Orphan pages — indexable URLs with zero inbound internal links — receive no PageRank flow and often fall out of the index entirely, wasting whatever you spent producing them. Pages buried more than 3 clicks from home get crawled infrequently and inherit minimal authority, which caps their ranking ceiling regardless of content quality. Both failure modes commonly hide high-intent commercial pages that should be front-and-center.
Low because reachability issues suppress individual pages but do not affect well-linked core routes.
Generate a reachability report by crawling from home with a tool like Screaming Frog, then add contextual links from relevant hubs to every orphan. Update navigation in components/nav.tsx to surface buried categories at depth 1 or 2, and add breadcrumbs via app/layout.tsx so every page declares its ancestor chain.
