Redirects are techniques used in web development to automatically send visitors and search engines from one URL to another. The two most common types are 301 and 302 redirects. A 301 redirect is a permanent redirection, indicating that a page has moved to a new location for good. This type passes most of the original page s SEO value to the new URL. A 302 redirect is temporary, signaling that the move is not permanent and the original URL may be used again in the future. Proper use of redirects helps maintain user experience and preserves search engine rankings when URLs change.
