Domain Authority

Domain Authority (DA) is a search engine ranking score developed by Moz that predicts how well a website will rank in search engine results pages (SERPs). Scored on a scale of 1 to 100, with higher scores indicating greater ability to rank, Domain Authority is calculated using multiple factors including linking root domains, number of total links, MozRank, and MozTrust scores. While not a direct Google ranking factor, DA serves as a useful comparative metric for SEO professionals to evaluate website strength, track SEO progress over time, and assess competitive landscapes in search rankings.
