A page with no outgoing links
Everything on this page is healthy except the complete lack of links.
Why dead ends are a problem
Search crawlers move through a site by following links. When a page has no outgoing links, any link strength that reaches it stops there, and a crawler has no next page to discover from this point. People hit the same problem when they finish reading and have nowhere useful to go except the browser back button.
What a healthy page should do
Most pages should point somewhere sensible after the main content: a related article, a parent category, the homepage, or the next step in a flow. The exact destination depends on the page, but the pattern is the same. A useful page should help visitors continue, and it should help crawlers understand how this URL fits into the wider site instead of treating the page as an isolated endpoint.
