Pick a button style and copy the code from the Embed Button page.

There are several places you can add the button in your theme. I'll add it just below each post.
On your Blogger dashboard, click 'Template' in the dropdown.
Click 'Edit HTML' to open up the theme editor.
Find "<b:if cond='data:blog.metaDescription == ""'>" in the editor. You can edit the post template here.
Paste the button HTML just below that tag.
Save it, and you're done! Open up a post on your Blogger blog and you'll see the button below the post.
