What is Domain Authority?

Domain Authority is a metric to predict a websites ranking on search engine results pages. It rates a website on a scale of 1 to 100, where 1 is the worst and 100 is the best.

How does Domain Authority Work?

Moz, an SEO consulting and research company introduced this measurement system to estimate the rankings of the websites of search engine results pages. It takes multiple factors into consideration while calculating the domain authority including linking root domains and the number of total links. They claim this score is useful for comparing websites and tracking the ranking strength of a website over the years.According to this measurement system, the sites with a large number of high-quality external links are at the top of the scale and the small companies and websites with less inbound links perform poorly. Websites start with a score of one on the scale in the beginning.It is important for a website to maintain a score higher than its competitors in order to remain on the top of the search engine results page. As it is a comparative tool there is no absolute good or bad score in domain authority.However, Google, the largest search engine in the world insists they do not use any metrics to rank pages. They have made it clear over and over again that they do not depend on domain authority or any such measurement tools while ranking the pages on their results page. They claim to assess a website in its totality.As the process of PageRank is highly secretive, the domain authority metric is widely used by businesses to evaluate their domain strength.
