404sivua

404sivua is the Finnish term for a 404 error page, the web page shown when a requested resource cannot be found on the server. It is typically delivered with the HTTP status code 404, though some configurations may return a different status. The purpose of a 404sivua is to inform the user and offer navigation options.

The word 404 comes from the standard error code, and sivua means page in Finnish. Together, 404sivua is commonly used by Finnish web developers to refer to the error page concept in documentation and UI design.

A typical 404sivua includes a brief apology and a concise explanation that the requested URL could not be found. It often provides practical navigation, such as a link to the homepage, a site search, or access to popular pages and a site map. Some sites personalize the message with branding or humor, while others keep a neutral design. Accessibility and responsiveness are common goals.

Usage and impact: 404sivua helps retain visitors by offering alternatives instead of leaving them stranded. It signals administrators to check for broken links and missing resources. For search engines, a proper 404 response indicates a not-found resource; managers should avoid soft 404s and implement proper redirects when appropriate.

In Finnish web development, 404sivua is treated as a standard usability element. Many content management systems provide built-in templates that can be customized to match site branding, language, and user expectations.
