Domain Authority or DA is a search engine score created and developed by SEO platform MOZ to determine how well a website will rank on SERPs.
Not to be confused with Page Authority or PA which measures the authority of an individual page.
A domain authority score is measured from 1 to 100. The higher the score the higher the authority a domain is believed to have. The closer your score to 100, the better the ranking and more organic traffic your site will have.
DA combines 40 different metrics, most created and monitored by Moz.
The most common metrics used are:
Link profiling examines both external and internal links, to and from a website. A page which receives links from reputable sites, as well as links to valuable sources, will score well.
Evaluates the overall popularity of a site by calculating the quantity and quality of the websites linking to it.
Assesses the trustworthiness of sites linking to yours. Links from trustworthy sites like large businesses, government pages or universities result in a higher MozTrust rating.
While DA doesn’t directly impact your rankings in Google SERPs, it’s a useful comparative metric which indicates how your site’s external link profile compares to competing sites.
It’s also a fairly reliable indicator of your entire site’s ranking.
It’s a good idea to check your site’s DA regularly.
