PHP Split Tests
Creating a new PHP split test
You would need to set up a PHP test when you want to see if a a change in content within one page on your site draws more visitors and results in more conversions. This test is more applicable to changes in the design and layout of your site's content and they require you to actually make the change in the source code of the page at the time when you set up the test.
When you select this option a new window opens where you can enter the following information: the name of the test, the URL of the page you want to test and the percentage of visitors you want to show the new version of the page to. Also, you can enter a description of what exactly you are testing. (say, a changed layout or new content on your site, different colors, etc). When you click on Create, you will see the source code of the selected page in two separate fields. One will be your version A, the other is version B. You will then introduce the change into the code of one of the versions ( obviously, here some HTML skills are required), publish it on the site, and wait to see the results. The PHP split test gets saved on the left side of the Test Centre page, under the name you have chosen. This is where you will go to retrieve it and run the report with the results.
In the screenshot below you see how one or more tests you compiled will be displayed in your test centre window. Under each of the tests, you have the options Preview, Edit and Close. Preview allows you to see how page A and B will look like in the internet browser ( how your site visitors will see them). In Edit you are basically going back to the Create test screen where you can change the URL or description. The Close option is self-explanatory.
