In Personizely you can create A/B tests and multivariate tests. These allow you to create different versions of a widget and track which one of them performs better.
All the visual and interactivity settings of the widget are variations-specific and will only affect the variation you currently edit. This allows creating totally different versions of the widget visually and conceptually.
You can use a different set of triggers for each variation in order to test which triggers perform better for your widgets.
You can choose different close triggers for each variation in order to test which close triggers perform better for your widgets.
