Uudelleenohjaus

Uudelleenohjaus, often translated as redirection, is a common technique used in web development and networking to direct users and search engines from one web address (URL) to another. This process is typically handled by the web server, which sends a specific HTTP status code to the browser indicating that the requested resource has moved.

The most common types of uudelleenohjaus are the 301 and 302 redirects. A 301 redirect, known as "Moved Permanently," signals that the original page has been permanently relocated to a new URL. This is crucial for search engine optimization (SEO) as it tells search engines to update their index and transfer any accumulated ranking signals to the new address. A 302 redirect, or "Found" (formerly "Moved Temporarily"), indicates that the move is temporary. In this case, search engines are instructed to continue indexing the original URL, as it is expected to become active again in the future.

Uudelleenohjaus serves several purposes. It helps maintain website usability by ensuring that users who access old or broken links are still directed to relevant content. This prevents them from encountering "404 Not Found" errors. Website restructuring, domain name changes, merging content, and implementing SSL certificates are common scenarios where uudelleenohjaus is employed. Properly configured redirects are vital for a seamless user experience and effective search engine visibility.
