What is Lead Generation?
Lead generation describes the marketing process of stimulating and capturing interest in a product or service for the purpose of developing sales pipeline.
Lead generation often uses digital channels, and has been undergoing substantial changes in recent years from the rise of new online and social techniques. In particular, the abundance of information readily available online has led to the rise of the "self-directed buyer" and the emergence of new techniques to develop and qualify potential leads before passing them to sales.
