All the incoming traffic from the old post URL would vanish, instead it will show up a 404 page error on your blog. That's not better for your visitors, blog and also in terms of SEO. The simple solution is to use permanent redirection from old Blogger post URL to new post URL. You can find custom redirect setting into your Blogger dashboard. I will discuss it later.
