Adding Analytics and Social Buttons to Website

You can add this in the Website Settings under "Startup Code"

Google Analytics

Remember to set your correct account id

window._gaq = window._gaq || [];
window._gaq.push(['_setAccount', 'UA-XXXXXXX']);
window._gaq.push(['_trackPageview']);

(function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') 
        + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

Twitter Badges

In the startup section, add this:

(function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];
if(!d.getElementById(id)){js=d.createElement(s);js.id=id;
js.src="//platform.twitter.com/widgets.js";
fjs.parentNode.insertBefore(js,fjs);}})(document,"script","twitter-wjs");

In the page, in the onload method (in the code section) where you want your badge to appear:

wn.pages["page-name"].onload = function(wrapper) {
    // render twitter button
    window.twttr && window.twttr.widgets && window.twttr.widgets.load();
}

Google Plus One

Add this in the "Startup" section in Website Settings

(function() {
    var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true;
    po.src = 'https://apis.google.com/js/plusone.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s);
})();

In your page (make sure to set your page name):

wn.pages["page-name"].onload = function(wrapper) {
  // render plusone
  window.gapi && window.gapi.plusone && window.gapi.plusone.go();
}
