When it comes to maintaining a high-performing website, ensuring that all links work as expected is crucial—not just for user experience, but also for SEO. Broken links (also known as 404 errors) are dead ends for both visitors and search engines, and they can significantly impact your website’s rankings and performance in search results.
In this article, we’ll explain what broken links are, why they are harmful to SEO, how to identify and fix them, and the tools and best practices you can use to keep your website in top shape. Whether you're a small business owner, an eCommerce store, or a blogger, understanding how broken links affect your SEO and how to fix them is essential for long-term success.
What Are Broken Links?
A broken link is any hyperlink on a website that no longer leads to its intended destination. This could be due to the target page being removed, renamed, or moved without updating the original link. Broken links are often categorized into two types:
Internal Broken Links: These links point to pages within your own website that are no longer accessible (e.g., pages that were deleted, URLs that changed, or broken redirects).
External Broken Links: These links point to external websites that are no longer available or have been moved (e.g., a blog post linking to an outdated external resource).
When either type of broken link is clicked, it typically results in a 404 error page, indicating that the page could not be found. This not only frustrates users but can also signal to search engines that your website is not well-maintained.
Why Broken Links Are Harmful for SEO
1. Negative Impact on User Experience (UX)
A website with broken links can significantly diminish the user experience (UX). When users click on a link and are sent to a 404 error page, it disrupts their journey through your site. This can lead to:
Increased bounce rates: Visitors will leave your site quickly if they encounter broken links.
Decreased engagement: Users are less likely to engage with your content or explore additional pages if their browsing experience is interrupted.
Lower trust: A website full of broken links may seem unprofessional and poorly maintained, causing users to lose trust in your brand or content.
2. Lower Search Engine Rankings
Google and other search engines are designed to prioritize websites that provide a seamless user experience. If Google’s crawlers encounter broken links while indexing your site, it may interpret this as a sign of poor-quality content or a neglected website, which can result in:
Lower rankings: Broken links can cause your site to lose trust with search engines, potentially leading to lower rankings in the search results.
Inefficient crawling: Googlebot may waste crawl budget on broken links, meaning it might not spend as much time indexing valuable content on your site.
Lost link equity: External links that point to broken pages on your website lose their link equity, meaning the authority passed from those links is not transferred to your pages.
3. Negative Impact on Site Authority
When you have internal broken links, the structure of your website becomes fragmented. Internal linking is an important ranking factor for SEO, as it helps Google understand the relationship between pages. If internal links are broken, Google may not effectively index your most important content, reducing the overall authority of your site.
How to Identify Broken Links
Finding broken links on your website might sound like a daunting task, but there are various tools and strategies that make it easier. Here are some common methods:
1. Use SEO Tools to Scan for Broken Links
Several SEO tools allow you to easily identify both internal and external broken links. Some of the most popular options include:
Google Search Console: This free tool provides insights into your website's health, including 404 errors caused by broken links.
Screaming Frog SEO Spider: A powerful tool that crawls your website and identifies broken links, redirects, and other issues.
Ahrefs: Ahrefs offers a detailed audit tool that scans your site for broken links and other SEO issues.
Semrush: This all-in-one SEO tool also includes features for identifying broken links on your website.
Broken Link Checker: This free online tool scans your website for broken internal and external links.
2. Check Your Website Manually
Although using a tool is far more efficient, you can also manually check for broken links by clicking through your website’s pages and following the links. This method is more time-consuming and less effective for larger websites, but it can still be useful for smaller sites or specific pages you want to check.
3. Monitor Social Media and External Backlinks
Occasionally, external websites that link to your content will remove or change their URLs. To stay on top of broken external links, you can use tools like Ahrefs or Moz to monitor backlinks pointing to your site. If any external links lead to a 404 page, reach out to the referring site and request an update.
How to Fix Broken Links
Once you’ve identified broken links, it’s time to fix them. Here’s how you can address both internal and external broken links.
1. Fix Internal Broken Links
Update the URL: If a page URL has changed, update the link to reflect the new URL. This can be done by either editing the existing link or redirecting the old page to the new one (using a 301 redirect).
Create a New Page: If a page has been deleted and cannot be recovered, consider creating a new page with similar content and linking to it from the same location.
Use a Redirect: For pages that no longer exist but have been replaced with other content, setting up a 301 redirectis the best solution. A 301 redirect tells search engines and users that the old page has permanently moved to a new location.
Remove the Link: If the linked content is no longer relevant and you cannot replace it, simply remove the broken link.
2. Fix External Broken Links
Contact the Website Owner: If you’ve identified broken external links pointing to your site, reach out to the website owner and ask them to update the link to a valid one. Be polite and provide the correct link so they can quickly make the change.
Use Redirects for Moved Content: If the external website linked to a specific page that no longer exists on your site, implement a 301 redirect to an updated page with similar content.
Disavow Harmful Backlinks: If you encounter external links that are low-quality or spammy and lead to broken pages, consider disavowing them using Google Search Console. This prevents these links from negatively impacting your SEO.
Best Practices for Preventing Broken Links in the Future
Once you’ve fixed your broken links, it's important to implement strategies to prevent them from appearing again. Here are some best practices:
1. Regular Site Audits
Perform regular website audits using SEO tools like Screaming Frog or Ahrefs to identify any new broken links as they appear. Set a schedule to audit your site every few months to keep it in good shape.
2. Set Up Proper Redirects
Always set up 301 redirects when moving or deleting pages. This ensures that visitors and search engines are automatically directed to the right page, rather than encountering a 404 error.
3. Monitor External Links
Keep track of external backlinks to your website. Regularly check for any links that have changed or are leading to 404 errors. Maintaining a relationship with those who link to your content can help you stay on top of link updates.
4. Use Link Management Plugins
If you use WordPress or another content management system (CMS), consider using plugins like Broken Link Checker or Redirection to automatically detect and fix broken links on your site.
5. Avoid Link Overload
Avoid having too many links on a single page, especially external links. Too many external links increase the chances of one of them becoming broken. Keep your internal linking structure tight and organized.
Conclusion: Fixing Broken Links for Improved SEO
Broken links can cause significant harm to both user experience and SEO. Regularly checking and fixing broken links ensures that your website is functioning properly, which can improve your search rankings, enhance user engagement, and increase your website’s credibility. By using the right tools and best practices, you can efficiently identify and resolve broken links and maintain a high-quality, well-optimized website.
