What is Domain Authority? 5 Free Tools to Check

Domain Authority (DA) is a vital metric that helps digital marketers, website owners, and SEO professionals understand the strength of a website in search engine rankings. Originally developed by Moz, Domain Authority is a score ranging from 1 to 100 that predicts how well a site will rank on search engine result pages (SERPs).

A higher DA indicates a stronger website with better chances of ranking higher, while a lower score suggests that the site may need more SEO work, quality backlinks, and content optimization. Although DA is not a direct ranking factor used by Google, it is widely considered an essential benchmarking metric in SEO strategies.
