What is Domain Authority?

According to, the company that developed the metric, the higher the authority of a domain, the greater the chances of positioning your content and publications on the first page of search engines

As we will see below, there are several factors that influence the domain authority of a website. 

How does Domain Authority Affect Your Website?

Despite the fact that Google denies that its algorithm makes use of domain authority as one of the factors to define the positioning of pages in search results, SEO experts do not abandon the metric. 

Although Google denies it, in practical experience it is possible to observe that the sites with the highest “Domain Authority” are the ones that naturally appear more times and organically in the first results of the SERPs.

In addition, various surveys and studies have already concluded that more than 70% of the pages that users access after performing a search on search engines (such as Google, for example) are on the first page. 

So make no mistake: domain authority can greatly affect your website, both positively and negatively. 

What Influences Domain Authority?

Now that you know what domain authority is, you should be wondering about the factors that influence this metric.

You already know that with a high Domain Authority, your site is more likely to appear in search results, and, as a result, you will get more visits. 

But after all, what influences domain authority?

According to SEO experts, creating a relevant domain authority is based on several factors, including: 

  • Website Reputation
  • Domain age
  • Number of referring sites (sites that point to your site)
  • Relevance of reference sites
  • Temporary pattern
  • Distributive analysis

In practice, the metric under analysis uses a mathematical combination of the above parameters to determine the size of a domain’s authority and its relevance to search engines. 

How to Improve Domain Authority?

Improving domain authority is not an easy task. 

Therefore, you will need good strategies and a bit of patience to pick up the results, since they cannot be perceived immediately. 

Among the strategies that you can use to improve the authority score of your domain, we can highlight: 

  • Post content frequently – To build authority, try to post content frequently to your site, but not just any type of content. The materials must be complete, they must follow the best SEO practices for the content, and have some type of relevance to your target audience.
  • Invest in referral links: Look for partnerships with other sites that point to external links that may refer to your content. Third-party sites pointing to yours are synonymous with credibility and the fastest way to increase your authority. 
  • Work on your site’s SEO – There are hundreds of SEO metrics and it’s not just about Domain Authority. Therefore, study and try to invest in the best strategies to increase the chances of placing your website on the first page of Google.
