Redirection is the process of forwarding both users and search engines from a URL of web page to a different URL on another site or server. 301 redirects are particularly useful, if you've moved your site to a new domain, and you want to make the transition as seamless as possible. This is the best way to ensure that users and search engines are directed to the correct page. When doing this, it is critical to observe best practices in order to maintain SEO value.
