Question 1

What is Moz Domain Authority (DA)?

Accepted Answer

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages (SERPs). DA scores range from 1 to 100, with higher scores indicating greater ability to rank.

Question 2

How is Domain Authority calculated?

Accepted Answer

DA is calculated using multiple factors including linking root domains, number of total links, MozRank, MozTrust, and other SEO metrics. The score uses a machine learning model to predict how well a domain will rank relative to others.

Question 3

What is a good Domain Authority score?

Accepted Answer

DA is relative - it's best used to compare your site to competitors. Generally: 40-50 is average, 50-60 is good, 60-70 is very good, and 70+ is excellent. New websites typically start with a DA of 1.

Question 4

How can I improve my Domain Authority?

Accepted Answer

To improve DA: 1) Build high-quality backlinks from authoritative sites, 2) Create valuable, linkable content, 3) Improve your internal linking structure, 4) Remove toxic or spammy backlinks, and 5) Ensure technical SEO is solid. DA improves naturally as your site gains authority.

Question 5

What is Moz Spam Score?

Accepted Answer

Spam Score is a metric from 0-100% that represents the percentage of sites with similar features that Moz has found to be penalized or banned by Google. Lower scores (0-30%) are better. High spam scores may indicate problematic SEO practices.

Question 6

How often does Domain Authority update?

Accepted Answer

Moz updates Domain Authority approximately once per month. However, our tool provides real-time access to the latest available DA data, and we also show historical DA trends so you can track changes over time.

Question 7

Why did my Domain Authority drop?

Accepted Answer

DA can drop for several reasons: 1) Your competitors gained more/better backlinks, 2) You lost quality backlinks, 3) Moz updated their algorithm, or 4) Your site was affected by a Google penalty. DA is relative, so changes in the competitive landscape affect scores.

Question 8

Is Domain Authority a Google ranking factor?

Accepted Answer

No, DA is not used by Google for rankings. It's a third-party metric created by Moz to help estimate ranking potential. However, the factors that improve DA (quality backlinks, content, etc.) do influence Google rankings.
