What is domain authority?

Domain authority is a metric that predicts how well a website will rank on search engines. It is calculated based on various factors, including the number of backlinks, the quality of those links, and other elements that contribute to a site's overall credibility and trustworthiness in the eyes of search engines.

This metric is particularly useful for SEO professionals and marketers, as it provides insight into a website's potential performance compared to competitors. A higher domain authority score suggests that a website is more likely to achieve better rankings in search engine results pages, which can lead to increased traffic and visibility.

Other options, while related to website performance, do not accurately define domain authority. For instance, measuring website traffic focuses on the actual number of visitors and their behavior, which does not directly correlate with the potential ranking ability of a site. Similarly, a score for website loading times pertains to site speed and user experience, and keyword optimization deals with how effectively a website uses specific keywords to rank. Each of these aspects plays a role in a website's overall SEO strategy but does not encapsulate what domain authority is.
