Broken Links SEO
A broken link is a hyperlink that points to a page or resource that no longer exists, typically returning a 404 or 410 error.
Key facts
- Broken links can be internal (within your site) or external (pointing to other sites).
- They occur when a page is deleted, moved without a redirect, or the target server fails.
- Search engines may waste crawl budget on broken links, reducing indexing of other pages.
- Persistent broken links can harm site credibility and user trust.
- Tools like Google Search Console and crawlers can help identify broken links.

How Broken Links Affect SEO
Broken links hurt user experience. A visitor who clicks a broken link sees an error page instead of the content they expected. That frustration can drive them away.
For search engines, broken links waste crawl budget. Googlebot spends time following dead paths instead of indexing useful pages. Over time, this can slow discovery of new or updated content.
Broken links also affect Crawlability. If a site has many broken links, search engines may see it as poorly maintained. That can reduce trust in the site's overall quality, though Google has not confirmed a direct ranking penalty.
Common Causes of Broken Links
Broken links happen for several reasons. The most common is deleting or moving a page without setting up a 301 redirect seo. When the old URL no longer exists, any link pointing to it breaks.
Other causes include changing the URL structure during a site migration, removing a file or image, or the target server going down. External sites may also delete or move content you linked to.
- Page deleted without a redirect
- URL changed after migration
- External site removed or moved content
- Server error (500, DNS failure)
How to Find Broken Links
To check for broken links on your website, use Google Search Console. The 'Page indexing' report shows URLs that return 404 or 410 errors. You can also use a dead link checker tool like Screaming Frog or Ahrefs to crawl your site and list all broken links.
For external links, tools like Seobility can scan your pages and report outbound broken links. Manual checks are possible but time-consuming on large sites.
Regular audits help catch broken links early. I recommend running a crawl monthly or after any major content update.
How to Fix Broken Links
Once you find a broken link, you have three options. The best fix depends on the situation.
For internal broken links, updating or redirecting is usually straightforward. For external broken links, you may need to find an alternative source or remove the link. If the broken link is a backlink from another site, you can contact the site owner and ask them to update it. Similarly, an inbound link that breaks can lose referral traffic.
When fixing broken links, also consider the Link structure of your site; a clean structure reduces future breaks. For external links, a External Link that breaks may need replacement. If the broken link is from a high-authority source like Wikipedia, check Wikipedia Backlinks for guidance. Finally, ensure the target page does not return a 404 seo error after your fix.
- Update the link to point to a working page or resource.
- Set up a 301 redirect from the old URL to a relevant new page.
- Remove the link entirely if no suitable replacement exists.
Preventing Broken Links in the Future
Prevention saves time. Always plan redirects before deleting or moving pages. Use a consistent URL structure and avoid unnecessary changes.
When linking to external sites, consider using a link checker plugin or service that alerts you when a destination breaks. For example, how instagram seo works is unrelated, but the principle of monitoring external links applies across platforms.
Also check non-HTML resources like PDFs and images. A broken image link can harm user experience just as much as a broken page link. Finally, ensure your ssl seo is correct; HTTPS issues can cause links to break if the certificate is invalid.
Common mistakes
- Treating every 404 as a problem instead of distinguishing between intentional removals and fixable broken links. You waste time on pages you meant to delete, and miss real broken links that need fixing.
- Deleting or renaming URLs without mapping redirects first. All links pointing to those URLs become broken, harming user experience and crawl efficiency.
- Ignoring broken links in navigation, footers, image links, PDFs, and other non-body content. These links still affect users and search engines, and can create a poor site impression.
Questions
What is the best broken link checker?
There is no single best tool; it depends on your needs. For a free option, Google Search Console is reliable for finding 404 errors on your site. Paid tools like Screaming Frog or Ahrefs offer more detailed crawls and external link checks.
What is the best free broken link checker?
The best free broken link checker is Google Search Console for internal links. For a more comprehensive free crawl, you can use the free version of Screaming Frog (limited to 500 URLs) or the W3C Link Checker.
Do broken links hurt SEO?
Broken links do not directly cause a ranking penalty, but they can hurt SEO indirectly. They waste crawl budget, reduce user trust, and may signal poor site maintenance. Fixing them is a best practice for overall site health.
