Domain Authority (DA)
A third-party score (1-100) predicting how likely a domain is to rank in search results.
Why It Matters
DA helps you evaluate competitor strength and the potential value of backlinks from other sites.
How It Works
Moz developed DA using machine learning models that analyze link profiles, linking root domains, and other factors to predict ranking ability. Higher scores indicate greater ranking potential. Google does not use DA directly.
Real-World Example
A site with DA 45 competes for keywords where most ranking pages have DA 30-50.
Common Mistakes
Treating DA as a Google ranking factor
Obsessing over DA score instead of actual rankings
