What are Page Status Codes and Their Meanings

In the world of websites and search engine optimization (SEO), understanding page status codes is crucial. When you visit a website, the server sends a response to your browser with a status code that indicates the outcome of the request. These status codes provide important information about the success or failure of a web page request. In this article, we will delve into the meaning of various page status codes and explore their significance for SEO.

Definition of Status Codes:

Page status codes, also known as HTTP status codes, are three-digit numbers that represent the response from a web server. They communicate whether the requested page is accessible, redirected, or unavailable. Each status code carries a specific meaning, helping browsers and search engines understand how to handle the requested page.

Common Status Codes:

2.1 200 OK:

The 200 OK status code is the most common response code when a web page request is successful. It indicates that the server has successfully processed the request, and the requested content is being returned to the browser. This status code is an indication of a healthy and accessible web page.

2.2 301 Moved Permanently:

The 301 status code is used when a requested URL has permanently moved to a new location. It is often employed when a website has undergone a domain change or when pages have been moved to new URLs. Search engines understand this code and update their indexes accordingly, transferring the ranking and authority of the old URL to the new one.

2.3 404 Not Found:

The 404 status code is perhaps the most familiar to internet users. It signifies that the requested page cannot be found on the server. This could be due to a mistyped URL, a broken link, or the removal of the page. From an SEO perspective, encountering too many 404 errors can negatively impact a website’s rankings and user experience.

2.4 500 Internal Server Error:

The 500 status code is a generic error response indicating that something unexpected has gone wrong on the server. This could be due to misconfigurations, coding errors, or issues with the server’s resources. When search engine bots encounter this code, they may temporarily or permanently devalue the affected page.

SEO Importance of Status Codes:

Understanding the implications of status codes is crucial for effective SEO. Search engines rely on status codes to determine the accessibility, relevance, and quality of web pages. Pages returning a 200 OK status code are considered healthy and accessible, contributing positively to search rankings. On the other hand, encountering too many errors like 404 or 500 can lead to poor user experience and a negative impact on search visibility.

Best Practices:

To ensure optimal SEO performance, it is important to follow some best practices related to status codes.

4.1 Handling Status Codes Correctly:

Website owners and developers should ensure that the appropriate status codes are returned based on the situation. Pages that have moved permanently should return a 301 code, while inaccessible pages should return a 404 code. Providing accurate status codes helps search engines understand the website structure and ensures proper indexing.

4.2 Redirects:

Redirects play a crucial role in preserving search engine rankings and maintaining a seamless user experience. Proper implementation of redirects, such as 301 redirects, ensures that users are automatically redirected to the new location of a page. This prevents broken links and loss of traffic.

4.3 Error Pages:

Custom error pages can be created to enhance the user experience when encountering 404 or other error codes. These pages can provide helpful information, suggest alternative resources, or guide users back to the main website. Customized error pages can help retain visitors and minimize the negative impact of errors on SEO.


Page status codes are essential elements of website communication, allowing servers, browsers, and search engines to understand the success or failure of a web page request. By familiarizing yourself with common status codes and their meanings, you can optimize your website for better SEO performance. Providing accurate status codes, handling redirects correctly, and creating custom error pages are crucial steps toward maintaining a healthy website and enhancing user experience.
