Domain Authority
A zero-to-one-hundred score from Moz that predicts how likely a domain is to rank, computed from the shape of its backlink profile.
Analogy Mental model
A university's overall ranking. Graduates of a highly ranked institution find doors open more easily, whatever their individual merits happen to be.
In practice What you actually do
Use it comparatively, never absolutely. A forty in your niche has more ranking headroom than a twenty held by a direct competitor, and that gap tells you where to aim outreach. The MozBar extension gives a quick read while you browse a prospect's site.
Where people get burned Pitfalls
Domain Authority is Moz's proprietary metric; Google does not use it, and an internal gain is not a business result. Report earned links and traffic growth instead of a score only one vendor computes.
