Topical Authority & Entities: Comprehensive Topic Dominance
Topical authority is the search system’s judgment that your site comprehensively and coherently covers a subject. HEG creates that judgment by assigning one URL per entity, nesting L2 support under clear L1 pillars, and circulating PageRank inside hermetic silos instead of random cross-links.
- One primary entity per URL; merge near-duplicates aggressively.
- Silo vertically (L0→L1→L2→L3) with limited sibling links inside the cluster.
- Programmatic pages must still add information gain — templates alone are not authority.
- Never link across unrelated L1 silos from L2 without climbing the hierarchy.
1. Knowledge graphs as the basis of search understanding
Modern retrieval matches documents to entities and relationships (subject–predicate–object), not only strings. Ambiguous naming, competing canonicals, and orphan pages weaken topical authority even when word count looks high.
Coverage without structure is noise. Structure without unique evidence is a hollow graph. HEG requires both: clean topology and L3 proof.
2. The two pillars of entity scaling
Siloing & internal linking keeps authority circulating inside a topic. Programmatic SEO scales supporting entities only when each URL still earns its place with distinct attributes, data, or intent match.
