The Ultimate Guide on How to Fix the 404 Not Found

What does the error 404 not found mean?

The error 404 not found is a common HTTP status code that indicates the requested web page or resource could not be found on the server. This means that the server was able to communicate with the client, but it could not locate the specific file or page that the client requested.

The 404 error can occur for a variety of reasons, such as:

• The page or resource has been moved or deleted from the server.
• The URL or link provided to the client is incorrect or broken.
• The web server is experiencing technical issues and cannot locate the requested resource.
• The website’s content management system or web application is not configured correctly.

Understanding the meaning and common causes of the 404 error is the first step in troubleshooting and resolving this issue.

Common causes of the error 404 not found

There are several common reasons why the 404 error not found may occur on a website:

1. Broken or incorrect links: When a web page or resource is moved or deleted, the links pointing to that content become broken, leading to a 404 error.
2. Outdated or expired content: If a website’s content is not regularly updated or maintained, old pages or resources may become obsolete and result in 404 errors.
3. Misconfigured web server: Issues with the web server’s configuration, such as incorrect file paths or directory settings, can prevent the server from locating the requested resource.
4. Content management system (CMS) issues: Poorly configured or outdated CMS platforms can sometimes generate 404 errors, especially when pages or posts are deleted or moved.
5. Third-party integrations: If a website relies on external services or APIs, any issues with those integrations can also lead to 404 errors.
6. Hacking or security breaches: In some cases, a 404 error may be the result of a security breach or hacking attempt, where the attacker has removed or hidden specific content.

Understanding these common causes can help you better diagnose and address the 404 error on your website.

Impact of the error 404 not found on website performance

The error 404 not found can have a significant impact on a website’s performance and user experience. Some of the key impacts include:

1. Decreased user satisfaction: When users encounter a 404 error, they are unable to access the content they were looking for, leading to frustration and a negative perception of the website.
2. Increased bounce rates: High 404 error rates can cause users to leave the website quickly, resulting in increased bounce rates and decreased engagement.
3. Reduced search engine visibility: Search engines may penalize websites with high 404 error rates, as it can be an indicator of poor website maintenance and content management.
4. Wasted server resources: Each 404 error request still requires the web server to process the request, leading to unnecessary resource consumption and potential performance degradation.
5. Damaged brand reputation: Frequent 404 errors can create the impression of a poorly maintained or unprofessional website, which can negatively impact a brand’s reputation and credibility.

Addressing and resolving 404 errors is crucial for maintaining a positive user experience, improving website performance, and preserving a brand’s online reputation.

Troubleshooting the 404 error not found involves a systematic approach to identify the root cause and implement the appropriate solution. Here are the steps to follow:

1. Identify the specific 404 error: Determine the exact URL or resource that is generating the 404 error. This information can be obtained from the website’s error logs, analytics, or by directly testing the problematic URL.
2. Investigate the cause: Analyze the circumstances surrounding the 404 error, such as recent website changes, server configuration updates, or any third-party integrations that may have been affected.
3. Check for broken links: Conduct a comprehensive audit of the website’s internal and external links to identify any broken or outdated links that may be causing the 404 error.
