Domain Authority – What is it and How to Improve it

Domain Authority is a metric created by Moz that dynamically assigns a 0 to 100 score based on how well any given domain is expected to rank on search engines. Basically, the higher your Domain Authority, the more likely your domain will rank well on Google and similar search engines.

What Does the 0 to 100 Domain Authority Score Mean?

The 0 to 100 score is based upon a logarithmic scale. This means is that it is significantly easier to improve a ranking of 10 to 20 than it will be to increase one from 50 to 60. The logarithmic Domain Authority scale was chosen on purpose to more accurately parallel how search engines assign rank and authority.

Why is Domain Authority Important

Domain authority is a signal of trust, and as a business, you should want your website and brand to be as authentic as possible. Domain Authority is not only a good measuring stick to gauge your standing in this regard, but it can also be used as a tool to make sure your website is associated with authentic sources.

How is Domain Authority Calculated?

Domain Authority is calculated by keeping track of several variables. Some of the most important variables and factors used to score your domain include:
  • Linking root domains
  • Number of total links
  • Number of inbound external links
  • Number of outbound external links
  • And more

How to Determine Your Domain Authority

Finding your Domain Authority score is quite simple. Several top-name SEO tool sand online marketing platforms dynamically track your Moz Domain Authority score. The easiest way to find your score is to simply install the MozBar SEO toolbar on your browser of choice. You can also use Link Explorer from Moz as well as their API.

Why Did Your Domain Authority Change?

Since Domain Authority is a multi-faceted and complex ranking system, determining exactly why your score has fallen can be quite a difficult task. Some of the most common reasons for a falling Domain Authority score (according to Moz themselves) include:
  • High authority sites grew their links substantially which can skew the algorithm’s scaling process
  • Inbound links to your site that do not contribute to Google and other search engine ranking algorithms (low authority sites)
  • A recent Moz crawl of your site resulted in fewer (or more) linking domains than a previous crawl
  • Moz hasn’t indexed your recent link growth
  • Your score is on the lower end of the scale, which means that smaller changes can have a greater negative impact

How to Improve Your Domain Authority Score

Again, since Domain Authority is a complex ranking system, directly impacting it in meaningful ways can be difficult. This is actually done on purpose. Moz wants their Domain Authority score to accurately depict what domains will perform well on Google and other similar search engines. Having an easy-to-influence score would take away from the legitimacy of the entire Domain Authority system. However, that does not mean that it is impossible or unwise to try and positively impact your Domain Authority score. According to Moz, the best way to improve your score is to simply improve your site’s SEO overall. Doing that and generally focusing on generating and earning high-authority links from other well-linked pages.
