Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how likely a website is to rank in search engine result pages (SERPs). DA scores range from 1 to 100, with higher scores indicating greater ranking potential.
Domain Authority is calculated by evaluating multiple factors, including the number and quality of inbound links (backlinks), the age of the domain, and the overall link profile. It is important to note that DA is a comparative metric — it is best used to compare your site against competitors rather than as an absolute measure. Google does not use Moz DA as a ranking factor, but the underlying signals (backlinks, content quality, trust) that contribute to DA are indeed Google ranking factors. Similar metrics include Ahrefs Domain Rating (DR) and SEMrush Authority Score. To improve your DA, focus on earning high-quality backlinks, removing toxic links, and creating authoritative content in your niche.
