GatherKit simplifies the management of URL slugs, both new and old, in a way that doesn’t overwhelm your client. It provides a simple and organized system to keep track of all your redirects effectively.
In your Kit, click on Developer in the sidebar.
Click on URL Redirects. (Keep in mind, this list will be auto-populated from your Pages.) Within each row, you can add content to the new slug and old slug(s). It will autosave accordingly.
If you need to save or share this URL redirect list, you can always click the EXPORT button in the top right corner to save.
