Domain Authority (DA) is a website metric developed by Moz. It is one of the most significant numbers known to SEOs. They rate a website on a scale of 1-100, (100 being the best and 1 being the worst). The greater your DA, the more likely you are to have strong traffic and high rank. Moz’s Domain Authority is a way to gauge how your website would perform competitively when pitted against other websites in your niche.

Amongst all the SEO factors, the key elements which make up the DA are – The website’s Age, Popularity, Backlinks, the number of links pointing to the site and the number of linking root domains – mainly the number of other sites linking to your site! (See MozTrust, MozRank, etc.)
