HTTP Status Codes are vital for SEO and play a key role in how search engines and users interact with your website. In this guide, we will explain what these codes mean, how they impact your site’s performance, and why keeping an eye on them is important for a healthy SEO strategy.
What Are HTTP Status Codes?
HTTP Status Codes are messages that your server sends when a browser or search engine visits your website. They tell the visitor if the page loaded successfully, was redirected, or encountered an error. Search engines use these codes to decide how to rank your pages and whether to show them in search results. Making sure your pages return the right status codes is a simple yet essential part of technical SEO.
2XX Success Codes
When a page is working as expected, it returns a 2XX code. These codes indicate that everything is okay and that the request was successful. Common codes in this group include:
- 200: This is the standard code that means your page has loaded correctly. It is the most common response and is seen as a positive signal by search engines.
- 201: This code is used when a new page or resource has been created. While not as common for everyday web pages, it is useful when new content is being added.
- 204: This code means that the request was successful, but there is no content to display. It can be useful in API responses or when a page does not need to show any content.
- Using these codes correctly helps ensure that search engines understand your site is functioning properly.
3XX Redirection Codes
Redirection codes come into play when a page has moved from its original location. They are important for preserving link value and ensuring a smooth user experience. The most common 3XX codes are:
- 301 Moved Permanently: This tells browsers and search engines that a page has permanently moved to a new URL. It passes most of the original page’s ranking signals to the new page.
- 302 Found (Temporary): This code is used when a page is temporarily located at a different URL. Search engines usually continue to index the original URL.
- 304 Not Modified: This code indicates that the page has not changed since the last request. It helps save bandwidth and speed up loading times by telling the browser to use the cached version.
Proper use of redirection codes is essential to prevent broken links and loss of traffic during site changes.
4XX Client Error Codes
Client error codes indicate that there is a problem with the request from the user’s end. They often point out issues such as a mistyped URL or a missing page. Some important 4XX codes include:
- 400 Bad Request: This code means the request was not understood by the server. It can be due to a malformed URL or request syntax.
- 401 Unauthorized: This indicates that the page requires a login. If users or search engines hit this code, they cannot access the content.
- 403 Forbidden: When this code appears, it means that access to the page is denied even if credentials are provided.
- 404 Not Found: This is one of the most well-known error codes. It appears when the requested page does not exist on the server. Frequent 404 errors can harm your site’s user experience and SEO if not fixed.
- 410 Gone: This code shows that a page has been permanently removed and is not coming back. It is more definitive than a 404 error.
Monitoring and fixing 4XX errors is a crucial part of SEO. Regularly checking for broken links and missing pages helps maintain a good user experience and preserves your site’s ranking.
5XX Server Error Codes
Server errors occur when there is a problem on the website’s end. These errors indicate that the server failed to fulfill a valid request from the user. Key 5XX error codes are:
- 500 International Server Error: Although usually referred to as the “Internal Server Error,” this code signifies a problem within the server that prevents the page from loading correctly.
- 502 Bad Gateway: This error happens when a server acting as a gateway receives an invalid response from an upstream server.
- 503 Services Unavailable: This code is used when the server is temporarily overloaded or under maintenance. It is often seen during high traffic periods or scheduled downtime.
- 504 Gateway Timeout: This indicates that a server acting as a gateway did not receive a timely response from the upstream server.
Server errors can have a significant impact on SEO as they prevent search engines from indexing your pages correctly. It is important to resolve these issues quickly to avoid losing traffic and rankings.
Additional Errors
In some cases, you might encounter errors like the “Error Establishment Database.” Although less common, these errors indicate issues with database connections. They can affect the entire site’s performance and need immediate attention to ensure that all pages load properly.

- Fix Broken Links: When a 404 error appears, update or redirect the link to a relevant page to maintain a good user experience.

HTTP Status Codes play an essential role in the overall performance and health of your website. They inform both users and search engines about the status of your pages, and managing them well is a key part of any SEO strategy. Whether it’s ensuring your pages return a 200 OK, setting up proper 301 redirects, or fixing pesky 404 errors, each code tells a part of the story of your site’s reliability and quality.
By regularly monitoring and addressing these codes using the right technical SEO tools, you can keep your website running smoothly and maintain a strong position in search engine rankings.
