What it does and why it matters.
Domain Authority (DA) and Page Authority (PA) are predictive metrics developed by Moz that estimate how likely a website or specific page is to rank in search engine results. Scores range from 1 to 100 on a logarithmic scale, meaning it is much harder to improve from 70 to 80 than from 20 to 30. Our free DA PA checker gives you instant authority scores for any domain.
How to Use This Free Domain Authority Checker
Enter any domain and this tool returns verified, first-hand facts about it: registration date and registrar from RDAP (the registry protocol that replaced WHOIS), domain age, expiry, HTTPS status, HTTP response code, the full redirect chain, whether the URL is indexable, and how its canonical tag resolves. Those are all measurable, and every one of them is checked live rather than estimated.
Domain Authority and Page Authority are not returned by default, because they cannot be. DA and PA are proprietary Moz metrics computed from Moz's own link index. No tool can derive them from a page fetch, and any free checker showing you a DA figure is either calling the Moz API or making it up. If you have Moz Links API credentials, they can be added to this site's environment and real DA, PA and Moz Spam Score will appear alongside the checks above. Otherwise, use Moz's own domain analysis for the metric itself.
What Is a Good Domain Authority Score?
DA scores are relative, not absolute, so a "good" score depends on your competitive landscape. Brand-new websites start with a DA of 1, while sites like Wikipedia (DA 99) and Google (DA 100) represent the top of the scale. For most small to medium businesses, a DA between 30 and 50 is competitive, while scores above 50 indicate strong authority. The most actionable use of DA is comparative: check your score against the top-ranking sites for your target keywords to understand the authority gap you need to close through strategic link building and content marketing.
DA, PA, and Actual Google Rankings
It is important to understand that Domain Authority and Page Authority are not Google ranking factors. They are third-party predictions created by Moz based on link profile analysis. Google uses its own internal metrics, including PageRank, which are not publicly visible. However, the signals that improve DA — high-quality backlinks, diverse referring domains, and clean spam profiles — are indeed factors Google considers. Use our Spam Score Checker to verify your domain's health, and our Meta Tag Analyzer to ensure on-page elements are optimized for the keywords you want to rank for.
I use Domain Authority as a compass, not a scoreboard. It tells me where I stand relative to competitors and helps prioritize link-building targets. But the real work is building genuine authority through great content and relationships — the DA score follows naturally.
DA PA Checker — Domain Authority & Page Authority: questions
Domain Authority scores are best evaluated in context rather than as standalone numbers. Generally, scores between 0-30 indicate a developing site that is still building its link profile, 30-50 represents average authority competitive in many local and niche markets, 50-70 indicates strong authority sufficient to compete for moderately competitive national keywords, and 70+ represents excellent authority held by major brands and well-established publishers. New websites typically start with a DA of 1 and may take 6-12 months of consistent link-building to reach DA 20-30. The most useful approach is to compare your DA against the top-ranking sites for your specific target keywords. If the top results have DA 45-55 and your site is at DA 30, you know the approximate authority gap to close through strategic backlink acquisition and content development.
Improving Domain Authority requires a sustained, multi-faceted approach because DA is calculated from over 40 link-related signals. Start by acquiring high-quality backlinks from authoritative, relevant websites through digital PR, guest posting on industry publications, creating linkable assets like original research and data studies, and building genuine relationships with journalists and bloggers. Simultaneously, audit your existing backlink profile using a tool like Moz or Ahrefs and disavow toxic or spammy links that drag down your score. Strengthen your internal linking architecture so link equity flows efficiently to your most important pages. Improve technical SEO fundamentals including site speed, mobile-friendliness, and HTTPS. DA improvement is gradual — expect to see meaningful movement over 3-6 months of consistent effort rather than overnight jumps.
No, Domain Authority is not a Google ranking factor. DA is a proprietary metric created by Moz that predicts ranking potential based on their analysis of link data. Google has confirmed through spokesperson John Mueller that they do not use any third-party authority scores in their ranking algorithms. Google uses its own internal link analysis systems, including an evolved version of the original PageRank algorithm, which are not publicly visible. However, the underlying factors that contribute to a high DA — quality backlinks from trusted domains, diverse referring domain profiles, and low spam signals — are indeed signals that Google's algorithms consider when ranking pages. Think of DA as a useful proxy that correlates with ranking ability rather than a metric Google directly measures or rewards.
