Domain Authority Checker

What Is Domain Authority?

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). The score ranges from 1 to 100, with higher scores indicating stronger ranking potential.

DA is calculated based on multiple factors, including the number and quality of backlinks pointing to your domain, linking root domains, MozRank, MozTrust, and dozens of other signals. It uses a machine learning model that correlates these factors with actual search engine rankings.

DA is not a Google ranking factor — it is a predictive metric created by a third party. However, because it correlates with many of the same signals Google considers, it is a valuable benchmark for comparing websites and tracking SEO progress over time.

How to Use This Tool

1. Enter the full URL of the website you want to check (e.g., example.com)
2. Click the Check button
3. View your Domain Authority score along with additional metrics

For the best results, check your own website first, then check 5-10 of your direct competitors. You can also use our DA PA Checker to check both Domain Authority and Page Authority simultaneously, or our Backlink Checker to understand the link profile behind your DA score.

Understanding Your DA Score

DA 1-20: New or very small websites with few backlinks. Normal for recently launched sites.

DA 21-40: Growing websites with a developing backlink profile. Many small businesses fall here.

DA 41-60: Well-established sites with strong backlink profiles.

DA 61-80: Highly authoritative websites. Major brands and publications.

DA 81-100: The most authoritative domains on the internet.

Remember: DA is on a logarithmic scale. Moving from 20 to 30 is much easier than moving from 70 to 80.
