What is Domain Authority?
Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). Scores range from 1 to 100, with higher scores indicating greater ranking potential.
How DA is Calculated
DA considers multiple factors including:
- Number and quality of backlinks
- Linking root domains
- MozRank and MozTrust scores
- Overall link profile health
DA Score Ranges
- 1-20: New or small websites
- 21-40: Growing websites with some authority
- 41-60: Established websites with solid backlink profiles
- 61-80: High-authority sites
- 81-100: Industry leaders (Google, Facebook, etc.)
Important Notes
DA is not a Google ranking factor—it’s a third-party metric. Focus on building genuine, quality backlinks rather than chasing a specific DA score. Similar metrics include Ahrefs’ Domain Rating (DR) and Semrush’s Authority Score.
