When I check the reports for the Control and Variation versions of my website, they are different despite the fact that both versions are the same.
Typically, VWO campaigns help you to compare different versions of your web pages and determine the statistical significance of the changes implemented. Unless the statistical differences are huge, you can simply ignore the results. The minor differences in the results data could be because of the way VWO randomly redirects your website traffic between control and variations.
For example, during the initial stage of a campaign, you may notice that a variation has a 10% conversion rate while the control has 8% conversion rate. As you test more traffic, this difference should come down and the conversion rate will be the same.
