Topical Authority

Topical authority is the reputation a website earns with search engines for covering a particular subject thoroughly and well. When a site answers a subject deeply across many linked pages, search engines start to treat it as a trusted source and show its pages more readily.

It is like becoming the shop everyone names for one thing, the go-to bakery, so people and search engines send others your way. Topical authority matters because a small business usually cannot outrank giants on everything, but by owning a focused subject deeply it can win the searches that matter most to it.
