If you'd like to run Optimizely tests on your ControlShift instance, you can enable Optimizely from your organization's settings page. To get started, go to the admin homepage > Settings > Options tab > A/B Testing section.
To begin running a test, enter your Optimizely project ID into the text box and then check the Use Optimizely box to enable the script. When you're done running your test, just uncheck the box.*
*Why should you turn Optimizely off when you're not running a test? Optimizely slows pages load times a bit. Therefore, when you're not running a test, you may want to turn off the Optimizely script.
