You have the opportunity to test four types of content:

• Content split test – you set up a number of variations and insert a code in your post, page, widget, or theme where you want the variations to be.
• Stylesheet split test – you set up a number of different stylesheets to test, e.g. the color of ‘Read more’ or ‘Buy now’ buttons.
• Javascript split test – you set up a number of different javascripts to test. This enables testing almost anything on your site.
• Theme split test – you test between a number of themes.

Tracking goal completions:

• Goal pages – you insert a goal completion code in your pages, posts, or widgets.
• Link clicks – you track every click on a link, e.g. links to other sites.
• Manual tracking – you track goals manually via javascript.

You have access to a number of options to measure your split tests:

• Built-in measuring – use the built-in measurement statistics.
• Custom measuring – use Google Analytics or another of your choice.
