Add Redirect or Marketing URL

For existing pages, create a redirect for both the page alias and the node/id. To get the node/id, navigate to the page, and click on the Edit tab. You will see the node id in the url bar of your browser. In this case it is node/6221

In the top toolbar, go to Configuration > Search and meta data > URL redirects > Add redirect

Configuration > Search and meta data > URL Redirects > Add redirect

 

First, add the redirect for the page alias (existing url of the page).
create redirect by adding existing path and the redirect

Then create the alias for the node id. You can use relative or full paths in the "To" (destination) field.
insert the node id in the path field, and the destination url in the to field

For marketing urls, you can create a redirect using the same method above. Since the marketing url itself is not associated with a specific node id, you just need to follow the aliased path method using the preferred marketing slug as the Path.
