Google Tag Manager allows you to conveniently manage tags (such as tracking and marketing optimization JavaScript tags) on your site. You can add and update AdWords, Google Analytics, Floodlight and non-Google tags from the Google Tag Manager user interface instead of editing site code. This reduces errors, frees you from having to involve a webmaster, and allows you to quickly deploy tags on your site.
Step-by-step guide
- Create an account
- Check resource
- Set the Google Tag Manager ID
- Create a template (optional)
- Set templates
Create an account
See http://www.google.com/tagmanager/get-started.html on how to setup an account to use with Google Tag manager.
Check resource
Check resource rcGoogleTagManagerInitialiser. It should contain something similar to the following:
<!-- Google Tag Manager -->
<noscript><iframe src="//www.googletagmanager.com/ns.html?id={0}" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});
var f=d.getElementsByTagName(s)[0], j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';
j.async=true;j.src= '//www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','{0}');</script>
<!-- End Google Tag Manager -->
Set the Google Tag Manager ID
Go to the Settings admin page and set the Google Tag Manager ID to what Google has given you (most likely in the format 'GTM-XXXX').
Create a template (optional)
This is not necessary as there is a default template that you can use, called CV_OpeningBodyTemplate. This template contains the following:
[TemplateUtil.GoogleTagManagerInitialiser]
If you create your own template:
- The template does NOT have to contain the tag [TemplateUtil.GoogleTagManagerInitialiser]. If it is not in the template, the 'snippet' will not be present on the page and the Google Tag Manager will not work.
- If the tag [TemplateUtil.GoogleTagManagerInitialiser] is in the template, it must be at the start of the template (i.e. no text can come before it).
Set templates
There are two templates that you can set:
- Global - one for all users.
- Role based - one for users in specific roles.
The default template is called CV_OpeningBodyTemplate.
The role based template will be checked first and used if it exists. If it doesn't exist, the global template will be used if it exists.
Global
To use the tag manager for all users, go to the default templates admin page. Set the Opening Body Template to the default template or another template you created.
Role based
To use the tag manager for users in specific roles, go to the role management admin page (see Templates tab). Set the Opening Body Template to the default template or another template you created.
