In this article, we will discuss what domain authority is and how it works in brief detail. So, keep reading!

What is domain authority?

Domain Authority is a useful SEO metric designed by Moz to predict how well your website performs in search engine results. It is determined on a logarithmic scale range from 0-100. Score 1 is where all new websites start and move up to 100. 

According to the nature of this logarithmic scale, it will become more difficult once your website starts ranking higher in search results. On the other hand, jumping to a higher domain authority score is easy if you start from scratch. In general, increasing the score from 20 to 30 is easier compared to 70 to 80. 

We know most of the readers will have a question in their minds: “Is domain authority really important?” let us explain

Yes! It is important because it gives you an idea of how good your website’s performance is in search engines. Domain authority helps website owners to better understand their site’s credibility in the eye of a search engine (Google). Not just this, it also allows them to compare their website with competitors. By keeping track of competitors, website owners can fine-tune their strategy.

To better understand the importance of domain authority, we have provided an example below. 

A quality backlink from a high-authority website is more valuable in the eye of the search engine as compared to a backlink from a site with low authority. 

How domain authority works or calculated?

Domain authority is calculated by looking at numerous factors, including linking root domains, content quality, and SEO. According to Moz, overall SEO performance and backlinks positively impact domain authority. 

Let’s take a look at all these key factors:

Linking root domains: It is the number of unique backlinks that your website has. But remember, multiple links from the same website will be only counted as one linking root domain. Suppose a particular page of our website receives numerous links from a high-authority website. In that case, that page will score well in search results and improve your website’s overall score. 

Quality Content: As we all know, content is considered the king in the online industry. The quality of content on your website can increase or decrease the domain authority score. 

Moz Rank: It is a metric that allows users to determine the overall link popularity of a website in the form of a number. 

Moz Trust: Moz trust is also a notable ranking metric that measures the quantity and quality of websites linking to your website. Links from high-authority sites will result in an increased MozTrust Rating

SEO Friendliness: SEO friendliness is another crucial factor in calculating domain authority. If your website is SEO optimized, it will result in a high score and performance and vice versa.
