Domain Authority Checker

Check the Domain Authority (DA) of any website in seconds. Enter a domain and our checker returns its authority score — a 1-to-100 estimate of how strong a site is in search — so you can benchmark competitors, track your own progress, and judge a domain before you buy it. Below is a clear explanation of what the score means and, just as importantly, what it doesn't.

What is Domain Authority?

Domain Authority is a score from 1 to 100, created by Moz, that predicts how likely a website is to rank in search results. It's calculated mainly from a site's backlink profile — the number and quality of other sites linking to it. A higher score suggests stronger ranking potential. Crucially, DA is a third-party metric, not a Google ranking factor: Google doesn't use it. It's best treated as a comparative thermometer, not a number search engines actually read. For the full breakdown, see our guide on what Domain Authority is and how to improve it.

How do I check Domain Authority?

1. Enter the domain (for example, example.com) into the box above.
2. Run the check to see the Domain Authority score.
3. Compare it with competitors, or re-check your own domain over time to track the trend.

How is the score calculated?

The score is built from link-based signals, the most important being the quality and diversity of referring domains pointing to a site. Two properties are worth knowing:

• It's logarithmic — rising from 20 to 30 is much easier than 70 to 80, so growth slows at the top.
• It's relative — your score is recalculated against the rest of the web, so it can shift even when your own site hasn't changed.

What is a good Domain Authority score?

There's no universal target. A DA of 30–40 can be competitive in a small niche, while crowded industries may need 60+. The useful comparison is against the sites already ranking for your keywords: if they're around 35 and you're at 40, you're well placed regardless of the absolute number.

Does Domain Authority affect my Google rankings?

Not directly. DA often correlates with rankings because quality backlinks raise both — but the goal is earning real links and trust, not inflating a score. Don't buy links or use link schemes to chase a higher number; that risks penalties that hurt actual rankings.

How can I improve it?

• Earn high-quality backlinks from relevant, reputable sites.
• Publish content other sites want to reference, so links come naturally.
• Strengthen internal linking so authority flows through your site.
• Clean up toxic or spammy links.
• Be patient — meaningful change takes months.

Frequently asked questions

Is Domain Authority a Google metric?

No. It's a Moz score. Google doesn't use Domain Authority and has said it has no single site-wide authority number.

Why does my DA differ from another tool's score?

Each tool (Moz DA, Ahrefs DR, Semrush Authority Score) uses its own link index and formula, so numbers won't match. Track one tool's trend rather than comparing across them.

Why did my score change on its own?

DA is recalculated relative to the wider web, so it can move when other sites gain links or the index updates.

Is a low DA bad for a new site?

No. New domains start low. Focus on content and earning quality links, and the score will follow.
