Once the configuration is correctly performed on the Optimizely X side, you can view the results of test campaigns in AT Internet. So you can go in Explorer and reach the "MV Testing" menu in the "Content" section on the left side of the screen.
Then it’s possible to analyze the results of tests and variations according to AT Internet metrics (visits, page views / visits, bounce rate, etc.).
You can also integrate MV Testing data into your Data Query segmentations in order to associate them with the most relevant elements and identify remarkable behaviors. You can then export MV Testing data in third-party tools, via Data Query or via Data Flow.
