Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank in search engine results. It is scored from 0 to 100, with higher being better.

It is made up of multiple factors, including the number and quality of incoming links to a site. It not only indicates the strength of a domain in terms of its ranking potential, but also helps compare the «authority» of a website with other competitors. It serves to improve your indexing.

Additionally, DA is useful for SEO strategies when evaluating which domains are worth getting links from.
