We currently only use VWO for our e-commerce division. While it does solve intra-personal ideas on what designs work, it allows us to maximize our ability to provide a better customer experience. When we use testing, we aren't looking for little lifts in conversions but large leaps - and VWO allows us to do that easily and quickly.
This has definitely been a crucial part in a strategy we have moving forward. We have made leaps in what we were doing back then to now - and moving forward it will also give us the opportunity to test more, to understand more and to act more on things that impact our business as a whole.
