Topical authority
The trust a site earns by becoming genuinely useful across one subject, not by publishing endless keyword variations.

What it is
Topical authority is the shorthand for a site becoming a trusted resource on one subject through deep, accurate, connected coverage and a reputation beyond its own pages. It is not one Google score you can look up. It is the compound effect of answering the important needs in a field, showing real expertise, earning relevant links, and making the relationships between pages obvious.
Reach for it when isolated keyword pages have stopped compounding. Map the subject into a topic cluster: one strong overview, focused pages for distinct reader needs, and contextual internal links between them. HubSpot popularized that hub-and-spoke pattern in the 2010s, but the structure only works when each spoke contributes something worth citing.
The gotcha is confusing coverage with page count. Publishing 100 thin variations of the same answer creates cannibalization, not authority. Merge overlaps, update decayed pages, cite primary evidence, name real authors where authorship matters, and earn recognition from relevant sites. A content graph can clarify expertise you possess; it cannot manufacture expertise you do not.

Build a topical-authority plan for [subject] using the supplied site crawl, backlink export, and Google Search Console Performance report. Group existing pages and queries into distinct reader needs, select one pillar page per major need, and map supporting pages with descriptive <a href> internal links to the pillar and relevant siblings. For each gap, specify the audience question, evidence required, intended author, and why a new page is better than expanding an existing one. Flag pages that compete for the same intent, merge or redirect overlaps with HTTP 301, prioritize decayed pages for updates, and propose three original assets capable of earning relevant backlinks. Do not invent search volume, expertise, or sources.
