WordPress 404 Errors Impact On-Site Performance and Tip for Simple Fixes

When your browser sends a request to the server, a data file called ‘HTTP header’ is returned. It holds an HTTP status code, which explains the status of your request. These requests work just fine almost all the times, and the HTTP status code is not displayed on the browsers. If something is not correct, then the browser displays HTTP status code indicating a specific issue. 

Generally, a 404 error means the browser succeeded in connecting with the server but could not find the requested URL. Besides posts and pages, a missing asset [Javascript or CSS or image file] generates 404 server errors.
