Every website accumulates broken links over time. Pages get deleted, URLs change, external sites disappear, and typos slip into content. A broken link leads users to a 404 error page instead of the content they expected. Many site owners search for guidance from trusted sources like Moz to understand whether broken links really matter for SEO. The consensus among experts is clear: a few broken links will not destroy your rankings, but unchecked broken links harm user experience, waste link equity, and make your site look neglected. In this article we explain how broken links affect SEO, what Moz recommends, and how to find and fix them efficiently.

What Are Broken Links?
A broken link, sometimes called a dead link, is a hyperlink that points to a page that no longer exists or cannot be reached. Most broken links return a 404 Not Found status code, though some return other errors such as 410 Gone, 500 server errors, or DNS failures. Broken links can be internal, pointing to pages on your own site, or external, pointing to other websites. There are also broken backlinks, which are links from other sites pointing to pages on your site that no longer exist.
What Moz Says About Broken Links
Moz has long emphasized that broken links create a poor user experience and can waste valuable link equity. Moz Pro's Site Crawl flags 4xx errors as critical issues because they block users and crawlers from reaching content. Moz's Link Explorer also highlights top pages with broken backlinks, recognizing that these represent lost authority that can often be reclaimed. Google itself has stated that 404 errors are a normal part of the web and do not directly harm a site's rankings. The real cost comes from the indirect effects.
How Broken Links Hurt SEO
Poor User Experience
Users who click a link and land on an error page may become frustrated and leave. High abandonment and low engagement send negative signals about site quality and reduce conversions.
Wasted Link Equity
Backlinks pointing to deleted pages pass little or no value. If an authoritative site links to a URL that now returns a 404, that authority is effectively lost. Internal links to broken pages also waste the flow of authority within your site.
Crawl Inefficiency
Search engine crawlers that encounter many broken links spend time on dead ends rather than discovering valuable content. For large sites, this can affect how quickly new pages are found and indexed.
Quality Perception
Numerous broken outbound links suggest that content is outdated or poorly maintained. This can undermine trust with users and may reduce the perceived quality of your pages.
How to Find Broken Links
- Moz Pro Site Crawl: Identifies 4xx errors and shows which pages contain links to them.
- Moz Link Explorer: Reveals top pages with broken backlinks from external sites.
- Google Search Console: The Pages report shows URLs returning 404 errors that Google has discovered.
- Screaming Frog SEO Spider: Crawls your site and lists every broken internal and external link.
- Ahrefs and Semrush: Provide broken backlink reports and site audit tools.
How to Fix Broken Links
- Update internal links: Edit content to point to the correct, live URL.
- Implement 301 redirects: Redirect deleted pages to the most relevant existing page, especially if they have backlinks or traffic.
- Restore valuable content: If a deleted page had strong links and traffic, consider republishing it.
- Replace or remove external links: Update outbound links to new sources or remove them if no replacement exists.
- Reach out for backlink updates: Ask linking sites to update links to your current URLs.
- Use 410 for intentional removals: If content is permanently gone with no replacement, a 410 status clearly signals removal.
Create a Helpful 404 Page
Even with diligent maintenance, users will occasionally hit a 404 page. Make it helpful by including a clear message, a search bar, links to popular pages, and navigation to key sections. A well-designed 404 page keeps users on your site rather than sending them back to search results. Ensure it returns a true 404 status code rather than a 200, which would create soft 404 issues.
Broken Link Building Opportunities
Broken links on other websites can be an opportunity. Broken link building involves finding dead links on relevant sites, creating or identifying content on your site that serves as a good replacement, and suggesting it to the site owner. This tactic provides value to the other site while earning you a relevant backlink.
Prevention Tips
- Schedule monthly or quarterly crawls to catch broken links early.
- Plan redirects whenever you delete or move content.
- Avoid changing URLs unnecessarily.
- Link to reputable, stable external sources.
Conclusion
Broken links are not a direct ranking penalty, but they harm user experience, waste link equity, and reduce crawl efficiency. Moz and other experts recommend finding and fixing them regularly as part of good technical SEO hygiene. Use tools like Moz Pro and Google Search Console to identify issues, apply redirects and link updates strategically, and turn broken backlinks into reclaimed authority. A well-maintained site is easier for users to navigate and easier for search engines to trust.
