Understand Engagement and Bounce Rates
Decrease Bounce Rate Goal
The decrease bounce rate goal actually counts as conversion a visitor that DOES NOT bounce. So, the biggest the conversion rate, the lowest the bounce rate and therefore the better. We count a visitor as a non bounce when they visit more than one page or when their visit session is longer than 10 seconds.
Increase Engagement Goal
Goal increase engagement is triggered when a visitor is clicking on any link on the pages you are testing on.
