. A brand-new website with no backlinks starts at DA 1.
DA is best used when:
- Comparing your website against competitors
- Evaluating potential link building targets
- Assessing the overall health of a domain
- Buying or selling websites
Page Authority (PA)
Page Authority narrows the focus to a single URL. It measures how much ranking power that specific page has accumulated through its own backlinks and internal link signals.
Two pages on the same DA 60 website can have drastically different PA scores — the homepage might have PA 58 while a deep product page has PA 12.
PA is best used when:
- Evaluating where a competitor’s page gets its ranking power
- Choosing which pages to build links to directly
- Prioritizing internal linking to boost underperforming pages
- Assessing the value of a specific link placement on a referring page
The golden rule: Use DA to evaluate websites. Use PA to evaluate individual pages.
Breaking Down Every Metric in Our DA PA Checker
Domain Authority (DA) — 1 to 100
Moz’s flagship metric. Higher scores mean greater ranking potential. Because the scale is logarithmic, gains become harder to achieve as you climb. Going from DA 20 to DA 40 is far easier than going from DA 60 to DA 80.
Page Authority (PA) — 1 to 100
Same scoring model as DA, applied at the page level. Tracks the specific strength of a single URL based on its unique link profile.
Spam Score — 0% to 100%
One of the most underrated metrics in SEO. Moz’s Spam Score identifies websites whose link profiles or on-site patterns resemble sites that have been flagged, penalized, or deindexed by Google.
| Spam Score | Risk Level | Recommended Action |
| 0% – 10% | Very Low | Safe to build links |
| 11% – 30% | Low | Generally safe |
| 31% – 60% | Medium | Review manually |
| 61% – 80% | High | Avoid for link building |
| 81% – 100% | Very High | Disavow if linking to you |
Spam Score is essential for link audits, toxic link identification, and protecting your site from negative SEO.
Backlinks
The total count of all inbound links pointing to the URL or domain. This number reflects raw link volume — useful for benchmarking, though not the most important metric on its own. Quality and source diversity matter far more.
Referring Domains
The count of unique domains sending at least one link to the URL. Widely considered the most important link-building metric because Google values diversity of link sources. Getting 1,000 links from one website is far less impactful than getting links from 1,000 different websites.

5 Situations Where You Need to Run a DA PA Check Right Now
1. Before Any Link Building Outreach
Never spend time crafting a guest post pitch or partnership email without first verifying the site’s DA, PA, and Spam Score. A five-second check can save you hours of wasted effort on low-quality targets.
2. Before Buying a Sponsored Post or Paid Link
Paid placements are only worth the investment if the site has genuine authority. Use our checker to verify that a site’s DA reflects real, organic backlinks — not inflated or manipulated metrics.
3. When a Competitor Suddenly Outranks You
Pull their backlink profile, run it through the bulk checker, and find out which high-DA sources are powering their rankings. Then build a strategy to earn similar links.
4. After a Google Algorithm Update Causes a Traffic Drop
A ranking drop often signals a link-related issue. Check your backlink profile for high-spam-score domains that may have triggered a manual or algorithmic penalty.
5. When Evaluating a Website Acquisition
Buying an aged domain or an established website? DA, PA, Spam Score, and referring domain counts are essential due-diligence metrics. High DA with suspicious referring domain patterns or elevated Spam Scores are major red flags.
How to Grow Your Domain Authority: Proven Strategies
Knowing your DA is just the start. Here’s what actually moves the needle:
Earn Links From High-DA Websites
The most direct way to increase DA is to earn backlinks from authoritative, relevant websites. Focus on quality over quantity — one link from a DA 70 news site is worth more than 100 links from DA 10 directories.
Effective link-earning tactics:
- Guest posting on niche-relevant blogs
- Digital PR and newsjacking
- Creating original research, surveys, or studies
- Building free tools that attract organic links
- Resource page link building
Diversify Your Referring Domains
If 80% of your backlinks come from five domains, your profile is fragile. Actively build links from a wide variety of unique domains across different industries, geographies, and content types.
Remove or Disavow Toxic Links
High Spam Score links can drag down your overall authority. Run a full backlink audit using our checker, identify toxic referring domains, and submit a disavow file to Google Search Console to neutralize their impact.
Improve Your Internal Linking Structure
Internal links distribute page authority across your site. Create strong internal link clusters connecting your most important pages to ensure link equity flows where it matters most.
Publish Content That Earns Links Naturally
Comprehensive guides, original data, and genuinely useful resources attract backlinks without any active outreach. The longer this content stays relevant, the more authority it accumulates over time.
Be Patient — DA Growth Takes Time
DA is a long-term metric. Consistent, ethical link building over months and years is what separates DA 20 sites from DA 60 sites. There are no legitimate shortcuts.
Frequently Asked Questions About DA PA Checking
Can I check my competitors’ DA and PA? Absolutely. Simply paste any domain or URL — including competitors — into the bulk checker. This is one of the most common and valuable use cases.
Does a high DA guarantee top Google rankings? No. DA is a predictive metric, not a guarantee. A site with DA 60 can be outranked by a DA 40 site if the lower-DA site has better content, stronger on-page SEO, or more relevant backlinks for a specific query.
Is Spam Score calculated by Google? No. Spam Score is a Moz metric, not a Google signal. However, it correlates strongly with sites that Google has penalized or devalued, making it a useful warning indicator.
My DA dropped — what happened? DA can drop for several reasons: Moz updated its index, competitors in your space gained more links (making your relative score lower), or you lost some backlinks. A small fluctuation is normal. A significant sustained drop warrants a backlink audit.
What’s the difference between DA and DR? DA (Domain Authority) is Moz’s metric. DR (Domain Rating) is Ahrefs’ equivalent metric. Both measure backlink-based authority on a 1–100 scale but use different data sources and algorithms. Our tool focuses on Moz’s DA and PA.
