How Does Google Assess Domain Authority, and Does It Affect Search Rankings?
First, it’s important to clarify that Domain Authority is not a Google metric....Other platforms have similar proprietary metrics:
Domain Rating (DR) by Ahrefs
Authority Score by Semrush
These scores are based on link profiles, content strength, and other factors—attempting to model Google’s own internal evaluation systems.
What SEOs Get Wrong About Backlink Quality
One of the most prevalent errors in backlink analysis is the overreliance on metrics like Domain Authority (DA), Domain Rating (DR), or Trust Flow....Google does not use Domain Authority or Domain Rank, these are proprietary scores developed by Moz, and DR by Ahrefs....The Reality:
What matters more than a high DA or DR is the contextual relevance of the linking site.
