# Domain authority

> The accumulated trust a whole site carries — Google's own version is invisible; the public metrics are third-party approximations.

Domain Authority (capital letters) is actually Moz's proprietary score; Ahrefs calls its version Domain Rating. Neither is a Google metric — they are educated guesses at the thing Google does measure: the aggregate strength of a domain's link profile and track record. The useful intuition they capture is real, though: a strong domain lifts every page on it, which is why a new page on an established site can outrank better content on a new domain.

The practical use is directional, not precise: track the trend rather than the number, and treat it as a proxy for 'how much does the web already trust us'. Building it is building links and history — there is no shortcut, which is why an old, well-cited domain is itself an asset worth not throwing away in a rebrand.
