Domain Authority
A third-party metric estimating a domain's overall ranking strength.
Domain Authority (DA) is a Moz metric scored 0-100 based on linking domains, link quality and site signals. Equivalent metrics from other tools include Ahrefs Domain Rating (DR), Semrush Authority Score and Majestic Trust Flow. None are official Google signals but all serve as useful third-party proxies for competitive analysis.
