What is Domain Authority and why is it important?

Domain Authority is a score that indicates the effectiveness of a website in terms of its ability to attract, engage and convert visitors into customers. The score ranges from 1-100 and is calculated using metrics such as backlinks and engagement on social media. Domain Authority was introduced by Moz (formerly SEOmoz) founder Rand Fishkin in 2006, who created the tool as an alternative to PageRank.

Domain authority is an important metric for those who want to make money online, as well as for SEO. Boosting domain authority will increase the organic traffic you get from search engines, making your blog more visible. It can also help you rise in the Google rankings, thus helping you increase your sales.

How is domain authority calculated?

Domain Authority is calculated using more than 200 variables from different sources such as Ahrefs and Majestic SEO. It helps you understand the overall strength of your site along with the external links pointing to your site, which is very important in the SEO process. Domain Authority uses a combination of metrics to determine how authoritative and trusted your website is with search engines. Those metrics are broken down into three categories: link metrics, social metrics, and usage metrics.

Page Authority

Page Authority is a metric that measures the power of a web page to rank in Google search results. It’s calculated from a combination of all the links to a page and the trustworthiness of those links. The higher your Page Authority score, which can be seen in Webmaster Tools, the better off you are at ranking high on Google!


PageRank is a measure of how important Google thinks a web page is. It’s based on the number and quality of links coming into the website, with more valuable sites receiving higher scores. The score ranges from 1-10 with 10 being the most important. The higher the PageRank, the more important Google thinks the page is.

Alternative metrics to domain authority

Trust Flow and Citation Flow are two alternative metrics to domain authority brought to you by Majestic SEO.

Trust Flow and Citation Flow

Trust Flow is a metric that measures the quality of links to a page. It takes into account both the number of incoming links as well as the number of outgoing links, so it’s not just about how many people have linked to your site, but also if they’re good enough to be recommended by other websites. The higher this value is, the better:

  • High trust flow = high-quality backlinks (good for SEO)
  • Low trust flow = low-quality backlinks (bad for SEO)

Citation Flow is a metric that indicates how many pages on the web link to your website. The higher this value, the better:

  • High citation flow = high-quality backlinks (good for SEO)
  • Low citation flow = low-quality backlinks (bad for SEO)

Final Thoughts

It’s important to understand that domain authority is just one factor in Google’s algorithm, and it doesn’t always reflect the quality of a website or the content on it. Google is constantly refining its ranking factors and how they affect search results, so it can be difficult for anyone other than Google itself to know exactly what goes into each decision.

That being said, domain authority does provide some insight into what makes certain sites rank higher than others–and this information can help webmasters improve their sites’ rankings by improving specific aspects of their websites’ structure or content.
