Domain Authority Checker
Check the authority score of any domain to evaluate its SEO strength.
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). Domain Authority scores range from 1 to 100, with higher scores corresponding to a greater ability to rank.
Comparative Metric
DA is best used as a comparative metric when doing research relative to your competitors.
Based on Backlinks
DA is calculated based on data from the Mozscape web index, including linking domains and number of total links.
Logarithmic Scale
DA is scored on a 100-point logarithmic scale. This means it's easier to grow from 20 to 30 than from 70 to 80.
How to Interpret Domain Authority Scores

| 1-20 | New or small websites with few backlinks | New blogs, local business sites, personal websites |
| 21-40 | Established sites with growing link profiles | Small business sites, niche blogs with some authority |
| 41-60 | Popular sites with strong link profiles | Industry blogs, medium-sized businesses, educational sites |
| 61-80 | Very authoritative sites with excellent link profiles | Major news publications, large businesses, government sites |
| 81-100 | The most authoritative sites on the internet | Google, Facebook, Amazon, Wikipedia, major universities |
