Broken links are hyperlinks that lead to non-existent pages, often resulting in error codes like 404. They occur due to deleted content, URL changes, typos, server errors, or redirect issues. Broken links harm SEO, frustrate users, and reduce brand credibility. This guide explains what broken links are, why they happen, their impact, and how to detect, fix, and prevent them.

🔎 What Are Broken Links?

Broken or dead links are hyperlinks that no longer work, leading users to error pages.

Types of broken links include:

• Broken internal links – lead to non-existent pages on your own site.
• Broken external links – lead to missing content on other sites.

Broken backlinks – exist on other sites but point to missing pages on yours.

⚠️ What Causes Broken Links?

There are several common causes:

1. Deleted or moved content – Pages removed during redesigns or updates.
2. Changes in URL structure – Renaming folders or categories without updating links.
3. Misspelled URLs – Typos when inserting links.
4. External content removal – Linked resources deleted or updated by other sites.
5. Server or protocol issues – Downtime, HTTPS/HTTP mismatches, or blocked resources.
6. Redirect chains or loops – Circular redirects make pages inaccessible rather than technically missing; fixing them requires editing redirect rules, not restoring content.
7. AI-generated or automated content restructuring – Tools that automatically move, merge, or reorganize page content can break previously valid URLs if the project is not republished afterward.

Soft 404 errors – Pages returning “not found” messages without proper error codes.

Note on CMS/site-builder 404s: Some CMS or site-builder platforms (including Search Atlas Website Builder) can generate pages that return a 404 even when a button or navigation link points to them. This typically happens when the underlying page is empty or unpublished. Verify that pages are fully published and contain content, not just linked in navigation.

Note on URL regeneration: Some CMS platforms may regenerate previously deleted URLs, which can cause confusion about which URL is canonical and may unintentionally reinstate broken states. Audit URL changes carefully after content deletion to avoid link resurrection.

Note on audit tool lag: Site audit tools (including Site Lens) may show a delay between when a 404 is resolved and when the tool updates its status.

If the issue persists, contact support, as this may indicate a reporting discrepancy rather than an actual broken link.
