What Is a Broken Link?
A broken link, also known as a dead link or broken backlink, is a hyperlink that no longer leads to its intended destination. Instead of opening a valid page, it usually results in an error like “404 Not Found.” This typically happens when a webpage is moved, renamed, or deleted without setting up a proper redirect. Over time, these links can accumulate across a site, especially on older pages or blogs.
Why Do Broken Links Matter?
Broken links are more than just a nuisance—they negatively impact both user experience and your website’s SEO performance. Visitors clicking on broken links are likely to leave your site in frustration, which can increase bounce rates. From an SEO standpoint, search engines like Google may view sites with excessive broken links as poorly maintained, which can affect your rankings and overall domain authority.
How to Fix Broken Links
Once a broken link is discovered, you have a few options depending on the situation. If the destination page still exists under a different URL, simply update the link. If the page has been permanently removed and there's no suitable replacement, you might choose to remove the link entirely. In some cases, setting up a 301 redirect from the old URL to a new relevant page ensures users and search engines are sent to the right destination. Alternatively, you can replace the link with a similar page from another trusted source.
How Broken Links Affect SEO
Search engines evaluate websites based on quality, structure, and usability. Broken links disrupt these signals by interrupting the flow of link equity (also called "link juice"), making it harder for search engines to crawl and understand your site. Too many dead links can be a red flag, suggesting the site is outdated or poorly maintained, which can result in lower rankings.
In addition, broken links waste crawl budget, slow down indexing of important pages, and can erode user trust—especially if key content appears unavailable.

Frequently Asked Questions
How often should I check for broken links?
For active websites, weekly automated scans are recommended, with monthly comprehensive audits. High-traffic sites or e-commerce platforms should implement daily monitoring for critical pages and user paths.
Do broken links really hurt SEO rankings?
Yes, search engines view broken links as indicators of poor site maintenance and quality. While a few broken links won't destroy rankings, accumulating many can signal neglect and negatively impact search visibility.
What's the difference between 404 and 500 errors?
404 errors mean the page doesn't exist, while 500 errors indicate server problems. Both need attention, but 500 errors are more urgent as they suggest technical issues that could affect your entire site.
Should I remove or redirect broken external links?
For temporarily broken external links, monitor them for a few weeks. If permanently broken, either find alternative sources, remove the links, or replace with archived versions from archive.org when appropriate.
Can broken links affect conversion rates?
Absolutely. Broken links in checkout processes, product pages, or call-to-action paths directly prevent conversions. Studies show that 40% of users abandon sites after encountering broken links in critical user journeys.
How do I prioritize which broken links to fix first?
Prioritize based on traffic volume, conversion impact, and SEO value. Fix broken links on high-traffic pages, conversion paths, and pages with significant inbound links first for maximum business impact.
What tools can automate broken link checking?
Many SEO tools offer automated link monitoring including Google Search Console, Screaming Frog, Ahrefs, and specialized link checkers. Choose tools that offer scheduling, alerts, and detailed reporting for efficient management.
How long should I wait before removing a broken external link?
Monitor broken external links for 2-4 weeks to see if they're temporarily down. For permanent failures, decide based on content value - remove if non-essential, or find alternative sources if the reference is important.
