Fast online service for checking the server response code (advanced mode). If the requested URL performs a 301, 302, 303, or 307 redirect, then up to 5 redirects are allowed during validation. To check, you can specify two methods HEAD or GET, in the latter case, the html code of the document will be displayed.

When requesting a document with an If-Modified-Since or If-None-Match header, the client (User-agent) passes the date. In the case when the content of the page has not changed since the specified date, a properly configured server should return a 304 Not Modified response and not contain the document body. If the document has changed since the requested date, the server returns a 200 Ok response.

Checking the server response code for a website is an important aspect of website monitoring and maintenance. When a user requests a website, the web server responds with a status code that indicates whether the request was successful or not. The status code is a three-digit number that is included in the HTTP response header.

There are several types of status codes, but the most common and important for SEO are:

  • 200 OK – The request was successful and the server is returning the requested information.
  • 301 Moved Permanently – The requested URL has been permanently moved to a new location.
  • 302 Found – The requested URL has been a temporary redirection of a URL to a new location.
  • 304 Not Modified – The requested resource has not been modified since the last time it was accessed by the client.
  • 403 Forbidden – The server is denying access to the resource requested by the client.
  • 404 Not Found – The requested URL was not found on the server.
  • 410 Gone – A web page has been intentionally removed or deleted, and the server wants to inform the client that the resource is gone for good.
  • 500 Internal Server Error - The server encountered an error while processing the request.

When you check the server response code for a website, you can quickly identify any issues with the website's server or network. This can help you to troubleshoot and fix any problems before they impact your website's performance or user experience.
