Redirect – SEO WIKI
A redirect is the redirection of users from one site to another, which is carried out automatically.
A redirect occurs when the user types one address in the address bar, and gets to the site with a different address.
Also, a redirect is understood as a script during which a web browser redirects users to another web resource. It is used mainly when the site changes the address. In order not to lose regular customers, they resort to a redirect, in which there is a redirect from the old address to the new one.
There is a 301 redirect, which is implemented at the server level of the search engine.
