Non-Standard Experiments

Non-Standard Experiments (Testing Static Content)

Background

Before we go into the speciﬁcs of setting up experiments for non-standard setups, let’s elaborate on some

GWO concepts.

Earlier in this guide, we used the terms test page and conversion page (in singular form) to keep things

simple. As you set up an experiment, GWO asks for the URL for yourtest page (or pages, for A/B

experiments) and the URL for your conversion page.GWO then continues to explain how to install the

JavaScript code onthe test page and the conversion page.

These terms imply that your test elements are all part of asingle test pagewith a speciﬁc URL, and that

conversions happen on aspeciﬁc URL.

But what if this isn’t the case?

Let’s look at how to set up more complicated scenarios. As we saw earlier, GWO has four piecesof JavaScript

(three for A/B):

1. The Control Script at the top of the page (this loads the JavaScript functions used to replace content

for MVT or redirect the user for A/B)

2. The Section Script (utmx_section) right before a section with a </noscript> at the end (for MVT only)

3. The Tracking Script JavaScript

4. The Conversion Script JavaScript

This time, instead of thinking in terms of a test page and conversion page with speciﬁc URLs, think in terms

of executing some JavaScript for each one of the functions.

• To load the utmx section function, call the Control Script, which then invokes siteopt.js, which will

provide an implementation of the utmx section function.

• To replace the content for a section, call the Section Script. This applies to MVT experiments only.

The utmx_section alone is not capable of completing this work. You need an ending </noscript> tab

to delineate where the section ends.

• To register a visit, call the Tracking Script.

• To register a conversion, call the Conversion Script.

Here are a few other details you should know:

Purpose of utmx_section

The utmx_section function call just before a section, and the </noscript> at the end of a section, are actually

serving two different purposes.

1. When the function is executed, it marks where the section begins and ends (denoted by </noscript>),

and it may replace the content. When a user is viewing the original content, it leaves anything

between those tags untouched.

2. When the experiment is being set up, GWO looks for the utmx_section call to identify the names and

order of the sections.
