The 404 error page is one of the best-known HTTP status codes, appearing when a page on the internet doesn’t exist or isn’t working. A 404 page is not only a common part of websites, but also an important element of user experience. This article focuses on the meaning of the 404 error code, its history, how to design and manage it effectively, and how to avoid its negative impact on SEO and overall site traffic.

What is a 404 error page?

A 404 error page is an HTTP status code displayed when the server can’t find the requested page. This page is commonly known as “Page Not Found” and informs users that the URL entered doesn’t exist or has been removed.

Explanation of the HTTP 404 status code

• The 404 code is part of HTTP and defines how the server communicates with a web browser. When the server can’t find a page, it returns a 404 code along with a corresponding error page to inform the user of the problem.
• It’s important to distinguish the 404 code from other status codes, such as 401 (unauthorized) or 500 (internal server error), which have different meanings and purposes.

History and significance of the 404 error page

• The 404 code was introduced along with HTTP/1.0 in 1996. At the time, the internet was in its early stages and, although websites were mostly static, error codes already played an important role in communication between the server and the user’s browser.
• The name “404 Not Found” was chosen to clearly tell the user that the requested page isn’t on the server. The number “404” was assigned as part of the standard in which numbers from 400 to 417 indicate client errors.
• In the early internet, a 404 page was usually just simple text. Today, it’s common for websites to use customized, visually appealing error pages that help keep visitors on the site and offer alternative navigation.

The impact of 404 errors on SEO and user experience

A 404 error page is important for both user experience and the technical side of a website. Proper configuration can significantly affect visitor satisfaction and overall impressions.

Ways to improve a 404 page
