You can use that embed code in your personal blog where you want your badge to appear.
Generally for blogger and word-press platform you can add it via widgets or plugin.
If you have a wordpress or any other blogging account. Open it and go to your previous posted blogs. For wordpress, upon selecting edit option, you could see the text and HTML tabs at top. Go to HTLM tab and paste the link at top. When you switch back to text, you could see the badge. then publish the blog, same process for new blogs. Very simple!
