Domain Authority (DA) is a metric developed by Moz that predicts how well a website will rank on search engines. It is calculated using a combination of factors, including the number and quality of links pointing to a website, the age of the domain, and the overall structure and content of the website.
Domain Authority is important because it is a key factor in determining how well a website will rank on search engines. The higher a website's Domain Authority, the more likely it is to rank well for relevant keywords and phrases. This can lead to more organic traffic and ultimately more sales for the business.
