How does Sitecore manage broken links within a site?

Sitecore manages broken links within a site effectively through a Link Database, which plays a crucial role in monitoring and managing the relationships between items in the content tree. This Link Database keeps track of all links, ensuring that if content is moved or deleted, any corresponding links are updated, or at least flagged for review.

When content that is referenced by links is modified or deleted, the Link Database can detect these changes, allowing developers and content editors to identify broken links quickly. This proactive management helps maintain the integrity of the site's navigation and user experience by ensuring that broken links are addressed promptly.

In contrast to the other possibilities, Sitecore does not ignore broken links or blindly redirect them to the homepage without consideration; neither does it automatically delete unreachable content. Additionally, relying solely on manual removal of links would be inefficient and could lead to a poor user experience. The Link Database's systematic approach provides a more comprehensive and automated solution to managing potential broken links within the site.
