Free Domain Authority Checker — Check DA, PA & SEO Metrics Instantly

Before you pitch a guest post, evaluate a potential link building target, research a competitor, or decide where to invest your SEO efforts, you need to know one thing — how strong is that website? Domain Authority gives you the answer. It is a score that tells you, at a glance, how likely a website is to rank well in search engines based on the quality and quantity of links pointing to it. Our Free Domain Authority Checker lets you check this score for any website in seconds — along with Page Authority, referring domains, and other key SEO metrics — without paying for an expensive subscription or creating an account.

You can check a single URL or use our bulk check feature to analyze up to five URLs at the same time. Fast, free, and completely private — no data is ever stored.

What Is This Free Domain Authority Checker?

This is an online SEO tool that analyzes any website URL you enter and returns a full set of authority metrics instantly. It checks the domain-level authority of the website as a whole, the page-level authority of the specific URL you enter, and the number of referring domains pointing to the site.

When you run a check, the tool gives you:

• Domain Authority (DA) score — the overall strength of the entire domain on a scale of 1 to 100
• Page Authority (PA) score — the ranking potential of the specific page URL on a scale of 1 to 100
• Referring Domains count — the number of unique websites linking to the domain
• A full Authority Analysis Report with detailed metric breakdowns
• Bulk check support — check up to 5 different URLs in a single run
• Export CSV — download your results for reporting or comparison
• Copy Results — copy your findings directly to your clipboard

The tool also includes a clear DA score guide so you can immediately interpret whether a score is excellent, good, average, or poor — without needing any prior SEO knowledge.

What Is Domain Authority?

Domain Authority, commonly abbreviated as DA, is a metric that was originally developed by Moz to predict how well a website is likely to rank in search engine results pages. It is calculated on a logarithmic scale from 1 to 100, where higher scores indicate stronger, more authoritative websites.

The score is built primarily around the backlink profile of a website — the number and quality of other websites that link to it. A website that has earned many high-quality backlinks from respected, relevant sources will have a higher DA than a website with few links or links from low-quality sources.

It is important to understand that Domain Authority is not an official Google metric. Google does not use DA as a direct ranking factor. However, DA is widely used across the SEO industry as a practical benchmark for comparing website strength, evaluating link building prospects, and tracking the growth of a domain’s authority over time.

Think of DA as a useful reference point rather than an absolute truth. A website with a DA of 60 will generally rank more easily for competitive keywords than a website with a DA of 20 — not because Google reads the DA score, but because the things that contribute to a high DA score (strong backlinks, consistent content, good site structure) are also exactly what Google rewards with higher rankings.

What Is Page Authority?

Page Authority, or PA, works on the same scale as Domain Authority — 1 to 100 — but instead of measuring the strength of an entire domain, it measures the ranking potential of a single specific page.

For example, a website might have a Domain Authority of 55, but a particularly well-linked blog post on that site could have a Page Authority of 70, while a newer page with fewer backlinks might have a PA of only 25.

Page Authority is useful when you want to:

• Evaluate how competitive a specific piece of content is before trying to outrank it
• Compare the strength of individual landing pages, blog posts, or product pages
• Understand which pages on your own website carry the most authority — and use that insight to improve your internal linking strategy
• Assess the value of a specific page as a potential link building target

Both DA and PA update over time as a website earns new backlinks, loses old ones, or makes changes to its content and structure.

What Are Referring Domains?

Referring domains is the count of unique websites that have at least one link pointing to the domain you are checking. This is different from total backlinks — a single referring domain might link to your site fifty times, but it still counts as just one referring domain.

Referring domains is widely considered a more meaningful metric than raw backlink count because it measures the breadth of your link profile. A website linked to by 500 different unique domains has a much more natural and diverse link profile than a website with 5,000 backlinks all coming from the same two or three sources.

Here is a simple example:

Scenario	Total Backlinks	Referring Domains	Which Is Better?
Website A	500 links	450 unique domains	✅ Website A — broad, diverse profile
Website B	5,000 links	8 unique domains	❌ Website B — concentrated, suspicious

Search engines value link diversity. A large number of referring domains from varied, relevant websites signals genuine credibility and broad recognition across the web.

Understanding DA and PA Scores — The Complete Guide

When you get your results, here is exactly how to interpret each score range:

Domain Authority Score Guide

DA Score	Authority Level	What It Means
90 – 100	Exceptional	Global leaders — Wikipedia, YouTube, major news networks
70 – 89	Excellent	Established industry authorities with large link profiles
50 – 69	Good	Solid, well-established websites performing well in their niche
30 – 49	Average	Decent sites with room to grow — typical for many blogs and SMBs
10 – 29	Below Average	New or lightly linked websites still building their presence
1 – 9	Poor	Very new websites or sites with almost no backlink profile

Page Authority Score Guide

PA Score	Authority Level	What It Means
70 – 100	Exceptional	Highly linked, extremely competitive pages
50 – 69	Strong	Well-established pages with solid link profiles
30 – 49	Moderate	Decent page authority — competitive in many niches
10 – 29	Low	Newer pages or pages with limited backlinks
1 – 9	Very Low	New pages with little to no linking

Important Context for Reading These Scores

Domain Authority is relative, not absolute. A DA of 30 is not “bad” — it simply means there is room to grow. What matters more than the raw score is how your DA compares to the other websites ranking for your target keywords. If your top competitors have DA scores of 25 to 35 and you are at 30, you are well-positioned to compete. If your competitors are at DA 70 and you are at 15, you have significant work to do.

How Domain Authority Is Calculated

Domain Authority is calculated using a machine learning model that analyses multiple factors related to a website’s backlink profile. While the exact formula is proprietary, the core factors that drive a higher DA score include:

Linking Root Domains The number of unique websites that link to your domain is one of the strongest drivers of Domain Authority. More unique referring domains generally means a higher DA — but quality matters more than quantity.

Quality of Linking Domains A link from a website with a DA of 80 contributes far more to your DA than a link from a website with a DA of 10. The authority of the websites linking to you directly influences your own authority score.

Link Relevance Links from websites in topics related to your own niche carry more weight than links from completely unrelated websites. A food blog linking to another food website is a more relevant signal than a tech website linking to the same food blog.

Total Number of Backlinks While unique referring domains are more important, the total number of backlinks also plays a role — particularly when those links come from many pages across multiple high-quality domains.

Spam Score of Linking Domains Low-quality, spammy websites linking to your domain can actually work against you. A clean link profile with no toxic links scores better than one filled with links from questionable sources.

Internal Site Structure and Technical SEO While backlinks are the primary driver, factors like site speed, mobile friendliness, HTTPS security, and proper site structure also contribute to how well a website performs — which over time is reflected in its ability to earn more and better links.

Why Domain Authority Matters for Your SEO Strategy

Understanding Domain Authority helps you make smarter decisions in every area of your SEO work. Here is exactly where it fits into your strategy:

Evaluating Link Building Prospects Before spending time reaching out to a website for a guest post or link placement, check its DA. A link from a website with DA 50+ will have significantly more SEO impact than a link from a DA 10 site. Use this tool to prioritize your outreach and focus your energy on the highest-value opportunities.

Competitive Analysis Enter your main competitors’ URLs into the bulk checker and compare their DA, PA, and referring domains against your own site. This tells you how much authority you need to build to compete effectively for your target keywords.

Setting Realistic SEO Goals If you know your current DA is 18 and the top-ranking pages for your target keywords have DA scores of 40 to 60, you have a clear benchmark to work toward. Tracking your DA growth over time shows you that your link building efforts are working — even before you see rankings improve.

Qualifying Guest Post Opportunities If someone offers you a guest post opportunity or approaches you with a link partnership, check their DA before agreeing. Most SEO professionals target sites with a DA of at least 20 to 30 for link building, and avoid sites with very low DA or high spam scores.

Monitoring Your Own Domain Growth Run a DA check on your own domain every month and track the score over time. A steadily increasing DA score is a strong signal that your link building strategy is working and your domain is building genuine authority in your niche.

Evaluating Acquisition Targets If you are considering buying an existing website or domain, DA is one of the first things to check. A domain with a high DA has an established backlink profile that can give a head start in rankings — though always verify the quality of the links and not just the score.

Assessing Sponsor and Partnership Value If you are evaluating whether to sponsor a website, run an ad, or partner with a media outlet, their DA gives you a quick signal of their overall online authority and search visibility.

Domain Authority vs. Google’s Ranking Algorithm — What Is the Difference?

This is one of the most common questions about DA, and it deserves a clear, honest answer.

Google does not use Domain Authority as a ranking factor. DA is a third-party metric created by Moz, not Google. Google has its own internal systems for evaluating website authority and link quality — including PageRank, which is not publicly available in its current form.

However, there is a very strong correlation between high DA scores and high Google rankings — not because Google reads DA, but because both are driven by the same underlying factors. Websites with strong, diverse backlink profiles from high-quality sources tend to both rank well on Google AND have high DA scores, because both systems are fundamentally rewarding the same thing: genuine authority earned through quality content and trusted links.

So while you should never treat DA as a direct Google ranking factor, monitoring and growing your DA is still a worthwhile practice because the actions that increase DA — earning quality backlinks, producing valuable content, maintaining strong technical SEO — are exactly the actions that also improve your Google rankings.

Metric	Created By	Used By Google?	What It Measures
Domain Authority (DA)	Moz	❌ No	Predicted ranking potential based on backlinks
Page Authority (PA)	Moz	❌ No	Predicted ranking potential for a single page
PageRank	Google	✅ Yes (internal)	Link-based authority — not publicly shared
Domain Rating (DR)	Ahrefs	❌ No	Similar to DA — based on Ahrefs’ own backlink data
Authority Score	Semrush	❌ No	Similar metric — based on Semrush’s own data

How to Improve Your Domain Authority

If your DA score is lower than you would like, here are the most effective ways to improve it over time. There are no shortcuts — DA grows through consistent, genuine effort:

Earn High-Quality Backlinks This is the single most impactful thing you can do. Focus on earning links from websites with high DA scores in niches related to yours. Guest posting, digital PR, broken link building, and creating genuinely shareable content are all proven methods.

Remove or Disavow Toxic Links If your backlink profile contains links from spammy, irrelevant, or low-quality websites, they can drag your DA down. Use Google Search Console to identify suspicious links and, if necessary, use Google’s Disavow tool to tell Google to ignore them.

Increase the Number of Referring Domains Focus your link building on earning links from many different unique domains rather than multiple links from the same few websites. Diversity in your referring domains is a key driver of DA growth.

Create Link-Worthy Content The best way to earn backlinks naturally is to publish content that other websites genuinely want to reference. Original research, comprehensive guides, free tools, infographics, and data-driven articles all tend to attract natural links over time.

Improve Your Technical SEO While backlinks are the primary driver, a technically healthy website is easier for search engines to crawl, index, and rank — which over time supports the conditions needed to earn more and better links. Focus on site speed, mobile usability, HTTPS, clean URL structure, and proper internal linking.

Be Consistent and Patient Domain Authority does not change overnight. It is a long-term metric that reflects the cumulative result of your SEO efforts over months and years. Track it monthly and look for steady upward movement rather than dramatic short-term jumps.

Frequently Asked Questions

Q: Is this domain authority checker completely free? Yes — 100% free with no account required, no subscription, and no usage limits. Check as many domains as you need without paying anything.

Q: Can I check more than one URL at a time? Yes. The Bulk Check feature lets you enter up to 5 URLs at once and compare their DA, PA, and referring domains in a single report.

Q: Is Domain Authority the same as Google PageRank? No. Domain Authority is a third-party metric created by Moz. Google PageRank is Google’s own internal link-based authority system, which is no longer publicly displayed and works differently from DA. However, both are based on the quality and quantity of backlinks pointing to a website.

Q: What is a good Domain Authority score? It depends on your niche and competitors. A DA of 30 to 50 is solid for most small to medium businesses and blogs. A DA of 50 to 70 is strong. DA above 70 is excellent and typical of large, well-established websites. What matters most is how your DA compares to the sites you are trying to outrank.

Q: How often does Domain Authority update? DA scores are recalculated periodically as the tool’s index updates and new backlink data is processed. Changes in your backlink profile — earning new links or losing old ones — will be reflected in your DA score over time, though not instantly.

Q: Why is my DA score different on different tools? Different SEO tools calculate their own version of domain authority using their own backlink databases and algorithms. Moz’s official DA, Ahrefs’ Domain Rating (DR), and Semrush’s Authority Score all measure similar things but use different data and formulas, so scores will vary between platforms.

Q: My DA dropped — what happened? DA can decrease when you lose backlinks, when competing websites gain more links than you, when the scoring algorithm updates, or when new spam links appear in your profile. A small drop is normal during algorithm recalibrations. A large sudden drop warrants a review of your backlink profile for lost or toxic links.

Q: Can I check my competitor’s Domain Authority? Yes. Enter any publicly accessible domain into the tool and it will return that domain’s DA, PA, and referring domains. This is especially useful for competitive analysis and link building prospecting.

Q: Does a high DA guarantee first-page Google rankings? No. Domain Authority is a predictive metric, not a guarantee. A high DA means your website is generally well-positioned to rank — but actual rankings depend on many additional factors including content quality, keyword targeting, on-page SEO, user experience, and the specific competition for each search query.

Q: Is my data stored after I check a domain? No. The tool processes your request and returns results without storing any data on any server. Your searches and results are completely private.
