|

<p>Custom variables are name-value pair tags
|
||
that you can insert in your tracking code in order to refine Google Analytics
|
||
tracking. With custom variables, you can define additional segments to apply
|
||
to your visitors other than the ones already provided by Analytics. This document
|
||
describes custom variables and how you can set them up.</p>

<h2 id="overview">Overview</h2>
|
||
<p>
|
||
You'll get the most out of custom variables if you understand
|
||
the basic visitor interaction model used in Google Analytics. In this model,
|
||
the visitor interacts with your content over a period of time, and the engagement
|
||
with your site is broken down into a hierarchy. </p>
|
||
|
||
<p><img src="11_gaTrackingCustomVariables-Dateien/visitorSessionInteraction.png" style="padding-left: 10px;" align="right">The
|
||
diagram illustrates this model for a single visitor to your site, where each
|
||
block represents the number of user sessions and interactions from that particular
|
||
user. </p>
|
||
<p>Each level in this model is defined as follows:
|
||
</p><ul>
|
||
<li><strong>Visitor</strong>—the client that visits the site, such
|
||
as the browser or mobile phone operated by a person.</li>
|
||
<li><strong>Session</strong>—the period of time during which the visitor
|
||
is active on the site.</li>
|
||
<li><strong>Page</strong>—activity
|
||
on the user's behalf which sends a GIF request to the Analytics servers.
|
||
This is typically characterized by a pageview, but it can include:
|
||
<ul>
|
||
<li>a pageview</li>
|
||
<li>an event (e.g. click on a movie button)</li>
|
||
</ul>
|
||
</li>
|
||
</ul>
|
||
|
||
<p>These three levels of interaction make up the <em>scope</em> of visitor engagement.
|
||
This is important to custom variables because each custom
|
||
variable is restricted to a particular scope.
|
||
For example, you might want to know the number of sessions where visitors removed
|
||
an item from their shopping cart. For that particular case, you would define
|
||
the custom variable to the session level, so that the entire session for that
|
||
visitor is flagged as one in which items were removed from online carts.</p>

|
||
</p><h2 id="setup">Using Custom Variables</h2>
|
||
<p>Because you can set up a variety of custom variables to track user activity
|
||
for your site, you'll most commonly create your own JavaScript
|
||
utilities to manage them. Your script will use the basic method
|
||
for creating a custom variable as follows:</p>
|
||
<p><code>_setCustomVar(index, name, value, opt_scope)</code></p>
|
||
<p>This method accepts four parameters:
|
||
</p><ul>
|
||
<li><strong>index</strong>—The slot for the custom variable. <strong>Required.</strong> This is
|
||
a number whose value can range from <code>1</code> - <code>5</code>,
|
||
inclusive. A custom variable should be placed in one slot only and not be
|
||
re-used across different slots.</li>
|
||
<li><strong>name</strong>—The name for the custom variable. <strong>Required.</strong> This is a
|
||
string that identifies the custom variable and appears in the top-level <em>Custom
|
||
Variables</em> report
|
||
of the Analytics reports.</li>
|
||
<li><strong>value</strong>—The value for the custom variable. <strong>Required.</strong> This is
|
||
a string that is paired with a name. You can pair a number of values with
|
||
a custom variable name. The value appears in the table list of the UI for
|
||
a selected variable name. Typically, you will have two or more values for
|
||
a given name. For example, you might define a custom variable name <code>gender</code> and
|
||
supply <code>male</code> and <code>female</code> as two possible values.</li>
|
||
<li><strong>opt_scope</strong>—The scope for the custom variable. <em>Optional.</em> As
|
||
described above, the scope defines the level of user engagement with your
|
||
site. It is a number whose possible values are <code>1</code> (visitor-level),
|
||
<code>2</code> (session-level), or <code>3</code> (page-level). When left
|
||
undefined, the custom variable scope defaults to page-level interaction.</li>
|
||
</ul>
|
||
|
||
<p>The following code snippet illustrates how you might set a custom variable
|
||
for tracking those visits where users
|
||
removed items from their shopping cart. Here, the <code>_setCustomVar()</code> method
|
||
is called just before a <code>_trackEvent()</code> method, so that it gets
|
||
delivered in the GIF request sent by the <code>_trackEvent()</code> method.
|
||
It uses the name <code>Items Removed</code> with the value <code>Yes</code> in
|
||
order to define that activity from the website users. In addition, it would
|
||
make sense to also set a default custom variable
|
||
for <code>Items Removed</code> and <code>No</code>. In this way, you would
|
||
have a count of visits where items were removed from shopping carts, and a
|
||
count of visits that didn't include item removal.</p>

|
||
</p><h2 id="examples">Example Use Cases</h2>
|
||
<p>Custom variables can be implemented in many different ways, depending upon
|
||
your website model and business needs. The examples explore different use cases,
|
||
where each one illustrates a different level of scope:</p>
|
||
<ul id="use-case-list">
|
||
<li><a href="#pageLevel">Page-level Custom Variables</a></li>
|
||
<li><a href="#sessionLevel">Session-level Custom Variables</a></li>
|
||
<li><a href="#visitorLevel">Visitor-level Custom Variables</a></li>
|
||
</ul>
|
||
<h3 id="pageLevel">Page-level Custom Variables</h3>
|
||
<p>Use page-level custom variables to define a collection of page-level
|
||
activities by your users. </p>
|
||
<p>For example, suppose you manage the website for an
|
||
online newspaper, where visitors view many different articles. While it is
|
||
easy to determine which particular articles are the most popular, you can now
|
||
also use custom variables to determine which <em>sections</em> of
|
||
the newspaper are popular. This is done by setting a custom variable at the
|
||
page level for each article, where the section for that article is set as
|
||
a custom variable. For example, you might have sections such as <em>Life & Style</em>, <em>Opinion</em>,
|
||
and <em>Business</em>. You could set a custom variable to track all your articles
|
||
by section.</p>

|
||
|
||
<p>Let's continue with this example and suppose that you not only want to tag
|
||
the section for a particular article, but also the sub-section. For example,
|
||
the <em>Life & Style</em> section for your newspaper might have a number
|
||
of sub-sections
|
||
as well, such as <em>Food & Drink</em>, <em>Fashion</em>, and <em>Sports</em>.
|
||
So, for a particular article, you can track both the section and the sub-section.
|
||
You could set an additional custom variable to track all your articles by sub-section.</p>

|
||
<p>In this example, you set two simultaneous page-level custom variables for
|
||
a single page. For any single page, you can track up to five custom variables,
|
||
each with a separate slot. This means that you could assign 3 additional custom
|
||
variables on this same page. For all articles on your website, you can set
|
||
up an array of page-level custom variables to track them by a variety of sections
|
||
and sub-sections. For more information on how to correctly use page-level custom

variables, see <a href="#usage">Usage

|

<p>Use session-level custom variables to distinguish different visitor experiences

across sessions. </p>
|

<p>For example, if your website offer users the ability to login, you can use

a custom variable scoped to the session level for user login status. In that

way, you can segment visits by those from logged in members versus anonymous

</p><h3 id="visitorLevel">Visitor-level Custom Variables</h3>
|
||
<p>Use visitor-level custom variables to distinguish categories of visitors across
|
||
multiple sessions.</p>
|
||
<p>For example, if your websites offers premium content to paying subscribers,
|
||
you can set a visit-level custom variable to analyze which users are paying
|
||
members, at which level of payment, and which users are using the free level
|
||
of service for the site. You would likely set this custom variable as a one-time
|
||
function, since the value would persist across the life of the visitor cookie.</p>

</p><h3 id="mixedTypes">Mixing Variable Types</h3>
|
||
<p>When you use multiple page-, session-, and visitor-level custom variables
|
||
for your web property, you need to carefully determine the re-use of slots. If
|
||
a situation arises on your website where a page or session-level custom variable
|
||
<em>uses the same slot at the same time</em> a page-level variable is set, only the
|
||
session-level (or page-level) variable will be recorded.</p>
|
||
<p>The following scenarios illustrate a mix of page, session, and visitor level
|
||
variables set by activity from a single user on the same browser. In each (1)
|
||
or (2) indicates a particular slot used by the custom variable and S: indicates
|
||
the scope.</p>
|
||
<h4>Case 1 - One visit, three pageviews</h4>
|
||
<table border="0">
|
||

|
||
<th><strong>Visit 1</strong></th>
|
||
<td><strong>Page 1</strong><br>

(1) S:page-level <br>
|
||
<code>section=opinion</code></td>
|
||

|
||
(1) S: session-level<br>
|
||
<code>login=true</code></td>
|
||
<td><strong>Page 3</strong><br>
|
||
(1) S: session-level<br>
|
||
<code>converted=true</code></td>
|
||
</tr>
|
||
</tbody></table>
|
||
<p>The report for visits would be: </p>
|
||
<ul>
|
||
<li># visits for section=opinion: 0</li>
|
||
<li># visits for login=true: 0</li>
|
||
<li># visits for converted=true: 1</li>
|
||
</ul>
|
||
<p>Here the final page calls a session-level variable that re-uses the same slot,
|
||
and it receives precedence. </p>
|
||
<h4>Case 2 - Three visits</h4>
|
||
<table border="0">
|
||
<tbody><tr>
|

<th><strong>Visit 1</strong></th>

<li># visits for gender=male: 2</li>
|
||
<li># visits for converted=false: 2</li>
|
||
</ul>
|
||
<p>Here the page-level variable is called after a visitor-level variable that
|
||
used the same slot. In this order, the visitor-level variable does not over-write
|
||
the page-level variable. </p>

<li># visits for gender=male: 2</li>
|

<li># visits for converted=false: 1</li>
|
||
</ul>
|
||
<p>This is a variation from the previous case, where the final visit sets only
|
||
one CV and re-uses a slot called in the first visit.</p>
|
||
<h3 id="recommended">Recommended Practices</h3>
|
||
<ul>
|
||
<li><strong>Do not use duplicate key names across slots.</strong></li>
|
||
<li><strong>You have up to 5 simultaneous custom variables for use in a single
|
||
request (e.g. pageview or event call).</strong><br>
|
||
The
|
||
sum of all your custom varaiables cannot exceed 5 in any given request (i.e.
|
||
you cannot have 5 visitor and 5 session custom variables set simultaneously).</li>
|
||
<li><strong>Call the <code>_setCustomVar()</code> function when it can be set prior
|
||
to a pageview or event GIF request.</strong><br>
|
||
In certain cases this might not be possible,
|
||
and you will need to set another <code>_trackPageview()</code> request <em>after</em> setting
|
||
a custom variable. This is typically only necessary in those situations where
|
||
the user triggers a session- or visit-level custom var, where it is not possible
|
||
to bundle that method with a pageview, event, or ecommerce tracking call.</li>
|
||
<li><strong>Use a slot matrix to track large numbers of custom variables.</strong><br>
|
||
If you have complex tracking requirements, where you have a mix of page-
|
||
and session-level variables that might collide,
|
||
you should build a slot matrix to ensure that session-level variables do not
|
||
inadvertently over-ride page-level variables.</li>
|
||
<li><strong>Consider using Event Tracking for certain applications, rather
|
||
than custom variables.</strong><br>
|
||
For
|
||
example, suppose you have an online music store and you want to track both
|
||
login sessions, purchase attempt sessions, and sessions where music samples
|
||
were played. It would make sense to use Event Tracking to track the number
|
||
of attempts to play music rather than using session-level variables to
|
||
achieve this. Here, you could use the 4th value parameter of the event
|
||
tracking call to pass in session data from your own cookies. </li>
|
||
<li><strong>Don't use session-level variables to track behavior you can track
|
||
with page-level variables.</strong><br>
|
||
For example, suppose you track login status and shopping
|
||
attempt status by sessions, and your site offers a "Members'
|
||
special" page
|
||
that you also want to track. Since a page-level custom variable will show the
|
||
number of visits to that particular variable, you will already have available
|
||
the number of visits that included that page at least once. </li>
