Today, building customer loyalty is an essential prerogative for the brand, characterised by continuous and targeted attention throughout the customer life cycle. An effective loyalty strategy must be able to generate value, not only in the context of the purchasing process but also in fostering a daily and meaningful interaction between the user and the brand. This principle is reflected in the concept of “Behavioural Loyalty”, a multi-channel approach that integrates advanced digital solutions, business intelligence technologies and machine learning. These tools make it possible to acquire in-depth knowledge of the individual Customer, capturing tastes, preferences and trends and thus allowing the construction of personalised relationship paths that evolve over time.
