What is Domain Authority? A Brief Explanation

What is Domain Authority

Domain Authority (DA) is used by some businesses and brands to research and evaluate the outcomes of their digital strategies.

But what exactly does this metric mean? Should we really strive to make it better? Will a high DA assist us in ranking higher on Google?

SEO specialists use domain authority (also known as site authority and website authority) to determine how “rankable” a website is as a whole.

It is based on the premise that some websites are more likely than others to rank in search engines. Most site authority scales range from 1 to 100, with higher scores indicating that the website is more likely to rank for any given term.
