Topical Map
Theoretical FoundationsA Topical Map is a content organization structure divided into CORE sections (main topics) and OUTER sections (supporting topics).
It results from a clustering pipeline: keyword expansion tool, phrase clustering, cluster naming, cluster validation, topical mapping. The map is a pattern, not a commandment; you don't create empty categories 'because they're in the map'. Empty category = negative human signal. Filter to what you actually offer.
Topical Map translates directly into site architecture: CORE clusters become Pillar Pages, and OUTER become supporting pages (SEED/NODE).
In practice, after building a topical map, compare it with your current site structure. Missing CORE clusters are P1 priorities for immediate publication. OUTER clusters you don't have content for should be added gradually. Remember that the map is a plan, not an obligation — better to have 20 excellent CORE pages than 100 empty categories.
