What is Domain Authority? Understanding Its Importance and Impact

In the constantly changing world of internet marketing, there is one term that has emerged as a major trend-setter and that is ‘Domain Authority’. But what is domain authority in the first place and why is it such a big deal? This article from 1Byte is intended to explain what this concept is, supported by the recent data and facts, and show how it works with examples.

Domain Authority or DA is a search engine ranking score that was created by Moz. It estimates the probability that a website will appear on the SERPs. The score varies between one and 100, and the higher the score the higher the probability of ranking. For example, a website such as Wikipedia, which is highly probable to appear in the first search results, has a DA of 77.

DA is based on Moz’s top web index and includes dozens of factors in its computation. Other SEO leaders have also created their own DA scores such as Semrush.

The domain authority scores are usually associated with higher search engine ranking. For instance, when a website has a DA score of 92, then the website pages will rank higher than a website with a DA of 65. Hence, an increase in the number of high-quality backlinks from various referring domains is associated with an increase in Domain Authority ratings.

Stay tuned for a deeper look at domain authority, how it is determined, and how you can enhance it in order to rank higher than your competitors and be more visible to potential customers.

Understanding Domain Authority

When it comes to SEO, there is one term that is quite significant and this is the term “Domain Authority”. But what is this Domain Authority? It is a score created by Moz that estimates the chances of a site’s ranking on the SERPs. This score is from one to 100 and the higher the score the higher the likelihood of ranking.

In 2019, the Domain Authority score of a domain is derived from the machine learning algorithm that predicts the frequency of Google’s use of the domain in the search results. This metric is requested over 1,000,000,000 times per year and is mentioned millions of times on the web. It has made its way to being a household name for any SEO specialist for almost any purpose, including evaluating the effectiveness of link building to qualifying domains for purchase.

Tune in as we explore more on what is domain authority, how it is determined, and how you can enhance your domain authority to rank higher than your competitors so that you can be visible to the potential customers.

What is Domain Authority?

Domain Authority or DA is a ranking metric invented by Moz that estimates the probability of a given site to rank in the SERP. It is a metric that provides you with the background information of the strength, usefulness, and pertinence of the website.

DA scores vary from one to 100 and the higher the score, the higher the chances of ranking. For example, a site with a high possibility of ranking on the first page of search engines like Wikipedia has a domain authority of 77.

How it is calculated

The DA score is obtained by assessing several parameters such as linking root domains and the total linking. It employs a machine learning model to prescriptively identify an algorithm that best matches link data to ranking on thousands of real search results.

Understanding Domain Authority

Domain Authority is not a direct metric of the ranking, and it has no relation to the SERPs, especially Google SERPs. Nevertheless, the strategies applied to increase domain authority can help in SEO.

As of the Domain Authority 2.0 update in early 2019, the calculation of a domain’s DA score is based on a machine learning algorithm’s prediction of how frequently Google is using the domain in search results.

For instance, if domain A has a higher tendency of ranking in Google SERP as compared to domain B, then the DA of domain A should be higher than that of domain B. This makes DA a relative measure rather than an absolute measure.

It is possible to check the DA of your site using Moz’s Link Explorer, MozBar, which is Moz’s free SEO Chrome extension, or in Keyword Explorer, in the SERP Analysis tab.

As for what can be considered as good or average Domain Authority, the sites with millions of high-quality external links such as wikipedia.com or google.com are at the top of DA range, while small businesses or local websites with little to no inbound links will have much lower DA.

Importance of Domain Authority in SEO

According to the latest figures, 42.6% of link builders use metrics such as DA to determine the efficiency of link building. This goes to show how important DA is in SEO techniques that are implemented in websites. However, DA is not a ranking signal for Google or any other search engine and has no impact on SERP positions. It is used more in relative terms than in absolute terms since it is a ratio of two values.

There are several papers that can shed light on the functioning of DA. For instance, Moz’s web index that is considered to be the best in the industry is used by SEO professionals across the globe. It provides a glimpse of the data that drives Moz’s products, which is useful information that can be acted upon. Also, the DA score is computed by a machine learning algorithm that estimates the frequency of Google’s use of the domain in its search results.

For instance, if the highly authoritative domain such as Facebook has a billion new links, all other sites’ DA would reduce compared to the new score of Facebook. This is because domains with more links and thus greater DA scores occupy more of the high DA positions and thus there is less space at the top for domains with fewer links. Hence, it is much easier to increase the score from 20 to 30 than from 70 to 80.

How to Improve Domain Authority

It is not a one-time process to enhance the domain authority, but a continuous process that requires the implementation of multiple strategies. It involves the process of acquiring quality backlinks, creating good content, and focusing on the technical factors of your website.

Quality Content

The foundation of any website with high DA is quality, uniqueness, and relevance of the content. Ensure you post new content on your website that will be useful to your audience on a frequent basis. For instance, a blog post such as ‘The Impact of Domain Authority on SEO’ will be likely to attract both the first time and repeat visitors.

On-Page SEO

Make sure your content is SEO friendly by following proper heading structures, proper keyword placement, and meta description tags. For example, incorporating the focus keyword “what is domain authority” in the title, headings, and meta description can assist in ranking your page.

Backlinks from authoritative sources are very useful in increasing your DA since it is a quality indicator. Contact leaders in the industry, contribute to other blogs, and use social networks to promote your content.

Internal Linking

Internal linking can also be used in your own pages so that search engines can easily understand the structure of your site and thus enhance the site crawlability and user experience. For instance, the blog post ‘Understanding Page Authority’ can be linked to another blog post ‘What is Domain Authority’ to help the users navigate more of your content.

Mobile-Friendly Website

It is important to have a mobile version of the website since most of the users are browsing the websites using their mobile devices. Make sure you use the responsive design so that your website is equally good to look at and to navigate on any device.

Website Loading Speed

Tips and Strategies to Improve Domain Authority

A site that loads quickly is more enjoyable to the users and is preferred by search engines. One of the ways of determining the speed of your site is by using tools such as Google’s PageSpeed Insights that will inform you of the current status and recommend what can be done to improve on the situation.

Social Signals

Although DA is not directly influenced by social signals such as likes, shares, and comments, they can affect your DA. Share your content on social media platforms in order to enhance its reach.

Bear in mind that the process of increasing your Domain Authority is gradual. It is not about a few days or weeks of work but about the constant and rigorous work and the quality of every aspect of your website. Just keep on practicing, keep on learning and you will notice that your DA score is improving over time.

When discussing “what is domain authority”,, it is necessary to consider quality content, internal linking, and backlink profile. These three elements are the basic ones that can help you increase your domain authority and rank higher in search results.

Quality Content

Content is the king in any SEO strategy and this is why quality content should be produced. It tells search engines such as Google that your website is worthy to be recommended. Moreover, 68% of web users’ interactions start with a search engine, while SEO generates 1000%+ more traffic than organic social media. Hence, the generation of high quality optimized content increases the likelihood of the website appearing on the first page of Google.

Quality content is used to communicate, teach, entertain, or persuade an audience with a certain purpose. It can be in the form of web page, video, social media update, blog post, white paper, infographic, image, and email.

For example, if you are an art supplies company that sells paint brushes and acrylic paint, your content can be relevant to the search query “best painting supplies.” By providing good quality, relevant content, you increase your likelihood of getting on the first page of Google.

Strong Internal Linking

Internal links are the links that are placed within your site that direct the visitors to other pages within the same site. They assist the visitors to find their way around your site and can also assist in the improvement of SEO. Internal links are “super critical” for SEO, as stated by John Mueller, Senior Search Analyst at Google.

Importance of quality content, strong internal linking, and a clean backlink profile

Internal links achieve this through the redirection of the PageRank throughout your site. The number of internal links pointing to a page determines the page’s PageRank. However, it is not the number of links but the quality of the link that is very important in the process.

For instance, if you have an online shop, then you may wish to direct your clients to your most popular or new products through a homepage link. It is useful for the visitor who wants to go directly to the products and buy them and also improves the usability by creating a good internal link structure.

Effective backlinking not only helps in building the credibility of the website among the search engines but also helps in getting better visibility and ranking on the search engine result pages. Backlinks are links on other websites which direct the users to your website. They are like votes of credibility in the world of SEO from other sites.

For instance, if a website about British hedgehogs has a page about a hedgehog awareness drive and includes a link to a useful and pertinent resource that helps in recording hedgehog sightings, then the hedgehog map can be said to have obtained a backlink from the British hedgehog site.

The quality of the content, internal linking, and backlink profile are crucial when it comes to increasing the domain authority of a website. By targeting these areas, you will be able to improve your SEO efforts and thus improve your website’s ranking in the search engine results page.


It is essential to know what is domain authority for anyone that is involved in the SEO business. It is one of the important parameters that gives an idea about the likelihood of a site’s performance in the search engine results.
