HTTP Basics
What is an HTTP status code?
An HTTP status code is a three-digit response returned by a web server after a browser, search engine crawler, or other client requests a URL. It tells the requester whether the page loaded successfully, redirected somewhere else, could not be found, or encountered a server problem.
Checking HTTP responses is an important part of technical SEO because search engines need clear signals about which URLs are available, which have moved, and which should no longer be accessed.
Understanding HTTP status code groups
HTTP responses are grouped into categories based on their first digit. These categories make it easier to understand how a server handled a request.
3xx
Redirect responses
A 3xx status means the requested URL redirects to another location. Common examples include 301 permanent redirects and 302 temporary redirects.
4xx
Client errors
A 4xx status usually means the requested resource cannot be accessed. A 404 response, for example, means the page was not found.
5xx
Server errors
A 5xx response means the server encountered a problem while processing the request. These errors can prevent users and search engines from accessing a page.
Common HTTP status codes for SEO
Some response codes appear frequently during technical SEO audits. Understanding what they mean can help you identify broken links, incorrect redirects, unavailable pages, and server problems.
200
OK
The page loaded successfully and is generally available to users and search engines.
301
Moved Permanently
The URL permanently redirects to a different location. This is commonly used when pages or domains are permanently moved.
302
Found / Temporary Redirect
The URL temporarily redirects elsewhere. Search engines may continue to keep the original URL in their index.
404
Not Found
The requested page does not exist at this URL. Broken internal links and outdated URLs frequently return this response.
410
Gone
The page has been intentionally and permanently removed and is not expected to return.
500
Internal Server Error
The server encountered an unexpected problem and could not complete the request.
503
Service Unavailable
The server is temporarily unavailable, often because of maintenance, overload, or another temporary issue.
Why HTTP status codes matter for SEO
Crawlability
Search engines rely on HTTP responses to determine whether they can access and crawl a page successfully.
Redirect management
Correct redirects help search engines understand when content has moved and which URL should be treated as the destination.
Broken URL detection
Finding 404 and server errors helps you repair broken links and improve the experience for both users and crawlers.

Frequently asked questions
What is an HTTP status code?
An HTTP status code is a three-digit response sent by a web server after a browser, crawler, or other client requests a URL. It indicates whether the request succeeded, redirected, failed, or encountered a server problem.
Why do HTTP status codes matter for SEO?
Search engines use HTTP responses to understand whether pages are available, redirected, missing, or temporarily unavailable. Incorrect status codes can waste crawl resources, create broken links, or prevent important pages from being indexed correctly.
What status code should a normal webpage return?
A normal accessible webpage should usually return 200 OK. If the page has permanently moved, a 301 redirect is generally more appropriate.
Is a 301 redirect bad for SEO?
No. A correctly implemented 301 redirect is the standard way to tell browsers and search engines that a URL has permanently moved to another location.
What is the difference between 404 and 410?
A 404 means the requested resource was not found, while a 410 explicitly indicates that the resource has been permanently removed.
