Cannot Modify After Publishing : Once a post is published , you cannot change its permalink. If you need to change the URL after publishing, you would have to either: Recreate the post : Copy the content, delete the old post, and publish it as a new post with the desired permalink. Redirect old links : Unfortunately, Blogger doesn’t have built-in redirection, so if you change the post URL by republishing, you’ll lose the traffic from the original URL unless you manage redirection using external tools.
