The definition
A third-party estimate (Moz's originally) of how likely a site is to rank, based mostly on its link profile. Not a Google metric — a useful proxy, nothing more.
Why it matters to an owner
Directionally useful for comparing yourself to competitors; meaningless as a goal in itself.
This is the work. Want it done?
Everything here is free to use yourself — that’s the point. If you’d rather a senior marketer just handle it, in your accounts and your name: 20-minute call, no pitch deck.
