How Domain Authority is Calculated

Domain Authority (DA) is a metric that predicts how well a website will rank on search engines. Our calculator uses these proven factors:

  • Domain Age: Older domains (5+ years) have more trust and authority
  • Domain Length: Shorter domains (under 15 characters) are more valuable
  • Keywords in Domain: Domains containing relevant keywords rank better
  • TLD Quality: .com, .org, .io are more authoritative than .xyz, .info
  • Backlinks Estimate: More referring domains = higher authority
  • Social Signals: Presence on social platforms boosts authority
