Session and conversion data missing from AdWords campaigns in Analytics

[Evoworks]

Hi all,

For a client of ours, we're not seeing session & conversion data for AdWords campaigns in Analytics. We are seeing click & cost data. Adwords and Analytics are linked and autotagging is enabled.

The site where we're experiencing this problem is www.maxifleur-plantes-artificielles.fr. It's a Magento-based store with the Web Cooking Universal Analytics extension installed. The bulk of AdWords traffic is landing on the page www.maxifleur-plantes-artificielles.fr/plantes-artificielles, which has no active redirects that could remove the ?gclid parameter for as far as I can tell. Yet, click IDs that I manually tested won't show up in the reports either. Mid April, all traffic aside from direct traffic just disappeared from the reports. Google's Tag Assistant gives a lot of errors, but in the source code the snippet looks just fine and we don't have problems with other web shops that use the aforementioned extension.

Suggestions as to what could be the problem are most welcome.

Thanks!

Bas

Thank you for your response. We're going to have to look into that, I think. It's a bit of a hassle, since we're using an extension that works just fine in other shops. In the source code, the ga() is called in a separate

Hi Bas,

You've looked into the JavaScript errors via the console? The first thing I see is that ga() is not initialized in there which could cause a lof of tracking issues.
