pagespeed UseAnalyticsJs off with Experiments

[Rene Molenaar]

Hi all,

I have a simple pagespeed Experiments  config that I'm testing:

pagespeed RunExperiment on;

pagespeed UseAnalyticsJs off; # use GA.js, is slower

pagespeed ExperimentVariable 1;

pagespeed EnableFilters insert_ga;

pagespeed AnalyticsID UA-XXXXXXX-X;

pagespeed ExperimentSpec "id=1;percent=50;default";

pagespeed ExperimentSpec "id=2;percent=50";

The configuration above works, I can see my cookies and the inserted javascript: _gaq.push(['_setCustomVar'

From what I've read here:

https://developers.google.com/speed/pagespeed/module/module-run-experiment

It sounds better to get rid of "pagespeed UseAnalyticsJs off;" so that we use analytics.js instead of ga.js.

However, when I do this, I don't see Javascript _qaq.push anymore in my HTML pages. Anything I'm missing?

analytics.js doesn't support setting custom variables, so you;d also
have to switch to running a google analytics "content experiment":
