2xx status codes are HTTP response codes that indicate a successful request. When a web browser or search engine crawler sends a request to a server, the server responds with one of several status codes, and those in the 2xx category confirm that the requested resource has been successfully retrieved or processed.
The most common 2xx code is 200 OK, which signifies that the server has successfully fulfilled the request and returned the requested content. This ensures that both users and search engines can access your website’s pages without issues. Other notable 2xx codes include 201 Created, indicating that a new resource has been created as a result of the request, and 204 No Content, which means that while the request was successful, there is no content to return.
