Topical authority

What topical authority means

Topical authority is an industry term for how thoroughly and credibly a website covers a subject. It isn't a Google metric or score. The idea is that a site with deep, connected, accurate content on a topic is more likely to be seen as a reliable source on it than a site with one thin page.

Seen in practice

A specialist in sash window restoration writes detailed pages on draught-proofing, replacing cords, glazing options for listed buildings and when repair is better than replacement. Over time the site ranks for many sash window questions, and enquiries come from across the region.

Why it matters for your content

Small specialist businesses can build real depth on the narrow topics they know best. A plumber who explains every common boiler fault on models he services, or a solicitor who covers every stage of probate clearly, can compete with much larger generalist sites on those topics.

For a small business, the practical version is simple: cover the topics you sell properly before branching out. A site that answers every common question about one service is more convincing than one that skims ten.

Checking your own pages

List the questions customers ask about your main service and see how many your site answers well. Check whether those pages are linked together and whether they show real experience, such as photos, examples and named authors. Gaps in that list are where to write next.

Traps to avoid

• Writing about everything vaguely instead of one area in depth.
• Publishing lots of thin posts and calling it authority.
• Covering topics you don't actually work in.
• Treating it as a score you can measure precisely.
