To add a Facebook badge to your WordPress-powered site, you’ll need to make a badge on Facebook itself.

On Facebook:

1. Go here: http://www.facebook.com/facebook-widgets/ and choose the type you want. (Profile badge is used often).
2. When it asks what type of code you need, choose “other” — it will give you an area of code to copy/paste.

Go To Your Site:

• Log in to the backend of your site.
  
• Once you’re at the dashboard, click on widgets on the right hand side — that’s where the sidebar features are.
• Choose a “text” widget, drag it to the right side of the screen.
• When it opens, paste the code into the text box.
• Then hit save and it will appear on your sidebar.
