Step 6: QA your experiment


Now that you’ve set up all the components of your experiment, it’s time to make sure it works. As with any tool that publishes content to the web, you should always be sure that the changes you made through Optimizely will render and function properly. After all, your experiments affect your visitor’s experience.

Don’t take the risk that something will publish incorrectly, and follow our Pre-Launch Checklist, which you can find here. It will add a little time to your preview and QA (quality assurance) process, but following it will reduce errors and help you get things right the first time.

There are several techniques you can use to QA your experiment, which you can learn about in our resources on the QA process. However, we suggest you start with two basic and easy-to-use tools: The Preview Mode and the Force Parameter.

  • Preview mode allows you to make sure your changes look right, check that you're in the right audiences and dimensions, make sure your click goals are firing, and test viewing your experiment as a specific viewer.
  • With Force Parameter, you can use query parameters that allow you to view a specific variation, check the tracking on events in a variation, create a Javascript log, and disable all Optimizely code on the page completely.
