Domain Authority
A reputation signal estimating how well a domain ranks, driven largely by quality inbound links.
- glossary
Domain authority (DA) is a third-party metric — popularized by tools like Moz, Ahrefs, and Semrush — that estimates how likely a domain is to rank well on a SERP, with Google's own underlying signal being the PageRank-derived link graph. The primary driver is backlinks: inbound hyperlinks from other websites pointing to your domain. Not all links carry equal weight; a single link from a high-traffic news outlet can outweigh hundreds of links from obscure directories. The quality and relevance of anchor text used in those links also shapes how search engines interpret what the domain is authoritative about. Because domain authority accretes over years through consistent publishing, earning links, and avoiding penalties, an aged domain with strong DA can command a significant aftermarket premium — buyers are effectively acquiring an SEO head-start that would take years and significant budget to replicate from scratch.
