Domain Authority Checker
Have you ever wondered why some websites show up on Google's first page every single time — while others stay buried on page 10? A big piece of that puzzle is domain authority.
Whether you are a blogger, a small business owner, or an SEO specialist, knowing your domain authority score tells you a lot about how strong your website is. And with a free domain authority checker, you can find out in seconds — no signup needed.
This guide explains everything you need to know about domain authority, page authority, spam scores, and how to actually improve your site's DA over time.
What Is Domain Authority?
Domain Authority (DA) is a number between 1 and 100 that shows how powerful a website is. The higher the number, the stronger the site. It was created by Moz, one of the most trusted names in SEO.
Think of it like a school grade. A website with a DA of 90 is like an A+ student. A site with a DA of 10 is just getting started. New websites always begin with a low score, and it goes up as you build trust and earn links from other sites.
💡 Simple explanation: Domain Authority tells you how much Google is likely to "trust" a website. More trust = better chance of ranking higher in search results. It is not an official Google metric, but it is one of the most widely used SEO scores in the industry.
Domain Authority is especially useful when you want to:
-
Compare your site's strength to a competitor
-
Find good websites to get backlinks from
-
Track whether your SEO work is paying off
-
Decide if a potential guest post site is worth your time

What Do the DA Scores Mean?
DA scores are not created equal. A score of 40 might be excellent for a small niche blog, but weak for a national news website. Here is a general guide to help you understand where you stand:
| DA Score | Rating | What It Means | Typical Examples |
|---|---|---|---|
| 1–20 | Weak | New or very young website with few backlinks | Brand-new blogs, startup websites |
| 21–40 | Average | Growing site with some good links | Local business sites, small blogs |
| 41–60 | Good | Established site with solid link profile | Mid-size businesses, popular blogs |
| 61–80 | Great | Strong, trusted site in its niche | Industry leaders, major publications |
| 81–100 | Elite | Extremely authoritative global website | Wikipedia, BBC, Amazon, Google |
⚠️ Important tip: Never compare your DA score to a completely different type of website. A local florist with DA 35 is doing great — but DA 35 would be weak for a national bank. Always compare yourself to your direct competitors.
Domain Authority vs Page Authority — What's the Difference?
These two scores are often confused, but they measure different things:
🌐 Domain Authority (DA)
Measures the overall strength of your entire website. It looks at every page and every backlink your whole domain has collected.
📄 Page Authority (PA)
Measures the strength of one single page on your website. A page can have a high PA even if the rest of the site has a low DA.
Both DA and PA run on a scale from 1 to 100. Both are calculated by Moz. When you check your domain authority, you will usually see both scores together, which gives you a fuller picture of your website's performance.
How Is Domain Authority Calculated?
Moz uses a complex formula to work out your DA score. The main things it looks at are:
How many other websites link to yours. More links from more unique sites generally means a higher DA score.
A link from a high-DA site like BBC or Wikipedia is worth far more than hundreds of links from low-quality sites.
Moz counts how many unique websites (root domains) link to you. 100 links from 100 different sites beats 100 links from just one site.
Links from spammy or low-quality sites can actually hurt your DA. A clean, healthy backlink profile is key.
The DA algorithm also looks at your site's age, internal linking structure, and content quality. Because DA is a logarithmic scale, it gets harder to improve as you go up. Getting from 20 to 30 is much easier than going from 70 to 80.
How to Improve Your Domain Authority in 2026
Growing your DA does not happen overnight — but with the right steps, you can make steady progress. Here is what actually works:
1. Build Quality Backlinks
This is the biggest single factor. Reach out to other websites in your niche and ask them to link to your content. Guest posting, digital PR, broken link building, and creating shareable content (like studies, infographics, and tools) are all proven ways to earn backlinks.
2. Create Content People Actually Want to Link To
Original research, detailed how-to guides, free tools, and expert roundups naturally attract links over time. Ask yourself: would another website want to send their readers to this page?
3. Fix Technical SEO Issues
A fast, secure (HTTPS), mobile-friendly website with a clean internal link structure builds trust. Make sure your site does not have broken links, duplicate content, or slow page speeds dragging it down.
4. Remove Toxic Backlinks
Bad links from spammy websites increase your spam score and can reduce your DA. Use Google's Disavow Tool to remove links that are hurting your profile.
5. Be Patient and Consistent
DA is a long game. Keep publishing helpful content and earning links every month. Track your progress with the DA checker every few weeks to see how you are doing.
🎯 Pro tip: Before you reach out to a website for a backlink or guest post, use the domain authority checker to see their DA score first. Aim for sites with a DA higher than your own — those links will do the most good.

Frequently Asked Questions
What is Domain Authority and why does it matter?
Domain Authority (DA) is a score from 1 to 100 created by Moz. It predicts how likely your website is to rank well on Google. The higher the score, the stronger the site. It matters because it helps you understand your own SEO strength and compare yourself to competitors — so you can spot gaps and opportunities.
Is Domain Authority a Google ranking factor?
No. Google has not confirmed that it uses Domain Authority in its ranking algorithm. DA is a third-party metric made by Moz, not by Google. However, the factors that help raise your DA — like quality backlinks and strong content — are also things that do help you rank better on Google.
What is a good Domain Authority score?
There is no single "good" score for everyone. A DA of 40–50 is considered average. Scores of 50–60 are good, and anything above 60 is excellent. The key is to compare your score against the competitors in your exact niche — not random websites. If your DA is higher than your competitors, you are in a strong position.
How often does Domain Authority update?
Moz updates its Domain Authority data on a rolling basis, roughly every few weeks. That means your DA score can change as Moz recrawls the web and updates its backlink index. Improvements to your backlink profile may take a few weeks to show up in your DA score.
Can my Domain Authority go down?
Yes, it can. If competitors build more backlinks than you, your relative DA can drop even if you have not done anything wrong. DA can also fall if you lose backlinks, gain toxic links, or if Moz updates its algorithm. This is why it is important to monitor your score regularly and keep building high-quality links.
What is spam score and how does it affect DA?
Spam Score is another Moz metric that shows how many red flags your website has compared to sites that have been penalised. A high spam score means your backlink profile might contain low-quality or suspicious links. This can drag your DA down. Aim to keep your spam score below 10%. If it is higher, consider using Google's Disavow Tool to clean up bad links.
What is the difference between DA and DR?
DA (Domain Authority) is Moz's metric. DR (Domain Rating) is Ahrefs' version of the same idea. Both score from 0 to 100 and both measure the strength of a website's backlink profile. They are calculated differently, so your DA and DR scores may not match — but both are useful tools for benchmarking your SEO strength.
