Domain authority

Domain authority (DA) is a ranking score. This score was developed by the American company Moz. The score indicates how the Web site will rank in Google’s search results (SERP). The score is between 0 and 100. We do not recommend trying to reach 100 or trying your best to do so. Only websites like Facebook and Google achieve scores of 100. Also, it is a logarithmic scale, which means it is easier to go from 0 to 10 than from 10 to 20. (1)

Pro tip: Here you can view the DA of websites for free (a few a day).

How is domain authority calculated?

Domain authority is calculated based on a number of factors. Basically, you get a higher score if you optimize your entire site. These factors can help:

  • the number of inbound links;
  • The number of referring domains;
  • Provide a strong internal link structure;
  • on-site optimization;
  • The domain authority of the websites that link to you;
  • Make sure your website is SEO-ready;
  • informative and meaningful content.

How to use the DA.

Domain authority is not a ranking factor used by Google. It’s better to use it as a comparison score for other websites (e.g., your competitors).

This allows you to peer at your competitors and see what you can optimize about your site to in all likelihood rank higher in search results than your competitor.

5. Review your DA scoreYour DA score is displayed in the results. It is a number between 1 and 100, with a higher number indicating higher authority. Note that this is just one of many factors that affect search engine ranking.
6. Analyze the resultsIn addition to your DA score, the Link Explorer tool provides other useful information, such as the number of inbound links to your site, the quality of those links and more. Take the time to analyze these results and understand what they mean for your SEO strategy.
