For example, if you have a multi-step form and want to determine the impact of the change on a later step, you can run Your experience by simply clicking the Next Step button of the form. Launch and monitor performance Once you've got all the variables, targeting, and settings in place, it's time to hit that shiny Start button you've been eyeing, but just because all you have to do now is wait doesn't mean your work here is done. It is essential to monitor the performance of your test throughout the trial to ensure that nothing is broken, that your alternative does not create a worse

experience for users, and to know when to withdraw or extend the duration of the test. Google Optimize makes it very easy to monitor the results within the tool. In the Reporting tab you can view the data in different ways. At the top you can view sessions Phone Number Data over time broken down by day. This view is important to ensure data is collected and there isn't an alarming drop in numbers. We recommend clicking 'View full graph' rather than just glancing at the thumbnail.

enough, you can often but not alwaysstart to see a pattern, and one way to tell how your test is performing is to look at the Likely to be best section under Reporting. If the percentage is or higher, this indicates a strong probability of winning over time, and in this example, the probability of being the best was  for our variant, which gave us enough data to implement the variant on the live site. In some cases, it's helpful to dig deeper than likely to be the best to understand the data, and fortunately, Optimize does some of that work for you by providing data that directly compares performance between the original and the variant. To do this, Optimize calculates a typical conversion rate, which calculates how your variables perform against a specific goal over time. There are two ways Optimize displays the .
