Understanding 404 Not Found Errors and How to Fix Them Effectively

What is 404 Not Found?

404 Not Found is an HTTP status code returned by the server when a browser sends a request to access a webpage, but the server cannot find the page. This is a common error encountered while browsing, indicating that the content or resource the user is looking for does not exist at the requested URL.

Examples of 404 error messages:

• "404 Error: Page Not Found"
• "The requested URL was not found on this server."
• "We can’t seem to find the page you’re looking for."

404 errors not only impact user experience but also negatively affect SEO if not addressed promptly. Let’s explore the causes of this error and effective ways to fix it in the following sections.

Causes of 404 Not Found Errors

404 Not Found errors can occur for various reasons, ranging from technical issues on the website to user-related mistakes. Below are some common causes:

• Incorrect URL entry: Users may accidentally mistype or add incorrect characters to the URL.
• Broken links: Links that lead to pages that no longer exist or have been deleted.
• Deleted or moved pages: Content that has been deleted or moved to a different URL without setting up a 301 redirect to notify search engines and users.
• Expired domain: Websites that are no longer active because the domain has not been renewed.
• Server configuration errors: The server fails to process the request due to misconfigurations.
• URL structure changes: When a website changes its URL structure (e.g., switching from www to non-www) without updating internal links or creating appropriate redirects.

Identifying the root cause is the first step toward effectively resolving 404 Not Found errors. In the next section, we’ll explore the consequences of these errors.

How 404 Not Found Errors Impact Your Website

404 Not Found errors can have significant negative consequences for both users and website owners, including:

Impact on User Experience

Users often feel frustrated when they cannot access the content they’re looking for, leading to a loss of trust in the website. This is especially critical for e-commerce websites, where customers may abandon their purchases due to missing product pages.

Increase in Bounce Rate

When users encounter a 404 error, they typically leave the website immediately, causing the bounce rate to rise. A high bounce rate sends negative signals to search engines that your website is not delivering value.

Negative SEO Impacts

• Lower rankings: Google penalizes websites with frequent 404 errors, impacting the overall ranking of the website.
• Traffic loss: Links from search results that lead to 404 errors reduce organic traffic to your site.

Lost Business Opportunities

Each 404 error represents a missed opportunity to convert users into customers or increase engagement. This directly affects revenue and business goals.

Damage to Website Reputation

Frequent 404 errors can make users question the professionalism and reliability of your website, diminishing brand credibility.

11 Effective Ways to Fix 404 Errors

404 Not Found errors can significantly harm user experience and your website’s SEO rankings. It’s crucial to address them promptly. Here are 11 effective ways to fix 404 errors:

Refresh the Page

Sometimes, a 404 error occurs due to temporary server issues or an unstable internet connection. Simply refreshing the page by pressing F5 or clicking the refresh button on your browser can resolve the problem.

Clear Browser Cache and Cookies

404 errors may also result from outdated information stored in the browser cache. Clear your cache and cookies to ensure the browser is loading the latest version of the website.

• How to do it:
  • Go to your browser’s Settings.
  • Find the Clear browsing data section and select Cache and Cookies to delete them.

Verify and Re-enter the URL

Minor typos in the URL are a common cause of 404 errors. Double-check the URL you entered to ensure there are no spelling mistakes, missing characters, or unnecessary spaces.

Search for the URL Using a Search Bar

If the URL does not work, try searching for the content through the website’s search bar or search engines like Google. This can help you locate the correct page or URL.

Change DNS Server

404 errors may sometimes be linked to issues with the DNS server. You can try switching to Google’s DNS (8.8.8.8) or Cloudflare’s DNS (1.1.1.1) to resolve the issue.

• How to change DNS on Windows:
  1. Go to Control Panel > Network and Internet > Network and Sharing Center.
  2. Select your active network and click Properties.
  3. Change the DNS settings to 8.8.8.8 and 8.8.4.4 (Google’s DNS).

Access Cached Versions of the Page Through Google Cache

Google stores backup copies of webpages in its cache. If a page has been deleted, you can still access an older version through Google Cache.

• How to do it:
  • Search for the URL on Google.
  • Click the downward arrow next to the search result and select Cached.

Implement 301 Redirects

If a page has been deleted or its URL has changed, set up a 301 redirect to guide users from the old URL to the new one.

• How to do it:
  • For WordPress: Use the Redirection plugin to create 301 redirects easily.
  • Update the .htaccess file on your server with the redirect code.

Redirect 301 /old-page https://www.example.com/new-page

Access Higher-Level Directories

If the URL for a specific page is broken, try navigating to higher-level directories. For example, if https://example.com/blog/post-name returns a 404 error, access https://example.com/blog to check if the main directory is functional.

Contact Website Administrators or Specialists

If you cannot resolve the 404 error, contact the site administrator or a technical expert for support. They can check server configurations, internal links, and other factors to address the error comprehensively.

Check Internal Links

Some 404 errors may result from internal links pointing to non-existent pages. Audit all internal links to ensure they lead to valid pages.

• How to do it:
  • Use tools like Screaming Frog SEO Spider or Ahrefs Site Audit to scan and identify broken internal links.
  • Update broken links or implement redirects as needed.

Internal links not only affect user experience but are also critical for your SEO strategy.

Update Your XML Sitemap

If certain URLs have been deleted or changed, update your sitemap to ensure Google and other search engines recognize the changes.

• How to do it:
  • For WordPress: Use a plugin like Yoast SEO to automatically update your sitemap.
  • Submit the new sitemap to Google Search Console for faster updates.

Updating your sitemap helps resolve 404 errors and improves the indexing speed of your website on search engines.

These fixes not only help you address 404 errors effectively but also enhance user experience and maintain your website’s SEO performance.

When 404 errors are unavoidable, designing a custom 404 page that is professional and user-friendly is the best way to mitigate their negative impact. A well-designed 404 page not only retains users but also offers an opportunity to guide them to other content on your site.

Keep the Message Friendly and Clear

• "Sorry, we can’t find the page you’re looking for."
• "It seems you’re lost, but don’t worry—we’ll help you find your way!"

Add Navigation Buttons to Important Pages

Include buttons or links that direct users to:

• The homepage.
• Categories or the most popular content.
• A search bar so users can find what they need.

Maintain Design Consistency

Your 404 page should have a consistent design with your website to prevent users from feeling disconnected. Use the same fonts, colors, and logo as your site.

Add Interactive Elements

Use illustrations, icons, or even animations to make the 404 page more friendly and engaging. This can reduce user frustration when encountering errors.

Track 404 Page Performance

Use tools like Google Analytics to monitor:

• The number of users visiting the 404 page.
• Their behavior on the page (leaving or navigating to other content).

Based on collected data, you can improve your 404 page to increase user retention.

Examples of Custom 404 Pages:

• Airbnb: Uses fun illustrations and suggests helpful links.
• Netflix: Keeps the design simple with a clear message and a button to return to the homepage.

A well-designed 404 page not only reduces bounce rates but also enhances user experience and increases the chance of retaining visitors. Ensure that your 404 page is both professional and friendly to turn an issue into an opportunity.
