As we expected, there is no direct connection between our campaigns and the incomes from off-line sources
(printing and outdoor advertising).Moreover, during the months that the campaigns took place it was noted a decrease
in revenue even from online activities, which is normal, advertising contracts for that period were contracted
previously. Instead, it can be seen an increase in income from online advertising campaign in the next month. The
increase becomes significant in the third campaign, and the incomes do not fall to the amount from the previous
months. A possible explanation would be that a succession of marketing campaigns tend to loyal customers. This
assumption remains to be validated in the following months of the study.
