The most useful feature is that it helps you to track your ROI for each campaign which makes us more confident about our campaigns as well! I would like if they can add some other features such as; A/B testing option with live data update so we could easily test different versions without spending money or time over multiple tests just by one click!! Great tool when used properly but sometimes there's no proper instructions from their support team regarding how this software works (or lack thereof). We needed something that will help boost revenue per visit while still maintaining good user experience at all times since users have low tolerance towards any website being slow even though its not intentional nor maliciously done.
