Redirecting from Blogger with JavaScript
While it’s possible to redirect a whole site from Blogger to the exact same URLs, redirecting to similar URLs is hard.
Let’s say you want to redirect:
from: https://yoursite.blogspot.com/2012/01/blogpost-name.html to: https://newsite.com/blogpost-name The way to do this is to drop a snippet of JavaScript into your Blogger site’s template. Adding a redirect like this also makes it impossible for you to view your blog, so be careful :-). Also, adding a redirect like this means you won’t be able to edit your site’s theme using the simple tools (you’ll need to edit the HTML) - usually that’s no big deal since you want the old site to disappear, right?
