Add Google Analytics Tracking Code to your Theme

Adding tracking code, scripts or other custom code before the </head> or </body> tags in your theme is very simple.
Navigate to Theme Options → Miscellaneous → Custom Code and insert your Analytics tracking code (not just your Tracking ID) in one of the two available locations: Header or Footer, depending on instructions you have received.

Optionally you can use a 3rd party like Google Analytics for WordPress to add your tracking code to your site, and be sure that it will remain on your site even when you’re switching to a different theme.
