To add Google Analytics or Google Tag Manager to your site, go to Genesis > Theme Settings. Enter the <script> code provided by Google in the Header Scripts or Footer Scripts section, depending on which location is recommended (usually the Header).
You may enter multiple Analytics script tags, if your site is part of more than one organization. You may also use the Header and Footer Script areas to enter verification codes, tracking codes from other analytics services, or any other service that asks you to place a given code block into your site’s <head> tag.
