301 and 302 redirect
When you remove a page or product from your website, it gives No-Page-Found error for that URL because that URL is gone. The server will fetch 404 error (No page found) to the visitors and it will increase the bounce rate as well as negative impact of the ranking of your website on Google and other search engines.
Now, there are two redirects for a gone page.
301 redirects - This is permanent redirection of a gone page to a new URL which is in force.
302 redirects - This is temporary redirection of a gone page to a new URL until the same (gone page) is redesigned or redeveloped. It is generally used in maintenance mode.
