Domain authority is a search engine ranking score that estimates a website’s ability to rank on Search Engine Results Pages (SERPs). Domain authority ranges from a score of 1 to 100. The higher your score, the better your website will rank.
Domain Authority is scored on a 100-point logarithmic scale. Note that it's easier to increase your score from 20 to 30 than it is to grow from 70 to 80.
Domain authority is a comparative tool, therefore, having a higher score than your competitors must be the goal to be good.
Domain Authority metrics are included in lots of SEO and online marketing platforms in the web. Moz ecosystem is the suggested one by Popupsmart.
Domain Authority is not influenced directly by a component. The best way to affect the Domain Authority metric is to improve your overall SEO and to obtain more links from other high ranking web pages.
