Google Analytics Tracking Code and Actions

In this post I will break down the elements of your Google Analytics Tracking code and cookies.

Your tracking code can be found in your analytics admin under property settings,  It will look similar to this:

<!– Global site tag (gtag.js) – Google Analytics –>
<script async src=”https://www.googletagmanager.com/gtag/js?id=UA-*********-***”></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag(‘js’, new Date());

gtag(‘config’, ‘UA-*******-**’);
</script>

  • Ga uses ga() command queue for various tracking methods including:
  • Create: creates a new tracker instance with the specified fields
  • Send: sends a hit to google analytics
  • Require: dependant on analytics.js plugin
  • Provide: Provides analytics.js plugin and its methods for use with the ga() command queue

Command syntax
Ga(command, […fields],[fieldsObject])
Example: ga(‘create’,’UA-*******-*’,’auto’);

  • GA requires a tracker object for data collections
  • Tracker objects  collect and store data and then send that data to Google Analytics
    • Default implementation creates tracker object by running the following command:
      ga(‘create’,’UA-******-*’,’auto’);
  • This command creats a tracker object by passing “UA-*****-*
    as the Tracking ID and “aucto” for the configured domain name
  • Without setting a specific name for the tracker the defualt tracker is internally given the name “to”
    • To change the tracker object’s name, use the folling command:
      ga(‘create’, ‘UA-*******-*’, ‘ auto’, ‘ TrackerName’);


Configure Cookie and Session

A browser cookie is being used to determine that two or more distinct hits belong to a user

 

 

 

 

 

 

GATC generates a unique randomly generated Client ID and stores it in a first party cookie. By default the cookie name is _ga.   This cookie is allocated to the top level domain and all of its subdomains, other domains require cross-domain tracking.

GATC generated the cookie by this command: ga(‘create’,’UA-*******-*’,’Auto‘);


Tracker object

If you customize the tracker object name all other commands should be sent to that object

With default object:
ga(‘send’,’pageview’);

With custom name:
ga(‘TrackerName.send’,’pageview’);

Configure Cookie and Sessions

To customize the cookie use the following command:
ga(‘create’,’UA-*******-*’, {
‘cookieName’:’yourCookieName’,
‘cookieDomain’:’store.devdirt.net’,       <default is document.location.hostname>
‘cookieExpires’:60*60*24*28    <sets cookie expirey time in seconds,default is 63072000 or two years>
});

Expiry time doesn’t have anything to do with session timeout.  Session timeout can be set in GA admin panel under Tracking info>Session settings.
