Topical Authority
The extent to which a site is recognised as a reliable source on one specific subject.
Analogy Mental model
A cardiologist against a general practitioner. For a heart problem you want the person who does nothing else.
In practice What you actually do
Build it by covering a subject completely rather than broadly. In coffee brewing that means pour over, French press, espresso, cold brew, grind size, water temperature, and the questions between them. Completeness in one field produces the signal.
Where people get burned Pitfalls
It takes time and cannot be faked through volume. A new site covering every branch of digital marketing at once establishes nothing; pick the narrow field where you can be the best answer and expand from there.
