Explaining domain authority: A beginner’s guide

Domain Authority explained

What is domain authority?

Domain authority (DA) is a metric used in SEO to measure the power (or strength) of a web domain or website. It’s calculated using an algorithm that takes into account the total number of external links pointing towards the website and indicates the probability of that website appearing in search engine rankings. This probability is the domain authority score.

What does a domain authority score measure, and why is DA important?

A domain authority score measures the strength of your domain name using a number between 1 and 100; the higher the score, the better. This score is calculated by assessing the website’s age, links, social shares, and other factors built into the algorithm. The higher your domain authority score, the more likely you are to rank high in search engine results pages when people look for your website’s keywords.

To clarify, the domain authority score definition is not the same as the Google algorithm (aka PageRank) which influences your website ranking. PageRank is a tool used by Google that assesses a site based on page links and the authority of those links, but is not as comprehensive as the domain authority score.

How is your domain authority calculated?

Each domain authority checker might be slightly different in how they calculate your site’s score, however, the main factors used to calculate your domain authority are:

  • The number of incoming links pointing to your website
  • The quality and relevancy of incoming links
  • The quality of your website’s content
  • Social signals (the sharability and popularity of your content across social media networks)
  • Your website’s SEO performance in general
