This book will help you to create huge sales for yourself or any organization. Before the advent of digital marketing, businesses all over the world made use of the conventional method of marketing which involved door-to-door marketing. This method was effective to a reasonable level as it encouraged a personal connection between the salesperson and his customer. However, the major pitfall with the door-to door marketing was that it was really slow and time consuming. Despite the fact that the term 'digital marketing' was first used in the 1990s, it became more effective in the 2000s. According to Wikipedia, digital marketing is an umbrella term for the targeted, measurable and interactive marketing of products or services using digital technologies to reach and convert leads into customers and retain them. There are billions of people in the online world today and if you can reach even a fraction of them, you will be able to create huge sales for yourself or any organization. All what you need to know about digital marketing is this book.
