A 301 redirect denotes a permanent switch from one web page to another. It is a task that needs to be completed before a URL becomes obsolete.
It essentially entails ensuring that when a user types in a non-existent URL, they are automatically directed to another that we have adapted as the destination link.
A 301 redirect is considered permanent in the sense that it indicates that the old URL is no longer valid for whatever reason and that the valid one is the one we have now created.
Simply put, a 301 redirect informs the browser that “this page has been permanently relocated, and this is the new address.”
To which the browser responds, “OK, no problem! I will send the user to the new URL!”
For example, if you apply a 301 redirect to the URL yoursite.com/example-1 indicating that it points to the URL yoursite.com/example-2 when a user or search engine robots access example-1 they will be redirected to the example-2.

When to Do a 301 Redirect?
In most cases, you will do a 301 redirect, since we will need to indicate to Google a suitable architecture in the URLs to improve usability and SEO, and this is done permanently.
In any case, do not waste time in redirecting URLs that contribute little, that did not treat good content or that did not have traffic or links. The best thing in these cases is to let them die.
