Redirects: A redirect is a technique used to automatically send a website visitor from one URL (webpage) to another, often due to changes in the website's structure or to direct users to a new or updated page. Redirects are essential for maintaining a good user experience and preserving your site's SEO rankings when webpages are moved or deleted. There are several types of redirects, such as 301 (permanent), 302 (temporary), and 404 (page not found) redirects.
