Why Broken Links Hurt Your Rankings
What Are Broken Links?
Broken links are hyperlinks that point to nonexistent or inaccessible pages. These errors typically return 404 (Not Found) or 410 (Gone) responses.
They happen for many reasons:
- Deleted pages
- Incorrect URLs
- Moved content without redirects
- Expired external resources
SEO Impact of Broken Links
Google wants to deliver the best possible experience to searchers. When your site has broken links, it signals poor maintenance and reduces trust.
User Experience Issues
Broken links interrupt navigation and frustrate readers. Poor UX affects metrics like bounce rate and time-on-page—key behavioral signals Google monitors.
Indexing & Crawlability Problems
Search engines use bots to crawl your content. Broken internal links can block important pages from being discovered or indexed. For deeper insight, explore indexing workflows (https://mondaytools.com/tag/indexing) and technical SEO strategies (https://mondaytools.com/tag/technical-seo).
Loss of Link Equity
When a page with backlinks disappears or breaks, you lose valuable ranking authority that those links once contributed.
Why You Should Use Online SEO Tools for Broken Link Checks
Manual Checking vs Automated Tools
Manually verifying every link on a website is nearly impossible—especially if you publish regularly or have hundreds of pages.
Benefits of Using Online SEO Tools

- Fast full-site scans
