The initial settings you need to configure when planning a test are within the Title section. 

First, you need to name your test. 

Pro tip: Give your campaign a meaningful name. It is a good idea to identify the page and the keyword you are targeting within the test.

Next, the interface will ask you to write a brief description. This is not a mandatory step, however. Add in information that can be useful for you and your team in the future or simply leave it blank.
