Site Architecture
How pages are organised and linked to each other, which determines what gets found, what looks important, and what gets buried.
Site architecture is the shape of a site as a crawler experiences it: which pages exist, how they nest, and what links to what. It sets discovery — a page nobody links to is a page nobody finds — and it distributes authority, because links are how ranking signals move around a domain.
The workable rule is that anything important should be reachable from the homepage in a few clicks, and pages covering the same topic should link to each other rather than each hanging off the navigation in isolation. Depth is not inherently bad; orphaning is.
Architecture is also a URL question. Paths that describe the hierarchy — /glossary/canonical-tag/ rather than /p?id=418 — are readable to a person deciding whether to click and to a machine working out how a page relates to its neighbours.
