Implementing A / B test tracking requires updating the Google Analytics script.
The operation consists of entering a custom variable with the value "yes" or "no" depending on whether the page is optimized or not.
Adding the custom variable
Here is the tag to add between _gaq.push(['_setAccount'
and_gaq.push(['trackPageViews']);
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXXXXX-1']);
// Début du code à copier-coller
var cookie = document.cookie;
if (cookie.indexOf('fstrz=') !== -1) {
_gaq.push(['_setCustomVar', 5, 'Fasterize', cookie.indexOf('fstrz=true') !== -1 ? 'yes' : 'no', 2]);
} else {
_gaq.push(['_setCustomVar', 5, 'Fasterize', 'untracked', 2]);
}
_gaq.push(['_setSiteSpeedSampleRate', 100]);
// Fin du code à copier-coller
_gaq.push(['_trackPageview']);
