How to Solve 404 Errors on Your Website

The infamous 404 error, or “Page Not Found” error, is one of the most common issues encountered on the internet. While it might seem harmless, repeated 404 errors on your website can negatively impact user experience, SEO rankings, and your overall online credibility. In this comprehensive guide, we’ll explore what causes 404 errors, their impact, and actionable steps to resolve them. Let’s dive in!

What Is a 404 Error?

A 404 error occurs when a user tries to access a webpage that doesn’t exist on your server. Instead of displaying the requested content, the server returns an HTTP 404 status code along with an error message like “404 Not Found” or “Page Not Found.”

Common Variations of the 404 Error Message:

• “404 Page Not Found”
• “HTTP 404”
• “Error 404”
• “The requested URL was not found on this server”

Why Do 404 Errors Occur?

Several factors can cause 404 errors on your website. Common reasons include:

1. Deleted Pages: If a page is removed without proper redirection, users and search engines will encounter a 404 error.
2. Broken Links: Incorrect URLs in internal or external links can lead to non-existent pages.
3. Typographical Errors: Typos in URLs entered by users or linked from other sources.
4. Moved Pages: If a page’s URL structure changes but old URLs are not redirected, 404 errors will occur.
5. Incorrect Domain Names: Typos in the domain name can also trigger 404 errors.
6. Server Configuration Issues: Problems with server settings, such as incorrect .htaccess rules, can cause pages to become inaccessible.
7. CMS Errors: Errors in Content Management System (CMS) settings or plugins can result in broken links.

Why Are 404 Errors a Problem?

404 errors can harm your website in multiple ways, including:

1. Impact on User Experience:

Encountering a 404 page can frustrate users, causing them to leave your site and potentially never return.

2. SEO Consequences:

Search engines like Google view excessive 404 errors as a signal of poor website maintenance. This can:

• Lower your search rankings.
• Reduce crawl efficiency as search engine bots waste time indexing nonexistent pages.

3. Brand Reputation:

Frequent 404 errors can damage your website’s reputation, making it appear unreliable or unprofessional.

4. Lost Conversions:

If users can’t access key pages like product or service information, you risk losing potential customers.

How to Detect 404 Errors

1. Google Search Console:

Google Search Console is one of the best tools for identifying 404 errors. Follow these steps:

• Log in to your account.
• Navigate to the Coverage or Crawl Errors report.
• Review the list of URLs marked as “Not Found.”

2. Analytics Tools:

Use tools like Google Analytics to identify 404 pages that users encounter frequently. Set up a custom report to track pages with the title “404 Error.”

3. Crawling Tools:

Website crawling tools like Screaming Frog, Sitebulb, or SEMrush can scan your site for broken links and missing pages.

4. Manual Checks:

Periodically review your website’s content and links to ensure they lead to the correct destinations.

5. Third-Party Monitoring Services:

Services like Dead Link Checker or Broken Link Checker can help identify and monitor broken links across your website.

How to Fix 404 Errors

Now that you’ve identified the issues, let’s explore solutions to fix them effectively.

1. Set Up 301 Redirects:

A 301 redirect permanently directs users and search engines from the old URL to a new one. Here’s how to implement it:

• Using .htaccess (Apache): Add this code to your .htaccess file:

  Redirect 301 /old-page.html /new-page.html

• Using CMS Plugins: Platforms like WordPress offer plugins (e.g., Redirection, Rank Math) to set up redirects easily.

2. Create a Custom 404 Page:

A custom 404 page improves user experience and guides visitors back to relevant parts of your site. Include:

• A friendly message (“Oops! Page not found.”).
• Links to popular pages or the homepage.
• A search bar.

3. Fix Internal Links:

Review and correct broken internal links. Use tools like Screaming Frog to locate and update these links.

4. Update External Links:

If external sites link to missing pages, reach out to the site owners and request corrections. Alternatively, use 301 redirects.

5. Recreate Missing Pages:

If the missing page was popular or important, consider recreating it with updated content.

6. Monitor for Future Errors:

Set up automated tools or schedule regular checks to detect and resolve new 404 errors promptly.

Best Practices for Preventing 404 Errors

1. Plan URL Structures Carefully:

When designing your website, use logical and consistent URL structures. Avoid unnecessary changes to URLs.

2. Implement Redirects for Removed Pages:

If you delete a page, always set up a 301 redirect to an alternative page.

3. Use an XML Sitemap:

An updated XML sitemap helps search engines find and index your pages correctly. Submit it to Google Search Console and other webmaster tools.

4. Avoid Linking to Nonexistent Pages:

Double-check all links before publishing content to ensure they lead to live pages.

5. Regularly Audit Your Website:

Perform routine audits to identify and fix broken links or missing pages.

6. Enable a Search Functionality:

A search bar allows users to find the information they need, even if they encounter a 404 page.

7. Monitor Backlinks:

Keep an eye on backlinks to your site. Use tools like Ahrefs or Moz to identify and address links pointing to nonexistent pages.
