How do I implement the Optimizely snippet?

Implementing the Optimizely snippet is as easy as a one-time copy and paste of your unique, single line of javascript into your page's html header. Watch the quick walkthrough video.

How do I build my first experiment?

To build an experiment, load the URL of the page you'd like to test in the Optimizely editor. From there, you can build your page variations using the visual editor and launch your experiment. Watch the overview video.

What should I test with Optimizely?
