We think it’s best that certain aspects of your site don’t change when you change themes. As a result, none of our themes offer a Google Analytics field. For this, we recommend using a plugin. The below recommendations assume you already have an account setup with Google Analytics.
Google Analytics by Yoast. To install this plugin navigate to PluginsAdd New and use the search field to search for Google Analytics Yoast. Once installed you’ll find it under Dashboard with the menu label, Analytics. There you can authenticate your Google account or enter your UA code manually.
