What Is Domain Authority (DA)?
Domain Authority (DA) is a comparative search engine ranking metric developed by Moz that predicts a website's overall likelihood of ranking on Search Engine Results Pages (SERPs). DA scores range from 1 to 100, calculated by evaluating link equity, total referring domains, unique linking root domains, and website trust signals.

- DA 30–49 (Moderate): Growing blogs and small business websites building initial link equity.
- DA 1–29 (New/Low): Brand new domains or sites with minimal inbound links.

Frequently Asked Questions
What is Domain Authority (DA)?
Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs) on a 1-100 scale.
What is the difference between DA and PA?
Domain Authority (DA) measures the overall ranking strength of the entire domain, while Page Authority (PA) measures the strength of a specific individual URL page.
Is Domain Authority a direct Google ranking factor?
No, DA is a third-party metric created by Moz, not a direct Google algorithm factor. However, it correlates strongly with search ranking potential based on backlink profiles.
How many domains can I check at once?
You can check up to 5 website URLs simultaneously in a single bulk request.

What Is Domain Authority (DA)?
Domain Authority is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine results pages (SERPs). DA scores range from 1 to 100, with higher scores indicating greater ranking potential. The metric is calculated based on linking root domains, total backlinks, and other SEO signals. It's important to note that DA is a comparative metric — it's most useful for comparing websites against each other, not as an absolute measure.
DA PA Checker – Domain Authority vs Page Authority
Our DA PA checker measures both scores: Domain Authority (DA) evaluates the overall ranking strength of an entire domain, while Page Authority (PA) measures the ranking potential of a single specific page. For example, a blog's homepage might have DA 45, while an individual post page might have PA 32. Both metrics use Moz's machine learning algorithm trained on actual Google search results. Use DA for overall site comparisons and PA for evaluating specific landing pages or blog posts.

Our bulk domain authority checker lets you check up to 5 URLs in a single request — perfect for comparing your site against competitors, evaluating guest post opportunities, or auditing a list of link prospects. The DA checker returns DA score, PA score, spam score, total backlinks, referring domains, and IP address for each domain. Export results as JSON for further analysis in spreadsheets or SEO dashboards.
DR Checker & Domain Rating Checker
Domain Rating (DR) is Ahrefs' equivalent metric to Moz's DA, measuring the strength of a website's backlink profile on a 0–100 scale. While our tool uses the Moz-based DA/PA system, the DR checker concept is similar — both evaluate link authority. For a complete picture, check your domain with both our DA checker and Ahrefs' Website Authority Checker to compare DA and DR scores side by side. Domain rating checker results from different tools may vary because each uses proprietary algorithms and different backlink indexes.
Moz Domain Authority & Semrush Domain Authority Checker
Moz Domain Authority is the original and most widely referenced authority metric in the SEO industry. Semrush offers its own "Authority Score" metric in its Semrush domain authority checker, which combines backlink data, organic traffic, and spam signals. Our tool provides Moz-based DA/PA scores for free — giving you the same core metrics that Semrush and Moz charge for in their premium plans. Use our free checker for quick lookups and save premium tool credits for deep-dive analysis.
Spam Score Checker
Our tool includes a spam score checker that evaluates whether a domain exhibits signals commonly associated with penalized or low-quality websites. Moz's Spam Score ranges from 1% to 100% — scores above 30% indicate potential risk. High spam scores can result from spammy backlinks, thin content, or association with link schemes. Check spam scores before accepting guest posts, exchanging links, or purchasing expired domains to avoid negative SEO impacts.
How to Increase Domain Authority
How to increase domain authority is one of the most common SEO questions. DA improves gradually through consistent effort:
- Build quality backlinks: Earn editorial links from high-DA sites through guest posting, original research, and linkable content assets.
- Create comprehensive content: Publish in-depth, original content that naturally attracts links and social shares.
- Fix technical SEO: Ensure fast page speed, mobile responsiveness, proper internal linking, and clean site architecture.
- Remove toxic backlinks: Use Google's Disavow Tool to distance your site from spammy or harmful inbound links.
- Be patient: DA is a long-term metric. New domains typically start at DA 1 and build authority over months and years of consistent SEO effort.
Page Authority Checker – Individual Page Scoring
The Page Authority checker component of our tool evaluates individual page URLs rather than entire domains. PA is especially useful for evaluating specific landing pages for link-building targets, comparing blog post authority across competitor sites, and identifying your highest-authority pages for internal linking strategies. A page with high PA and relevant content makes an excellent target for outreach and guest posting partnerships.
