Domain Authority
Domain Authority is a non-Google score created by SEO tools to estimate the comparative ranking strength of a domain.
Quick Answer
Domain Authority, often shortened to DA, is a third-party SEO metric designed to estimate how strong a domain might be compared with others. It can be useful for competitive comparison, but it is not a Google ranking factor and should not be treated as a goal by itself.
Key Takeaways
- DA is a tool metric, not a Google metric.
- It is best used for rough comparison, not strategy on its own.
- Real rankings and business outcomes matter more than a single score.

Domain Authority is a shorthand metric many SEO teams use when comparing sites, especially during backlink research or competitive review.
What It Means
It is a score created by third-party software, not by Google. The metric tries to estimate how likely a domain is to perform well in search relative to others.
Why It Matters
It can be useful for prioritizing prospects or comparing competitors quickly, but it should stay in context. A site with lower DA can still outrank a stronger domain on the right topic if content, relevance, and intent alignment are better.
Example In Practice
When reviewing outreach opportunities, DA may help sort candidates, but it should be checked alongside topical fit and editorial quality.
What It Is Not
It is not a ranking factor, and it is not proof that a domain is worth a link.
