Hola Enrique,
nosotros colocamos el script de Google Analytics en el siguiente fichero: alfresco-template.ftl que está en la ruta tomcat\webapps\share\WEB-INF\classes\alfresco\templates\org\alfresco\include entre las siguientes líneas:
<script type="text/javascript">//<![CDATA[
Alfresco.util.YUILoaderHelper.loadComponents(true);
<#-- Security - ensure user has a currently authenticated Session when viewing a user auth page e.g. when Back button is used -->
<#if page?? && (page.authentication="user" || page.authentication="admin")>
Alfresco.util.Ajax.jsonGet({
url: Alfresco.constants.URL_CONTEXT + "service/modules/authenticated?noCache=" + new Date().getTime() + "&a=${page.authentication?html}"
});
</#if>
//]]>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'XX-XXXXXX-X', 'auto');
ga('send', 'pageview');
</script>
Espero te sirva.
¡Un saludo!
Jorge
