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
