links

JohnMu’s intervention on Site Structure confirms that Google’s primary mechanism for prioritising content is internal link depth (click distance) rather than the superficial folder nesting of a URL string. By explicitly recommending a pyramid architecture over a "flat" model, Mueller resolves the tension between discoverability and context: while flat structures (where everything is one click from the home page) maximise crawl reach, they fail to provide the semantic scaffolding necessary for Google to understand topical relationships and relative page importance. The structural resolution lies in a hierarchy that is "shallow" enough to keep critical content within 3–4 clicks of the root to avoid priority decay, yet "layered" enough to use category and sub-category hubs to triangulate relevance. Ranking durability is a product of architectural signalling, where a page’s authority is validated not just by its own content, but by its logical placement within a broader, internally-linked thematic silo.
