301 Redirect, 302 Redirect, Meta Refresh Redirect
A page setup to redirect a visitor automatically to another page. There are several methods of setting up a redirect and what you use depends on what you want to serve to the visitor and search engines.
A 301 Redirect is a permanent redirection that automatically sends a visitor to a new page. A search engine bot will ignore the content of the redirect page, indexing and ranking the new page (some link juice can is lost in this process).
A 302 Redirect is a temporary redirection that you can use for temporarily moved content.
A Meta-refresh Redirect is not strictly a redirect and should only be used if a 301 Redirect is not available. It is a small line of code in the header of a page that tells the browser to refresh after a period of time (set to zero for an immediate refresh) and can include a new URL to display (the redirect).
