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.
