1.2 Indexability & statusHighInferred

Orphan page

An orphan page has no internal links pointing to it, so crawlers and users can only reach it by luck. If a page matters, it should be linked from somewhere relevant.

What it is

Indexable page with no internal links to it.

Why it matters

Hard for Google to discover and to assess importance; weak internal-signal flow.

How to fix it

Link to it from relevant hubs and navigation.

How to find it on your site

  1. Compare your full URL inventory from sitemap, analytics and logs against the internally linked URLs from a crawl.
  2. URLs in the first set but not the second are orphans.
  3. Decide whether each orphan deserves to exist.
  4. Link the keepers from relevant hubs and remove or redirect the rest.

Cross-reference to ranking and citation factors

Internal links are how authority and crawl priority flow. An orphan receives almost none, so even strong content underperforms.

Impact

Medium-high discoverability/authority. Inferred from crawl/linking guidance.
