The Snippet should be placed .

  • As high in the head tag as possible
  • As low in the head tag as possible
  • In the body
  • At the bottom of the footer

If the Snippet is placed incorrectly, you risk:

  • The wrong variation appearing
  • Page flashing
  • Error messages appearing to visitors
  • The browser shutting down

The placement of the Snippet is important because Optimizely:

  • Can cause the experiment to report improperly if it’s in the wrong place
  • Makes changes to your webpage as it loads
  • Enables you to move the snippet to any location after setup
