Domain Authority (DA) is a scoring metric developed by Moz that predicts how likely a website is to rank in search engine results compared to its competitors. It’s calculated by combining multiple link metrics (such as the number of linking root domains and total links) into a single score ranging from 1 to 100. Higher scores correspond to a greater ability to rank.
Key Tools for Checking Domain Authority (DA)
Since DA is a proprietary metric owned by Moz, you must use their tools or other SEO platforms that offer a similar, proprietary score.
Tool | Proprietary Metric | Score Range | Optimal Use for UTDS Clients |
Moz Link Explorer | Domain Authority (DA) | 1 to 100 | The definitive source for the actual DA score. Excellent for link analysis and quality vetting. |
Ahrefs Site Explorer | Domain Rating (DR) | 1 to 100 | The industry-leading alternative to DA. Often considered highly accurate due to Ahrefs’ large link index. |
Semrush | Authority Score (AS) | 1 to 100 | A holistic score combining backlink data with organic traffic data for a comprehensive health view. |
The Checking Process
- Select Your Tool: Choose a reputable SEO tool (Moz, Ahrefs, or Semrush).
- Enter the Domain: Navigate to the tool’s main Domain Analysis or Site Explorer or Domain Overview feature.
- Input Your URL: Enter your website’s root domain (e.g., utds.io, without https:// or www).
- View the Score: The tool will instantly return the metric (e.g., DA 45, DR 52, or AS 50).
Optimal Interpretation of Your Score
The score itself is less important than how it compares to your competitors and how it trends over time.
- Low Score (1 – 30): Common for brand new sites or small, niche businesses. Focus should be on fundamental on-page SEO and securing the first few high-quality links.
- Medium Score (31-60): Achievable for established SMEs. This is the optimal competitive range. Focus on high-quality content marketing and targeted link building.
- High Score (61-90+): Typically reserved for major publications, large corporations, and global brands.
Strategic Action
- Benchmark: Check the DA / DR / AS of your top 5 organic competitors. Your goal is to meet or slightly exceed the score of the average competitor in your direct market.
- Track Trend: Monitor your score monthly. A rising score indicates your link building and content efforts are successfully increasing your site’s authority.
- Link Vetting: Use DA or DR to vet potential link opportunities. Getting a link from a site with a DA 50 is far more valuable than one from a site with a DA 15.
Crucial Distinction: Domain Authority (DA) is NOT a Google ranking factor. Google does not use this metric. It is a third-party predictor designed to help SEO professionals estimate success and compare domains. Your actual rankings are determined by Google’s proprietary algorithms.
