google analytics - multiple trackers on one page (cookie conflict)

Question

I\'m writing a web application that\'s supposed to be embedded in other people\'s websites (kind of a widget). I\'m using Google Analytics to track all the people that visit

Answer 1

This person is having the same problem on the Google Analytics help fourm. I'd suggest taking a look at the thread. But regularly GA doesn't support multiple trackers.

I like Clicky myself, but it costs money.

Answer 2

According to the documentation listed by Török, it seems the correct answer is to use _setCookiePath. This causes each tracker to use completely different cookies.

Example code from website:

<script type=”text/javascript”>
    var pageTracker = _gat._getTracker(”UA-11111-1″);

    pageTracker._setDomainName(’domain.com’);

    pageTracker._setCookiePath(’/subdirectory/’);
    pageTracker._trackPageview();

    var otherTracker = _gat._getTracker(”UA-22222-1″);
    otherTracker._setDomainName(’domain.com’);
    otherTracker._trackPageview();
</script>

When you link from one domain to another, every link that posts to the other domain has to look like this:

<a href="pageTracker._linkByPost('otherdomain.com/petStoreCart/legalTerms.php');"

This will add Google Analytics specific query string values that will be used by the above script to set the cookie (source).

Answer 3

I have used this structure on our site and clients sites and it works like a charm...

<script type="text/javascript"> 
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");    
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js'     type='text/javascript'%3E%3C/script%3E")); 
</script> <script type="text/javascript"> 

try {

//Original tracking
var pageTracker_ORIG = _gat._getTracker("UA-XXXXXXX-1");
pageTracker_ORIG._setDomainName('.sleepinggiantmedia.co.uk');
pageTracker_ORIG._trackPageview();

//New Analytics tag
var pageTracker_SGM = _gat._getTracker("UA-XXXXXXX-1");
pageTracker_SGM._setDomainName('.sleepinggiantmedia.co.uk');
pageTracker_SGM._trackPageview();


} catch(err) {}
