What is Topical Map?
A Topical Map is a site's topic coverage blueprint — a Pillar Page at the center radiating N subtopics. A complete Topical Map signals to Google and AI engines that you are 'the authority on this domain', not 'someone who wrote a few posts'.
How do you apply it in practice?
Build: start from the core entity, enumerate 5 layers (definition/types/comparison/cases/tools), ≥5 pages per layer, bidirectional internal links.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Topical Map" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

Topical Authority
Topical Authority is Google's overall judgment of how comprehensively you cover a topic. The more complete the coverage, the tighter the internal links, and the higher the originality, the stronger the authority. It has overtaken single-page PageRank as a core ranking factor since 2024.
Pillar Page
A Pillar Page is a long survey covering a broad topic (3,000–8,000 words), linking to N subtopic pages and back-linked by them. The standard structure for building Topical Authority and GEO entity salience.
Topic Cluster
A Topic Cluster is a Pillar Page plus N subtopic pages connected by two-way internal links. It signals to Google that you cover a topic comprehensively and is the standard tactic for building Topical Authority.
