Domain Authority (DA)

Domain Authority (DA) is a third-party metric developed by Moz to estimate how likely a domain may be to appear in search results relative to other domains in its system. It is not a Google ranking factor, an official Google score, or a guarantee of search traffic. The number depends on Moz's own data and modeling, so it should not be confused with a page's actual position for a particular query. A handyman business comparing competitors may encounter DA in SEO tools, but should also examine relevant content, search results, local visibility, and genuine business outcomes. No single third-party score summarizes overall website quality.
