What Is Domain Authority and How Is It Calculated?

Domain Authority (DA) is a proprietary score developed by Moz that predicts how likely a website is to rank in search engine results on a scale of 1–100. It's calculated using a machine learning algorithm that considers dozens of factors, most importantly the quantity and quality of backlinks pointing to the domain.

DA is a comparative metric, not an absolute one. A DA of 40 doesn't mean your site ranks for 40% of queries — it means your site likely has more ranking potential than a DA 30 site in the same niche. Use DA to benchmark yourself against direct competitors, not against global giants like Wikipedia (DA 92) or YouTube (DA 100).

What Factors Influence Domain Authority?

  • Total linking root domains: The number of unique domains linking to you is the single biggest DA driver. 100 links from 100 different sites is far more valuable than 1,000 links from a single domain.
  • Quality of linking domains: A link from a DA 70 site contributes significantly more to your DA than 10 links from DA 10 sites.
  • Link profile diversity: Mix of dofollow/nofollow, different link types, varied anchor text, and links from different industries all signal a natural, authoritative profile.
  • Spam score: Links from low-quality, manipulated, or penalized domains can drag DA down. Disavow genuinely toxic links via Google Search Console.

How to Improve Your Domain Authority

  • Earn links from high-DA sites in your niche — quality always beats quantity for DA growth
  • Create linkable assets (studies, tools, guides) that naturally attract editorial links
  • Remove or disavow spammy backlinks that inflate your spam score
  • Fix technical SEO issues that prevent Google from fully crawling and indexing your site
  • Build a consistent link acquisition velocity — 5–20 quality links per month sustained over 6–12 months moves DA reliably

Frequently Asked Questions

What is a good Domain Authority score? +
DA is relative to your niche and competitors. A DA 30 site competing against DA 20 competitors is in great shape. A DA 30 site trying to rank against DA 70 competitors faces a significant challenge. As general benchmarks: DA 1–20 is new/low authority; DA 20–40 is developing; DA 40–60 is established; DA 60–80 is authoritative; DA 80+ is extremely powerful. Always compare your DA against the sites actually ranking for your target keywords, not against industry giants.
How long does it take to increase Domain Authority? +
DA growth is slow and non-linear. Expect 3–6 months of consistent link building before seeing meaningful DA movement. New domains typically reach DA 20–30 within 12 months of active link building (5–15 links/month). Reaching DA 40–50 typically requires 18–24+ months. DA 60+ domains have usually been building authority for several years with sustained, high-quality link acquisition. The key is consistency — stopping link building for several months can cause DA to plateau or decline.
Is Domain Authority the same as Google PageRank? +
No — DA is a third-party metric created by Moz, while PageRank is Google's internal link authority algorithm. DA correlates well with Google rankings but doesn't perfectly replicate Google's calculations, which factor in many signals beyond links (content quality, user experience, freshness, E-E-A-T). Google's publicly visible PageRank Toolbar was retired in 2016, making third-party metrics like DA and Ahrefs's DR the best available proxies for link authority.
