Why do companies lose millions of dollars every year? One of the reasons is a lack of understanding of their customers. Ignorance of their needs, habits and behaviour leads to reduced loyalty, customer churn and loss of revenue. Recent studies show that only 15% of companies have studied their customers well. Imagine this: 85% of companies do not use the potential of their data to identify customer trends and improve customer relationships! And in today's realities, when the frequency of purchases depends on security, electricity, water and the Internet, businesses risk losing market share without proper knowledge and adaptation. This book will help you by offering: simple and effective customer analytics tools; practical methods and strategies for optimising marketing efforts and increasing profitability; and the experience of Airbnb, Amazon, Netflix, and other market leaders. It's time to turn your own data into valuable knowledge, make informed decisions, adapt to changes, and beat the competition. Grow your business through deep customer insights!
