I would like to know if we always need to add a control group?
Especially right now during the Covid-19 crisis, we need to add one or two informational notifications in our eShops for our customers (regarding delivery time, safety etc.). They should be seen by every visitor, therefore we don't add a control group. On the other hand, I would like to know if they have an impact on our revenue, and yes if it's positive or negative.
