Domain authority (DA) is a metric that predicts how well an entire website or domain will rank on search engine result pages (SERPs). It is scored on a scale from 1 to 100, with higher scores indicating a greater ability to rank. DA is influenced by factors like the quality and quantity of backlinks to the domain, the site's overall content, and technical SEO elements.
A higher domain authority suggests that the website as a whole is seen as more authoritative and trustworthy by search engines, which can help it rank better across a variety of keywords. Like page authority, domain authority is a comparative metric, meaning it helps assess how well one domain may perform relative to others.
