What is Domain Authority?
Domain Authority is a third-party metric (originally developed by Moz) that predicts how likely a domain is to rank in search engine results on a scale from 1 to 100. It is calculated based on the quantity and quality of backlinks pointing to the domain. Google does not use Domain Authority as a ranking factor, but it serves as a useful comparative benchmark.
Why it matters
Domain Authority helps B2B marketers evaluate link-building progress and assess the competitive strength of rival domains when planning content and outreach strategies.
