What Causes Links to Break on a Website?

Common Causes of Broken Links

Broken links can develop from various sources, even on well-maintained websites. Understanding these causes helps you prevent them proactively.

Content Management System Changes

When you update your CMS or migrate to a new platform, URL structures often change. Old links that worked perfectly may suddenly become invalid. This is especially common during website redesigns or platform migrations.

Page Deletions and Restructuring

Removing outdated content or reorganizing your site structure can leave orphaned links throughout your site. Internal links pointing to deleted pages are a common source of 404 errors.

External Website Changes

Websites you link to may change their URL structure, move content, or shut down entirely. External broken links are harder to control but equally damaging to user experience.

Human Error

Typos in URLs, incorrect domain names, or copy-paste errors can create broken links. These are often simple to fix but can be difficult to spot without systematic checking.

Protocol Changes

Switching from HTTP to HTTPS or vice versa can break existing links if not handled properly with redirects.

Prevention Strategies

Implement a regular link monitoring schedule, use redirects for moved content, and maintain a clean URL structure. Automated tools can help catch issues before they impact your users and SEO performance.
