Question

Can visitors and crawlers find the intended pages through useful links?

Nodes

Page; Link; Anchor; Navigation context

Relationship sketch

page → linked page
link → anchor and location

Evidence inputs

Authorized crawl, initial/rendered HTML as relevant, intended navigation, canonical route list.

Implementation

Inspect reachable components and important pages with no incoming links. Evaluate navigational usefulness alongside graph metrics. Keep page purpose and user journeys ahead of arbitrary link quotas.

Acceptance checks

Important public pages are reachable from intended entry points
Actual href targets work
Any reported orphan definition and crawl scope are explicit

Do not infer

A crawl of only part of a site cannot prove whole-site orphan status.

Publication boundary

Navigation is public; diagnostic reports normally private.
