VWO Visual Editor allows you to quickly make changes to the existing web pages and create variations to test. In the Variations list, Control will always be your original webpage while Variation 1 will be the modified version of it.
If your objective is to test multiple changes on your webpages for a different set of audiences, you can add more variations to the test. Also, you can switch between the Control and the Variation from the Variations tab present in the editor.
In addition to creating variations, Visual Editor also lets you define three types of goals- tracking clicks on a link, tracking clicks on an element, and tracking form submissions. To learn more about how to create goals using Visual Editor, refer to Add Goals Using Visual Editor in VWO. You can add multiple goals for the same test from Visual Editor. All the goals you have added using the editor will be listed on the next page where you must indicate one from the list as a primary goal. A primary goal is the one based on which VWO declares a variation as a smart decision or a winner.
If you have multiple goals in your test, then the goal which is directly and exclusively impacted by the changes you make in the test must be chosen as the primary goal. All the metrics like Improvement, Probability to be best, etc., are calculated for all the goals added in the test, however, the smart decisions and winners are declared only for the primary goals.
The Visual Editor for MVT is a bit different compared to the Visual Editor of other testing types. To know about these, refer to Things to Consider While Working With Multivariate Testing in VWO.
Using the VWO Visual Editor, you can edit text, change colors of elements (such as buttons), move, rearrange, hide, or delete elements, or make changes directly to the HTML code snippet. You can also edit images by cropping them, changing contrast, and so on. To read more about various editing tools, VWO Visual Editor Options.
By default, your changes are made directly to a variation. Control, by the virtue of being the original page, cannot be changed.
