Google Analytics pageTracker is not defined?

Question

Little bit confused... I am trying to track mailto links being clicked, but constantly 'pageTracker is not defined' is shown. I have the following code just before my end body tag ()

<script type="text/javascript">
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-000000']); // This is my account number, I have added the zeros in this editor
  _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);
  })();
</script>

Then I am using this in my mailto links

<a href="mailto:hello@mydomain.co.uk" onClick="javascript:pageTracker._trackPageview('/mailto/hello');">hello@mydomain.co.uk</a>

I cannot see why its not working? Any help would be appreciated

Answer 1

The new Async Google Analytics code (that you're using) works a bit differently than the non-Async. Any time that you want to call a method on pageTracker you simply push a "message" onto the "_gaq" queue.

<a href="mailto:hello@mydomain.co.uk" onClick="_gaq.push(['_trackPageview', '/mailto/hello'])">hello@mydomain.co.uk</a>

Although, tracking a mailto link may work better as an event:

<a href="mailto:hello@mydomain.co.uk" onClick="_gaq.push(['_trackEvent', 'mailto', 'home'])">hello@mydomain.co.uk</a>

For more info take a look at the Async Tracking Users Guide.

Answer 2

We can also add:

//mantain syntax between old and new asynch methods
//http://code.google.com/apis/analytics/docs/tracking/asyncUsageGuide.html#Syntax
function _pageTracker (type) {
    this.type = type;
    this._trackEvent = function(a,b,c) {
       _gaq.push(['_trackEvent', a, b, c]);
    };
}

var pageTracker = new _pageTracker();

in new code to mantain old code in pages.

Answer 3

Here is the code :

onClick="_gaq.push(['_trackEvent', 'pdf', 'download', '/pdf/myPdf'])">myPdf</a>

Answer 4

I needed a way to tack downloading PDFs too and heres what I used:

<a href="http://www.domain.com/assets/downloads/filename.pdf" target="_blank" onClick="_gaq.push(['_trackEvent', 'Downloads', 'Download', 'Price Brochure PDF'])">Download Brochure</a>

For more info about _trackEvent, heres the API Doc page
