What is domain authority?
Domain authority (DA) is a search engine ranking score developed by Moz that predicts a website's likelihood of ranking in search engine result pages (SERPs). DA scores range from one to 100, with higher scores corresponding to a greater likelihood of ranking. DA is calculated by evaluating multiple factors, including linking root domains, the number of total links, and MozRank. MozRank is a metric developed by Moz that measures the strength of a website's link profile.
It's important to note that DA is not a metric used by Google or other search engines. Instead, it's a third-party metric that can help SEO professionals and website owners understand how their site performs regarding its backlink profile.
How is domain authority calculated?
Domain Authority is calculated by evaluating dozens of factors. Moz's algorithm uses machine learning to find the "link juice" of a given page and then applies this to the domain as a whole. Moz uses a logarithmic scale to calculate DA, which means improving your score from 20 to 30 is much easier than from 70 to 80.
What influences your domain authority score?
Many factors can influence your domain authority score, but the most important is the quality and quantity of your website's backlinks. Backlinks are links from other websites to your website. When a high-quality website links to your website, it's like a vote of confidence. This tells search engines that your website is trustworthy and authoritative.
