Domain Authority Score
Learn what domain authority score means in SEO, how this numerical metric predicts website ranking potential, and its role in link building evaluation
Domain authority score is a metric developed by SEO tool providers to predict a website’s ability to rank in search results. Scored on a scale from 1 to 100, it considers factors like the number and quality of backlinks pointing to the domain. For link building, domain authority score is widely used to evaluate potential link partners and prioritize outreach targets. Higher domain authority generally correlates with more valuable backlinks. However, it should not be the sole criterion for link evaluation — relevance, traffic, and content quality are equally important. Domain authority is a comparative metric, most useful when benchmarking against competitors rather than as an absolute measure.
