Universal Data Object (`utag_data`)

The Universal Data Object (UDO) is a JavaScript object called utag_data in which dynamic data from your webpage is passed to the Tealium tag. The properties in this object are named using plain, vendor neutral terms that are specific to your business.

The following is an example declaration of utag_data, which is done prior to loading the Universal Tag utag.js:

<!-- Tealium Universal Data Object -->
<script type="text/javascript">
  var utag_data={
      "page_type"     : "section",
      "site_section"  : "men",
      "page_name"     : "Men's Fashion | Acme Inc.",
      "country_code"  : "US",
      "currency_code" : "USD"};
</script>

Universal Tag (`utag.js`)

The Universal Tag is a small piece of JavaScript code called utag.js that contains all of the generated code necessary to load third-party tags onto your site. It enables Tealium iQ Tag Management to fire tags by inserting the following code into the page:

<!-- Tealium Universal Tag -->
<script type="text/javascript">
  (function(a,b,c,d) {
      a='//tags.tiqcdn.com/utag/ACCOUNT/PROFILE/ENVIRONMENT/utag.js';
      b=document;c='script';d=b.createElement(c);d.src=a;
      d.type='text/java'+c;d.async=true;
      a=b.getElementsByTagName(c)[0];a.parentNode.insertBefore(d,a)})();
</script>

The utag.js file path contains the following attributes:

Attribute	Description	Example
`account`	Tealium account name	`companyXYZ`
`profile`	Tealium profile name	`main`
`environment`	Tealium environment name	`prod`

Get the Code

To locate and get the code for installing Tealium on your site:

In Tealium iQ Tag Management, click the user menu icon in the upper right corner and select Code Center
Leave the default Javascript Type set to Asynchronous (recommended)
In the Tealium Script tab, click the Select All button to select the code snippet
Copy the selected Universal Tag code to your clipboard

Code Placement

Paste the Universal tag code immediately after the opening <body> tag on every page of your website. This positioning provides the best compatibility with the greatest number of vendors and allows third-party tracking to complete before the visitor navigates to the next page.

The following example shows the code placement:

<head>
  <!-- code -->
</head>
<body>
  <TEALIUM CODE SNIPPET GOES HERE>
  <!-- code -->
</body>

Validate Installation

Use the following tools to validate that your utag.js installation is working properly.

Universal Tag (utag) Debugger

The Universal Tag Debugger (or “utag debugger”) provides an easy way to validate your data layer and tracking calls in real-time as you navigate your site. It’s similar to Web Companion, but is focused on the data captured by each tracking event within utag.js.

The tracking calls made by utag.js are displayed and updated in the tool as you navigate or trigger in-page events.
