An example of the page where we are:
(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', '//www.google-analytics.com/analytics.js', 'ga');
ga('create', 'UA-5620270-42');
ga('set', 'dimension1', '2604985');
ga('set', 'dimension2', '|google|');
ga('send', 'pageview');
Common things in these scripts that have different generations / versions is the client key, in this case UA-5620270-42
and the ga
variable that I can remember as much as I remember in all variants.
