A response status code that indicates that a requested resource or page has been permanently moved to a new URL. When a client (such as a web browser) sends a request for a resource or page, the server can respond with a 301 status code and a new URL that the client should use to access the resource or page.
A 301 redirect is often used when a website owner wants to redirect traffic from an old URL to a new URL. This can be useful in situations where a website has been restructured or redesigned, and old URLs are no longer valid. By implementing a 301 redirect, website owners can ensure that users who try to access old URLs are automatically redirected to the new URLs, avoiding 404 errors and ensuring that users can find the content they are looking for.
In addition to redirecting users, a 301 redirect also signals to search engines that a page has permanently moved to a new location. This can help preserve search engine rankings and ensure that users can continue to find the content they are looking for through search engines.
