What is Domain Authority (DA)?
Domain Authority (DA) is a search engine ranking score developed by Moz. The DA index is a number from 1-100 that predicts the ability of a website to rank on search engines. The higher the DA, the more likely the website will appear higher in search results. DA measures the strength of the entire domain, not individual pages. Factors that influence DA include: total number of backlinks, quality of backlinks, number of referring domains, domain age, and more. Jeenam will give an example of DA index: 0-20: very low, 20-40: low, 40-60: average, 60-80: good, 80-100: very high.
To help you better understand DA, we’ll compare it to two similar metrics:
| Index | Tool | Calculation Method | Advantages | Disadvantages |
| Domain Authority (DA) | Moz | Based on a machine learning algorithm, considering many factors such as backlinks and referring domains. | Measures the overall site authority, widely used. | Can be affected by changes in Moz’s algorithm. |
| Domain Rating (DR) | Ahrefs | Based on the quantity and quality of backlinks. | Strongly evaluates the backlink profile. | Does not consider other factors besides backlinks. |
| Authority Score (AS) | Semrush | Combines multiple factors such as backlinks, organic traffic, and social signals. | Provides a more comprehensive assessment of website trustworthiness, including user interaction. | More difficult to understand the calculation method compared to DA and DR. |
Why is DA Index Important?
High DA typically correlates with better search rankings. A study by Ahrefs shows there is a correlation between DA and search rankings. Although Google does not officially use DA as a ranking factor, DA provides an overview of the content relevance and quality of a website’s backlinks. DA also helps you compare your website against your competitors your competitors through competitive analysis. Finally, tracking DA over time helps you assess the effectiveness of your SEO strategies.
