A redirect is a web technique that automatically sends users from one URL to another. This is often used when a webpage has moved to a new address or when a website is reorganized. Redirects help maintain user experience by ensuring that visitors can still access content even if the original link is outdated. There are different types of redirects, such as 301 redirects for permanent changes and 302 redirects for temporary ones. Search engines like Google recognize these redirects, which helps preserve the website's search ranking and ensures that users find the information they need without encountering broken links.
