The Techie Guide to Google Website Optimizer

Non-Standard Experiments

For the conversion page, locally create a dummy ﬁle (such as conversion_dummy_ﬁle.html) containing

nothing but the Conversion Script. This is especially helpful if the conversion page requires a purchase and

is hard to view without making an actual purchase. In any case, you’ll need to add the Conversion Script to

the real conversion page before you launch the experiment.

Step 3: Create variations

Once you’ve reached Step 3, creating variations is the same as in the simple scenario. If your variations

contain dynamic content, you can see how to set that up in the next section.

Step 4: Review and launch

This step should really be called “Review, preview and launch”.

While GWO used your own local ﬁles to helpduringthe experiment setup stage, by this point you should

have all the GWO code in place so it appears in the HTML source on an actual web server. If you have access

to the test page from your own PC (for instance, on a development server that is not publiclyaccessible), the

preview function will work ﬁne. The preview function calls the page based on the URL you provided in Step

1, and adds a string that looks like a local anchor (starting with #).

For example, to preview: http://dev.mysite.com/product_page.php?pid=123

GWO will use a URL that looks like this:

http://de v.mysite.com/product_page.php?pid=123#utmxid=EAAAACmLHKpzyPXnHnp

og9gHi14;utmxpreview=0-0-0;utmxreload=1

Experiment ID is an alpha numeric sequence (AgAAAIuElaplZk1wAusMbP0ZUYo, for example). To ﬁnd

this ID, open the Website Optimizer preview page for your experiment; the value of the query parameter

experiment is the experiment ID.

Combination is the combination you want to preview. It is a sequence of numbers, separated by dashes. Each

number represents a page section in your experiment, and the value of each number identiﬁes the variation.

For example, if your experiment has three sections, the combination 2-0-1 speciﬁes the second variation of

the ﬁrst section, the original of the second section, and the ﬁrst variation of the third section. Variation order

is determined by the order of the Section Scripts on the test page. To see the original combination for an

experiment with four sections, you would specify 0-0-0-0.

For example:

http://ww w.mysite.com/product_page#utmxid=EAAAAOYh8q79WlRUYLWrG7ax48I;utm

xpreview=0-2-0

Once you’ve appended the preview string to your test page URL, you’ll need to force a refresh to get the

browser to fetch the requested variation. This can usually be achieved by hitting CTRL+F5 in the browser.

(The forced refresh is necessary because the speciﬁed combination appears after a ‘#’ symbol and is not

considered part of the cacheable URL.)

If the test page is not directly accessible within the GWO preview, you can copy and paste the “preview

string” and append it to the live page. Let’s say you set up the experiment on a dev server and provided

URLs for the dev server during theexperimentsetup, then copied the GWO code to the live server. In that

case, before launching the experiment you can copy the ﬁles to the production server and then replace the

preview URLs with ones for production.
